+# After [![Build Status][1]][2]
+
+Invoke callback after n calls
+
+## Status: production ready
+
+## Example
+
+```js
+var after = require("after")
+var db = require("./db") // some db.
+
+var updateUser = function (req, res) {
+ // use after to run two tasks in parallel,
+ // namely get request body and get session
+ // then run updateUser with the results
+ var next = after(2, updateUser)
+ var results = {}
+
+ getJSONBody(req, res, function (err, body) {
+ if (err) return next(err)
+
+ results.body = body
+ next(null, results)
+ })
+
+ getSessionUser(req, res, function (err, user) {
+ if (err) return next(err)
+
+ results.user = user
+ next(null, results)
+ })
+
+ // now do the thing!
+ function updateUser(err, result) {
+ if (err) {
+ res.statusCode = 500
+ return res.end("Unexpected Error")
+ }
+
+ if (!result.user || result.user.role !== "admin") {
+ res.statusCode = 403
+ return res.end("Permission Denied")
+ }
+
+ db.put("users:" + req.params.userId, result.body, function (err) {
+ if (err) {
+ res.statusCode = 500
+ return res.end("Unexpected Error")
+ }
+
+ res.statusCode = 200
+ res.end("Ok")
+ })
+ }
+}
+```
+
+## Naive Example
+
+```js
+var after = require("after")
+ , next = after(3, logItWorks)
+
+next()
+next()
+next() // it works
+
+function logItWorks() {
+ console.log("it works!")
+}
+```
+
+## Example with error handling
+
+```js
+var after = require("after")
+ , next = after(3, logError)
+
+next()
+next(new Error("oops")) // logs oops
+next() // does nothing
+
+// This callback is only called once.
+// If there is an error the callback gets called immediately
+// this avoids the situation where errors get lost.
+function logError(err) {
+ console.log(err)
+}
+```

+# Async-Limiter
+
+A module for limiting concurrent asynchronous actions in flight. Forked from [queue](https://github.com/jessetane/queue).
+
+[](http://www.npmjs.org/async-limiter)
+[](https://travis-ci.org/STRML/async-limiter)
+[](https://coveralls.io/r/STRML/async-limiter)
+
+This module exports a class `Limiter` that implements some of the `Array` API.
+Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods.
+
+## Motivation
+
+Certain functions, like `zlib`, have [undesirable behavior](https://github.com/nodejs/node/issues/8871#issuecomment-250915913) when
+run at infinite concurrency.
+
+In this case, it is actually faster, and takes far less memory, to limit concurrency.
+
+This module should do the absolute minimum work necessary to queue up functions. PRs are welcome that would
+make this module faster or lighter, but new functionality is not desired.
+
+Style should confirm to nodejs/node style.
+
+## Example
+
+``` javascript
+var Limiter = require('async-limiter')
+
+var t = new Limiter({concurrency: 2});
+var results = []
+
+// add jobs using the familiar Array API
+t.push(function (cb) {
+ results.push('two')
+ cb()
+})
+
+t.push(
+ function (cb) {
+ results.push('four')
+ cb()
+ },
+ function (cb) {
+ results.push('five')
+ cb()
+ }
+)
+
+t.unshift(function (cb) {
+ results.push('one')
+ cb()
+})
+
+t.splice(2, 0, function (cb) {
+ results.push('three')
+ cb()
+})
+
+// Jobs run automatically. If you want a callback when all are done,
+// call 'onDone()'.
+t.onDone(function () {
+ console.log('all done:', results)
+})
+```
+
+## Zlib Example
+
+```js
+const zlib = require('zlib');
+const Limiter = require('async-limiter');
+
+const message = {some: "data"};
+const payload = new Buffer(JSON.stringify(message));
+
+// Try with different concurrency values to see how this actually
+// slows significantly with higher concurrency!
+//
+// 5: 1398.607ms
+// 10: 1375.668ms
+// Infinity: 4423.300ms
+//
+const t = new Limiter({concurrency: 5});
+function deflate(payload, cb) {
+ t.push(function(done) {
+ zlib.deflate(payload, function(err, buffer) {
+ done();
+ cb(err, buffer);
+ });
+ });
+}
+
+console.time('deflate');
+for(let i = 0; i < 30000; ++i) {
+ deflate(payload, function (err, buffer) {});
+}
+t.onDone(function() {
+ console.timeEnd('deflate');
+});
+```
+
+## Install
+
+`npm install async-limiter`
+
+## Test
+
+`npm test`
+
+## API
+
+### `var t = new Limiter([opts])`
+Constructor. `opts` may contain inital values for:
+* `t.concurrency`
+
+## Instance methods
+
+### `t.onDone(fn)`
+`fn` will be called once and only once, when the queue is empty.
+
+## Instance methods mixed in from `Array`
+Mozilla has docs on how these methods work [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array).
+### `t.push(element1, ..., elementN)`
+### `t.unshift(element1, ..., elementN)`
+### `t.splice(index , howMany[, element1[, ...[, elementN]]])`
+
+## Properties
+### `t.concurrency`
+Max number of jobs the queue should process concurrently, defaults to `Infinity`.
+
+### `t.length`
+Jobs pending + jobs to process (readonly).

+# backo
+
+ Simple exponential backoff because the others seem to have weird abstractions.
+
+## Installation
+
+```
+$ npm install backo
+```
+
+## Options
+
+ - `min` initial timeout in milliseconds [100]
+ - `max` max timeout [10000]
+ - `jitter` [0]
+ - `factor` [2]
+
+## Example
+
+```js
+var Backoff = require('backo');
+var backoff = new Backoff({ min: 100, max: 20000 });
+
+setTimeout(function(){
+ something.reconnect();
+}, backoff.duration());
+
+// later when something works
+backoff.reset()

+base64id
+========
+
+Node.js module that generates a base64 id.
+
+Uses crypto.randomBytes when available, falls back to unsafe methods for node.js <= 0.4.
+
+To increase performance, random bytes are buffered to minimize the number of synchronous calls to crypto.randomBytes.
+
+## Installation
+
+ $ npm install base64id
+
+## Usage
+
+ var base64id = require('base64id');
+
+ var id = base64id.generateId();

+
+## Installation
+
+ $ npm install better-assert
+
+## Example
+
+ By default assertions are enabled, however the __NO_ASSERT__ environment variable
+ will deactivate them when truthy.
+
+```js
+var assert = require('better-assert');
+
+test();
+
+function test() {
+ var user = { name: 'tobi' };
+ assert('tobi' == user.name);
+ assert('number' == typeof user.age);
+}
+
+AssertionError: 'number' == typeof user.age

+# Emitter [](https://travis-ci.org/component/emitter)
+
+ Event emitter component.
+
+## Installation
+
+```
+$ component install component/emitter
+```
+
+## API
+
+### Emitter(obj)
+
+ The `Emitter` may also be used as a mixin. For example
+ a "plain" object may become an emitter, or you may
+ extend an existing prototype.
+
+ As an `Emitter` instance:
+
+```js
+var Emitter = require('emitter');
+var emitter = new Emitter;
+emitter.emit('something');
+```
+
+ As a mixin:
+
+```js
+var Emitter = require('emitter');
+var user = { name: 'tobi' };
+Emitter(user);
+
+user.emit('im a user');
+```
+
+ As a prototype mixin:
+
+```js
+var Emitter = require('emitter');
+Emitter(User.prototype);
+```
+
+### Emitter#on(event, fn)
+
+ Register an `event` handler `fn`.
+
+### Emitter#once(event, fn)
+
+ Register a single-shot `event` handler `fn`,
+ removed immediately after it is invoked the
+ first time.
+
+### Emitter#off(event, fn)
+
+ * Pass `event` and `fn` to remove a listener.
+ * Pass `event` to remove all listeners on that event.
+ * Pass nothing to remove all listeners on all events.
+
+### Emitter#emit(event, ...)
+
+ Emit an `event` with variable option args.
+
+### Emitter#listeners(event)
+
+ Return an array of callbacks, or an empty array.
+
+### Emitter#hasListeners(event)
+
+ Check if this emitter has `event` handlers.

+# EJS
+
+Embedded JavaScript templates
+
+[](https://travis-ci.org/mde/ejs)
+[](https://david-dm.org/mde/ejs?type=dev)
+[](https://snyk.io/test/npm/ejs)
+
+## Installation
+
+```bash
+$ npm install ejs
+```
+
+## Features
+
+ * Control flow with `<% %>`
+ * Escaped output with `<%= %>` (escape function configurable)
+ * Unescaped raw output with `<%- %>`
+ * Newline-trim mode ('newline slurping') with `-%>` ending tag
+ * Whitespace-trim mode (slurp all whitespace) for control flow with `<%_ _%>`
+ * Custom delimiters (e.g., use `<? ?>` instead of `<% %>`)
+ * Includes
+ * Client-side support
+ * Static caching of intermediate JavaScript
+ * Static caching of templates
+ * Complies with the [Express](http://expressjs.com) view system
+
+## Example
+
+```ejs
+<% if (user) { %>
+ <h2><%= user.name %></h2>
+<% } %>
+```
+
+Try EJS online at: https://ionicabizau.github.io/ejs-playground/.
+
+## Usage
+
+```javascript
+let template = ejs.compile(str, options);
+template(data);
+// => Rendered HTML string
+
+ejs.render(str, data, options);
+// => Rendered HTML string
+
+ejs.renderFile(filename, data, options, function(err, str){
+ // str => Rendered HTML string
+});
+```
+
+It is also possible to use `ejs.render(dataAndOptions);` where you pass
+everything in a single object. In that case, you'll end up with local variables
+for all the passed options. However, be aware that your code could break if we
+add an option with the same name as one of your data object's properties.
+Therefore, we do not recommend using this shortcut.
+
+## Options
+
+ - `cache` Compiled functions are cached, requires `filename`
+ - `filename` The name of the file being rendered. Not required if you
+ are using `renderFile()`. Used by `cache` to key caches, and for includes.
+ - `root` Set project root for includes with an absolute path (/file.ejs).
+ - `context` Function execution context
+ - `compileDebug` When `false` no debug instrumentation is compiled
+ - `client` When `true`, compiles a function that can be rendered
+ in the browser without needing to load the EJS Runtime
+ ([ejs.min.js](https://github.com/mde/ejs/releases/latest)).
+ - `delimiter` Character to use with angle brackets for open/close
+ - `debug` Output generated function body
+ - `strict` When set to `true`, generated function is in strict mode
+ - `_with` Whether or not to use `with() {}` constructs. If `false`
+ then the locals will be stored in the `locals` object. Set to `false` in strict mode.
+ - `destructuredLocals` An array of local variables that are always destructured from
+ the locals object, available even in strict mode.
+ - `localsName` Name to use for the object storing local variables when not using
+ `with` Defaults to `locals`
+ - `rmWhitespace` Remove all safe-to-remove whitespace, including leading
+ and trailing whitespace. It also enables a safer version of `-%>` line
+ slurping for all scriptlet tags (it does not strip new lines of tags in
+ the middle of a line).
+ - `escape` The escaping function used with `<%=` construct. It is
+ used in rendering and is `.toString()`ed in the generation of client functions.
+ (By default escapes XML).
+ - `outputFunctionName` Set to a string (e.g., 'echo' or 'print') for a function to print
+ output inside scriptlet tags.
+ - `async` When `true`, EJS will use an async function for rendering. (Depends
+ on async/await support in the JS runtime.
+
+This project uses [JSDoc](http://usejsdoc.org/). For the full public API
+documentation, clone the repository and run `npm run doc`. This will run JSDoc
+with the proper options and output the documentation to `out/`. If you want
+the both the public & private API docs, run `npm run devdoc` instead.
+
+## Tags
+
+ - `<%` 'Scriptlet' tag, for control-flow, no output
+ - `<%_` 'Whitespace Slurping' Scriptlet tag, strips all whitespace before it
+ - `<%=` Outputs the value into the template (escaped)
+ - `<%-` Outputs the unescaped value into the template
+ - `<%#` Comment tag, no execution, no output
+ - `<%%` Outputs a literal '<%'
+ - `%%>` Outputs a literal '%>'
+ - `%>` Plain ending tag
+ - `-%>` Trim-mode ('newline slurp') tag, trims following newline
+ - `_%>` 'Whitespace Slurping' ending tag, removes all whitespace after it
+
+For the full syntax documentation, please see [docs/syntax.md](https://github.com/mde/ejs/blob/master/docs/syntax.md).
+
+## Includes
+
+Includes either have to be an absolute path, or, if not, are assumed as
+relative to the template with the `include` call. For example if you are
+including `./views/user/show.ejs` from `./views/users.ejs` you would
+use `<%- include('user/show') %>`.
+
+You must specify the `filename` option for the template with the `include`
+call unless you are using `renderFile()`.
+
+You'll likely want to use the raw output tag (`<%-`) with your include to avoid
+double-escaping the HTML output.
+
+```ejs
+<ul>
+ <% users.forEach(function(user){ %>
+ <%- include('user/show', {user: user}) %>
+ <% }); %>
+</ul>
+```
+
+Includes are inserted at runtime, so you can use variables for the path in the
+`include` call (for example `<%- include(somePath) %>`). Variables in your
+top-level data object are available to all your includes, but local variables
+need to be passed down.
+
+NOTE: Include preprocessor directives (`<% include user/show %>`) are
+still supported.
+
+## Custom delimiters
+
+Custom delimiters can be applied on a per-template basis, or globally:
+
+```javascript
+let ejs = require('ejs'),
+ users = ['geddy', 'neil', 'alex'];
+
+// Just one template
+ejs.render('<?= users.join(" | "); ?>', {users: users}, {delimiter: '?'});
+// => 'geddy | neil | alex'
+
+// Or globally
+ejs.delimiter = '$';
+ejs.render('<$= users.join(" | "); $>', {users: users});
+// => 'geddy | neil | alex'
+```
+
+## Caching
+
+EJS ships with a basic in-process cache for caching the intermediate JavaScript
+functions used to render templates. It's easy to plug in LRU caching using
+Node's `lru-cache` library:
+
+```javascript
+let ejs = require('ejs'),
+ LRU = require('lru-cache');
+ejs.cache = LRU(100); // LRU cache with 100-item limit
+```
+
+If you want to clear the EJS cache, call `ejs.clearCache`. If you're using the
+LRU cache and need a different limit, simple reset `ejs.cache` to a new instance
+of the LRU.
+
+## Custom file loader
+
+The default file loader is `fs.readFileSync`, if you want to customize it, you can set ejs.fileLoader.
+
+```javascript
+let ejs = require('ejs');
+let myFileLoad = function (filePath) {
+ return 'myFileLoad: ' + fs.readFileSync(filePath);
+};
+
+ejs.fileLoader = myFileLoad;
+```
+
+With this feature, you can preprocess the template before reading it.
+
+## Layouts
+
+EJS does not specifically support blocks, but layouts can be implemented by
+including headers and footers, like so:
+
+
+```ejs
+<%- include('header') -%>
+<h1>
+ Title
+</h1>
+<p>
+ My page
+</p>
+<%- include('footer') -%>
+```
+
+## Client-side support
+
+Go to the [Latest Release](https://github.com/mde/ejs/releases/latest), download
+`./ejs.js` or `./ejs.min.js`. Alternately, you can compile it yourself by cloning
+the repository and running `jake build` (or `$(npm bin)/jake build` if jake is
+not installed globally).
+
+Include one of these files on your page, and `ejs` should be available globally.
+
+### Example
+
+```html
+<div id="output"></div>
+<script src="ejs.min.js"></script>
+<script>
+ let people = ['geddy', 'neil', 'alex'],
+ html = ejs.render('<%= people.join(", "); %>', {people: people});
+ // With jQuery:
+ $('#output').html(html);
+ // Vanilla JS:
+ document.getElementById('output').innerHTML = html;
+</script>
+```
+
+### Caveats
+
+Most of EJS will work as expected; however, there are a few things to note:
+
+1. Obviously, since you do not have access to the filesystem, `ejs.renderFile()` won't work.
+2. For the same reason, `include`s do not work unless you use an `include callback`. Here is an example:
+ ```javascript
+ let str = "Hello <%= include('file', {person: 'John'}); %>",
+ fn = ejs.compile(str, {client: true});
+
+ fn(data, null, function(path, d){ // include callback
+ // path -> 'file'
+ // d -> {person: 'John'}
+ // Put your code here
+ // Return the contents of file as a string
+ }); // returns rendered string
+ ```
+
+See the [examples folder](https://github.com/mde/ejs/tree/master/examples) for more details.

+# Engine.IO client
+
+[](http://travis-ci.org/socketio/engine.io-client)
+[](http://badge.fury.io/js/engine.io-client)
+
+This is the client for [Engine.IO](http://github.com/socketio/engine.io),
+the implementation of transport-based cross-browser/cross-device
+bi-directional communication layer for [Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Standalone
+
+You can find an `engine.io.js` file in this repository, which is a
+standalone build you can use as follows:
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+ // eio = Socket
+ var socket = eio('ws://localhost');
+ socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+ });
+</script>
+```
+
+### With browserify
+
+Engine.IO is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the client package
+
+ ```bash
+ $ npm install engine.io-client
+ ```
+
+1. write your app code
+
+ ```js
+ var socket = require('engine.io-client')('ws://localhost');
+ socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+ });
+ ```
+
+1. build your app bundle
+
+ ```bash
+ $ browserify app.js > bundle.js
+ ```
+
+1. include on your page
+
+ ```html
+ <script src="/path/to/bundle.js"></script>
+ ```
+
+### Sending and receiving binary
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+ var socket = new eio.Socket('ws://localhost/');
+ socket.binaryType = 'blob';
+ socket.on('open', function () {
+ socket.send(new Int8Array(5));
+ socket.on('message', function(blob){});
+ socket.on('close', function(){ });
+ });
+</script>
+```
+
+### Node.JS
+
+Add `engine.io-client` to your `package.json` and then:
+
+```js
+var socket = require('engine.io-client')('ws://localhost');
+socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+});
+```
+
+### Node.js with certificates
+```js
+var opts = {
+ key: fs.readFileSync('test/fixtures/client.key'),
+ cert: fs.readFileSync('test/fixtures/client.crt'),
+ ca: fs.readFileSync('test/fixtures/ca.crt')
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+});
+```
+
+### Node.js with extraHeaders
+```js
+var opts = {
+ extraHeaders: {
+ 'X-Custom-Header-For-My-Project': 'my-secret-access-token',
+ 'Cookie': 'user_session=NI2JlCKF90aE0sJZD9ZzujtdsUqNYSBYxzlTsvdSUe35ZzdtVRGqYFr0kdGxbfc5gUOkR9RGp20GVKza; path=/; expires=Tue, 07-Apr-2015 18:18:08 GMT; secure; HttpOnly'
+ }
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+});
+```
+
+## Features
+
+- Lightweight
+- Runs on browser and node.js seamlessly
+- Transports are independent of `Engine`
+ - Easy to debug
+ - Easy to unit test
+- Runs inside HTML5 WebWorker
+- Can send and receive binary data
+ - Receives as ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer
+ in Node
+ - When XHR2 or WebSockets are used, binary is emitted directly. Otherwise
+ binary is encoded into base64 strings, and decoded when binary types are
+ supported.
+ - With browsers that don't support ArrayBuffer, an object { base64: true,
+ data: dataAsBase64String } is emitted on the `message` event.
+
+## API
+
+### Socket
+
+The client class. Mixes in [Emitter](http://github.com/component/emitter).
+Exposed as `eio` in the browser standalone build.
+
+#### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `binaryType` _(String)_ : can be set to 'arraybuffer' or 'blob' in browsers,
+ and `buffer` or `arraybuffer` in Node. Blob is only used in browser if it's
+ supported.
+
+#### Events
+
+- `open`
+ - Fired upon successful connection.
+- `message`
+ - Fired when data is received from the server.
+ - **Arguments**
+ - `String` | `ArrayBuffer`: utf-8 encoded data or ArrayBuffer containing
+ binary data
+- `close`
+ - Fired upon disconnection. In compliance with the WebSocket API spec, this event may be
+ fired even if the `open` event does not occur (i.e. due to connection error or `close()`).
+- `error`
+ - Fired when an error occurs.
+- `flush`
+ - Fired upon completing a buffer flush
+- `drain`
+ - Fired after `drain` event of transport if writeBuffer is empty
+- `upgradeError`
+ - Fired if an error occurs with a transport we're trying to upgrade to.
+- `upgrade`
+ - Fired upon upgrade success, after the new transport is set
+- `ping`
+ - Fired upon _flushing_ a ping packet (ie: actual packet write out)
+- `pong`
+ - Fired upon receiving a pong packet.
+
+#### Methods
+
+- **constructor**
+ - Initializes the client
+ - **Parameters**
+ - `String` uri
+ - `Object`: optional, options object
+ - **Options**
+ - `agent` (`http.Agent`): `http.Agent` to use, defaults to `false` (NodeJS only)
+ - `upgrade` (`Boolean`): defaults to true, whether the client should try
+ to upgrade the transport from long-polling to something better.
+ - `forceJSONP` (`Boolean`): forces JSONP for polling transport.
+ - `jsonp` (`Boolean`): determines whether to use JSONP when
+ necessary for polling. If disabled (by settings to false) an error will
+ be emitted (saying "No transports available") if no other transports
+ are available. If another transport is available for opening a
+ connection (e.g. WebSocket) that transport
+ will be used instead.
+ - `forceBase64` (`Boolean`): forces base 64 encoding for polling transport even when XHR2 responseType is available and WebSocket even if the used standard supports binary.
+ - `enablesXDR` (`Boolean`): enables XDomainRequest for IE8 to avoid loading bar flashing with click sound. default to `false` because XDomainRequest has a flaw of not sending cookie.
+ - `withCredentials` (`Boolean`): defaults to `true`, whether to include credentials (cookies, authorization headers, TLS client certificates, etc.) with cross-origin XHR polling requests.
+ - `timestampRequests` (`Boolean`): whether to add the timestamp with each
+ transport request. Note: polling requests are always stamped unless this
+ option is explicitly set to `false` (`false`)
+ - `timestampParam` (`String`): timestamp parameter (`t`)
+ - `policyPort` (`Number`): port the policy server listens on (`843`)
+ - `path` (`String`): path to connect to, default is `/engine.io`
+ - `transports` (`Array`): a list of transports to try (in order).
+ Defaults to `['polling', 'websocket']`. `Engine`
+ always attempts to connect directly with the first one, provided the
+ feature detection test for it passes.
+ - `transportOptions` (`Object`): hash of options, indexed by transport name, overriding the common options for the given transport
+ - `rememberUpgrade` (`Boolean`): defaults to false.
+ If true and if the previous websocket connection to the server succeeded,
+ the connection attempt will bypass the normal upgrade process and will initially
+ try websocket. A connection attempt following a transport error will use the
+ normal upgrade process. It is recommended you turn this on only when using
+ SSL/TLS connections, or if you know that your network does not block websockets.
+ - `pfx` (`String`|`Buffer`): Certificate, Private key and CA certificates to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+ - `key` (`String`): Private key to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+ - `passphrase` (`String`): A string of passphrase for the private key or pfx. Can be used in Node.js client environment to manually specify certificate information.
+ - `cert` (`String`): Public x509 certificate to use. Can be used in Node.js client environment to manually specify certificate information.
+ - `ca` (`String`|`Array`): An authority certificate or array of authority certificates to check the remote host against.. Can be used in Node.js client environment to manually specify certificate information.
+ - `ciphers` (`String`): A string describing the ciphers to use or exclude. Consult the [cipher format list](http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT) for details on the format. Can be used in Node.js client environment to manually specify certificate information.
+ - `rejectUnauthorized` (`Boolean`): If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. Can be used in Node.js client environment to manually specify certificate information.
+ - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+ (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
+ - `threshold` (`Number`): data is compressed only if the byte size is above this value. This option is ignored on the browser. (`1024`)
+ - `extraHeaders` (`Object`): Headers that will be passed for each request to the server (via xhr-polling and via websockets). These values then can be used during handshake or for special proxies. Can only be used in Node.js client environment.
+ - `onlyBinaryUpgrades` (`Boolean`): whether transport upgrades should be restricted to transports supporting binary data (`false`)
+ - `forceNode` (`Boolean`): Uses NodeJS implementation for websockets - even if there is a native Browser-Websocket available, which is preferred by default over the NodeJS implementation. (This is useful when using hybrid platforms like nw.js or electron) (`false`, NodeJS only)
+ - `localAddress` (`String`): the local IP address to connect to
+ - **Polling-only options**
+ - `requestTimeout` (`Number`): Timeout for xhr-polling requests in milliseconds (`0`)
+ - **Websocket-only options**
+ - `protocols` (`Array`): a list of subprotocols (see [MDN reference](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Subprotocols))
+- `send`
+ - Sends a message to the server
+ - **Parameters**
+ - `String` | `ArrayBuffer` | `ArrayBufferView` | `Blob`: data to send
+ - `Object`: optional, options object
+ - `Function`: optional, callback upon `drain`
+ - **Options**
+ - `compress` (`Boolean`): whether to compress sending data. This option is ignored and forced to be `true` on the browser. (`true`)
+- `close`
+ - Disconnects the client.
+
+### Transport
+
+The transport class. Private. _Inherits from EventEmitter_.
+
+#### Events
+
+- `poll`: emitted by polling transports upon starting a new request
+- `pollComplete`: emitted by polling transports upon completing a request
+- `drain`: emitted by polling transports upon a buffer drain
+
+## Tests
+
+`engine.io-client` is used to test
+[engine](http://github.com/socketio/engine.io). Running the `engine.io`
+test suite ensures the client works and vice-versa.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul). You can
+run the tests locally using the following command.
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+Additionally, `engine.io-client` has a standalone test suite you can run
+with `make test` which will run node.js and browser tests. You must have zuul setup with
+a saucelabs account.
+
+## Support
+
+The support channels for `engine.io-client` are the same as `socket.io`:
+ - irc.freenode.net **#socket.io**
+ - [Google Groups](http://groups.google.com/group/socket_io)
+ - [Website](http://socket.io)
+
+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:

+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">

+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.

+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+

+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://spectrum.chat/zeit)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+ms('-3 days') // -259200000
+ms('-1h') // -3600000
+ms('-200') // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(-3 * 60000) // "-3m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(-3 * 60000, { long: true }) // "-3 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# ws: a Node.js WebSocket library
+
+[](https://www.npmjs.com/package/ws)
+[](https://travis-ci.org/websockets/ws)
+[](https://ci.appveyor.com/project/lpinca/ws)
+[](https://coveralls.io/r/websockets/ws?branch=master)
+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
+server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
+object. To make the same code work seamlessly on Node.js and the browser, you
+can use one of the many wrappers available on npm, like
+[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

+## Protocol support
+
+- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+- **HyBi drafts 13-17** (Current default, alternatively option
+ `protocolVersion: 13`)
+
+## Installing
+
+```
+npm install ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+ operations such as masking and unmasking the data payload of the WebSocket
+ frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
+ message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like docs for the ws classes.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which enables
+the client and server to negotiate a compression algorithm and its parameters,
+and then selectively apply it to the data payloads of each WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on the
+client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+Note that Node.js has a variety of issues with high-performance compression,
+where increased concurrency, especially on Linux, can lead to [catastrophic
+memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
+permessage-deflate in production, it is worthwhile to set up a test
+representative of your workload and ensure Node.js/zlib will handle it with
+acceptable performance and memory usage.
+
+Tuning of permessage-deflate can be done via the options defined below. You can
+also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
+into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
+
+See [the docs][ws-server-options] for more options.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({
+ port: 8080,
+ perMessageDeflate: {
+ zlibDeflateOptions: {
+ // See zlib defaults.
+ chunkSize: 1024,
+ memLevel: 7,
+ level: 3
+ },
+ zlibInflateOptions: {
+ chunkSize: 10 * 1024
+ },
+ // Other options settable:
+ clientNoContextTakeover: true, // Defaults to negotiated value.
+ serverNoContextTakeover: true, // Defaults to negotiated value.
+ serverMaxWindowBits: 10, // Defaults to negotiated value.
+ // Below options specified as default values.
+ concurrencyLimit: 10, // Limits zlib concurrency for perf.
+ threshold: 1024 // Size (in bytes) below which messages
+ // should not be compressed.
+ }
+});
+```
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+ perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+ console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ const array = new Float32Array(5);
+
+ for (var i = 0; i < array.length; ++i) {
+ array[i] = i / 2;
+ }
+
+ ws.send(array);
+});
+```
+
+### Simple server
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+```
+
+### External HTTP/S server
+
+```js
+const fs = require('fs');
+const https = require('https');
+const WebSocket = require('ws');
+
+const server = new https.createServer({
+ cert: fs.readFileSync('/path/to/cert.pem'),
+ key: fs.readFileSync('/path/to/key.pem')
+});
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+
+server.listen(8080);
+```
+
+### Multiple servers sharing a single HTTP/S server
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+
+const server = http.createServer();
+const wss1 = new WebSocket.Server({ noServer: true });
+const wss2 = new WebSocket.Server({ noServer: true });
+
+wss1.on('connection', function connection(ws) {
+ // ...
+});
+
+wss2.on('connection', function connection(ws) {
+ // ...
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+ const pathname = url.parse(request.url).pathname;
+
+ if (pathname === '/foo') {
+ wss1.handleUpgrade(request, socket, head, function done(ws) {
+ wss1.emit('connection', ws, request);
+ });
+ } else if (pathname === '/bar') {
+ wss2.handleUpgrade(request, socket, head, function done(ws) {
+ wss2.emit('connection', ws, request);
+ });
+ } else {
+ socket.destroy();
+ }
+});
+
+server.listen(8080);
+```
+
+### Server broadcast
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+// Broadcast to all.
+wss.broadcast = function broadcast(data) {
+ wss.clients.forEach(function each(client) {
+ if (client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+};
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(data) {
+ // Broadcast to everyone else.
+ wss.clients.forEach(function each(client) {
+ if (client !== ws && client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+ });
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+ origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+ console.log('connected');
+ ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+ console.log('disconnected');
+});
+
+ws.on('message', function incoming(data) {
+ console.log(`Roundtrip time: ${Date.now() - data} ms`);
+
+ setTimeout(function timeout() {
+ ws.send(Date.now());
+ }, 500);
+});
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## Error handling best practices
+
+```js
+// If the WebSocket is closed before the following send is attempted
+ws.send('something');
+
+// Errors (both immediate and async write errors) can be detected in an optional
+// callback. The callback is also the only way of being notified that data has
+// actually been sent.
+ws.send('something', function ack(error) {
+ // If error is not defined, the send has been completed, otherwise the error
+ // object will indicate what failed.
+});
+
+// Immediate errors can also be handled with `try...catch`, but **note** that
+// since sends are inherently asynchronous, socket write failures will *not* be
+// captured when this technique is used.
+try {
+ ws.send('something');
+} catch (e) {
+ /* handle error */
+}
+```
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+ const ip = req.connection.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+ const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a way
+that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+function noop() {}
+
+function heartbeat() {
+ this.isAlive = true;
+}
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.isAlive = true;
+ ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+ wss.clients.forEach(function each(ws) {
+ if (ws.isAlive === false) return ws.terminate();
+
+ ws.isAlive = false;
+ ws.ping(noop);
+ });
+}, 30000);
+```
+
+Pong messages are automatically sent in response to ping messages as required by
+the spec.
+
+Just like the server example above your clients might as well lose connection
+without knowing it. You might want to add a ping listener on your clients to
+prevent that. A simple implementation would be:
+
+```js
+const WebSocket = require('ws');
+
+function heartbeat() {
+ clearTimeout(this.pingTimeout);
+
+ // Use `WebSocket#terminate()` and not `WebSocket#close()`. Delay should be
+ // equal to the interval at which your server sends out pings plus a
+ // conservative assumption of the latency.
+ this.pingTimeout = setTimeout(() => {
+ this.terminate();
+ }, 30000 + 1000);
+}
+
+const client = new WebSocket('wss://echo.websocket.org/');
+
+client.on('open', heartbeat);
+client.on('ping', heartbeat);
+client.on('close', function clear() {
+ clearTimeout(this.pingTimeout);
+});
+```
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].

+# engine.io-parser
+
+[](https://travis-ci.org/socketio/engine.io-parser)
+[](https://npmjs.com/package/engine.io-parser)
+
+This is the JavaScript parser for the engine.io protocol encoding,
+shared by both
+[engine.io-client](https://github.com/socketio/engine.io-client) and
+[engine.io](https://github.com/socketio/engine.io).
+
+## How to use
+
+### Standalone
+
+The parser can encode/decode packets, payloads, and payloads as binary
+with the following methods: `encodePacket`, `decodePacket`, `encodePayload`,
+`decodePayload`, `encodePayloadAsBinary`, `decodePayloadAsBinary`.
+
+The browser-side parser also includes `encodePayloadAsArrayBuffer` and `encodePayloadAsBlob`.
+
+Example:
+
+```js
+var parser = require('engine.io-parser');
+
+var data = new Buffer(5);
+for (var i = 0; i < data.length; i++) { data[i] = i; }
+
+parser.encodePacket({ type: 'message', data: data }, function(encoded) {
+ var decodedData = parser.decodePacket(encoded); // { type: 'message', data: data }
+});
+```
+
+### With browserify
+
+Engine.IO Parser is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the parser package
+
+ ```shell
+ npm install engine.io-parser
+ ```
+
+1. write your app code
+
+ ```js
+ var parser = require('engine.io-parser');
+
+ var testBuffer = new Int8Array(10);
+ for (var i = 0; i < testBuffer.length; i++) testBuffer[i] = i;
+
+ var packets = [{ type: 'message', data: testBuffer.buffer }, { type: 'message', data: 'hello' }];
+
+ parser.encodePayload(packets, function(encoded) {
+ parser.decodePayload(encoded,
+ function(packet, index, total) {
+ var isLast = index + 1 == total;
+ if (!isLast) {
+ var buffer = new Int8Array(packet.data); // testBuffer
+ } else {
+ var message = packet.data; // 'hello'
+ }
+ });
+ });
+ ```
+
+1. build your app bundle
+
+ ```bash
+ $ browserify app.js > bundle.js
+ ```
+
+1. include on your page
+
+ ```html
+ <script src="/path/to/bundle.js"></script>
+ ```
+
+## Features
+
+- Runs on browser and node.js seamlessly
+- Runs inside HTML5 WebWorker
+- Can encode and decode packets
+ - Encodes from/to ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer in Node
+
+## API
+
+Note: `cb(type)` means the type is a callback function that contains a parameter of type `type` when called.
+
+### Node
+
+- `encodePacket`
+ - Encodes a packet.
+ - **Parameters**
+ - `Object`: the packet to encode, has `type` and `data`.
+ - `data`: can be a `String`, `Number`, `Buffer`, `ArrayBuffer`
+ - `Boolean`: optional, binary support
+ - `Function`: callback, returns the encoded packet (`cb(String)`)
+- `decodePacket`
+ - Decodes a packet. Data also available as an ArrayBuffer if requested.
+ - Returns data as `String` or (`Blob` on browser, `ArrayBuffer` on Node)
+ - **Parameters**
+ - `String` | `ArrayBuffer`: the packet to decode, has `type` and `data`
+ - `String`: optional, the binary type
+
+- `encodeBase64Packet`
+ - Encodes a packet with binary data in a base64 string (`String`)
+ - **Parameters**
+ - `Object`: the packet to encode, has `type` and `data`
+ - `Function`: callback, returns the base64 encoded message (`cb(String)`)
+- `decodeBase64Packet`
+ - Decodes a packet encoded in a base64 string.
+ - **Parameters**
+ - `String`: the base64 encoded message
+ - `String`: optional, the binary type
+
+- `encodePayload`
+ - Encodes multiple messages (payload).
+ - If any contents are binary, they will be encoded as base64 strings. Base64
+ encoded strings are marked with a b before the length specifier
+ - **Parameters**
+ - `Array`: an array of packets
+ - `Boolean`: optional, binary support
+ - `Function`: callback, returns the encoded payload (`cb(String)`)
+- `decodePayload`
+ - Decodes data when a payload is maybe expected. Possible binary contents are
+ decoded from their base64 representation.
+ - **Parameters**
+ - `String`: the payload
+ - `String`: optional, the binary type
+ - `Function`: callback, returns (cb(`Object`: packet, `Number`:packet index, `Number`:packet total))
+
+- `encodePayloadAsBinary`
+ - Encodes multiple messages (payload) as binary.
+ - **Parameters**
+ - `Array`: an array of packets
+ - `Function`: callback, returns the encoded payload (`cb(Buffer)`)
+- `decodePayloadAsBinary`
+ - Decodes data when a payload is maybe expected. Strings are decoded by
+ interpreting each byte as a key code for entries marked to start with 0. See
+ description of encodePayloadAsBinary.
+ - **Parameters**
+ - `Buffer`: the buffer
+ - `String`: optional, the binary type
+ - `Function`: callback, returns the decoded packet (`cb(Object)`)
+
+### Browser
+
+- `encodePayloadAsArrayBuffer`
+ - Encodes multiple messages (payload) as binary.
+ - **Parameters**
+ - `Array`: an array of packets
+ - `Function`: callback, returns the encoded payload (`cb(ArrayBuffer)`)
+- `encodePayloadAsBlob`
+ - Encodes multiple messages (payload) as blob.
+ - **Parameters**
+ - `Array`: an array of packets
+ - `Function`: callback, returns the encoded payload (`cb(Blob)`)
+
+## Tests
+
+Standalone tests can be run with `make test` which will run both node.js and browser tests.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul).
+(You must have zuul setup with a saucelabs account.)
+
+You can run the tests locally using the following command:
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+## Support
+
+The support channels for `engine.io-parser` are the same as `socket.io`:
+ - irc.freenode.net **#socket.io**
+ - [Google Groups](http://groups.google.com/group/socket_io)
+ - [Website](http://socket.io)
+

+# Engine.IO: the realtime engine
+
+[](http://travis-ci.org/socketio/engine.io)
+[](http://badge.fury.io/js/engine.io)
+
+`Engine.IO` is the implementation of transport-based
+cross-browser/cross-device bi-directional communication layer for
+[Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Server
+
+#### (A) Listening on a port
+
+```js
+var engine = require('engine.io');
+var server = engine.listen(80);
+
+server.on('connection', function(socket){
+ socket.send('utf 8 string');
+ socket.send(Buffer.from([0, 1, 2, 3, 4, 5])); // binary data
+});
+```
+
+#### (B) Intercepting requests for a http.Server
+
+```js
+var engine = require('engine.io');
+var http = require('http').createServer().listen(3000);
+var server = engine.attach(http);
+
+server.on('connection', function (socket) {
+ socket.on('message', function(data){ });
+ socket.on('close', function(){ });
+});
+```
+
+#### (C) Passing in requests
+
+```js
+var engine = require('engine.io');
+var server = new engine.Server();
+
+server.on('connection', function(socket){
+ socket.send('hi');
+});
+
+// …
+httpServer.on('upgrade', function(req, socket, head){
+ server.handleUpgrade(req, socket, head);
+});
+httpServer.on('request', function(req, res){
+ server.handleRequest(req, res);
+});
+```
+
+### Client
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+ var socket = new eio.Socket('ws://localhost/');
+ socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+ });
+</script>
+```
+

+
+## API
+
+### Server
+
+<hr><br>
+
+#### Top-level
+
+These are exposed by `require('engine.io')`:
+
+##### Events
+
+- `flush`
+ - Called when a socket buffer is being flushed.
+ - **Arguments**
+ - `Socket`: socket being flushed
+ - `Array`: write buffer
+- `drain`
+ - Called when a socket buffer is drained
+ - **Arguments**
+ - `Socket`: socket being flushed
+
+##### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `Server`: Server class constructor
+- `Socket`: Socket class constructor
+- `Transport` _(Function)_: transport constructor
+- `transports` _(Object)_: map of available transports
+
+##### Methods
+
+- `()`
+ - Returns a new `Server` instance. If the first argument is an `http.Server` then the
+ new `Server` instance will be attached to it. Otherwise, the arguments are passed
+ directly to the `Server` constructor.
+ - **Parameters**
+ - `http.Server`: optional, server to attach to.
+ - `Object`: optional, options object (see `Server#constructor` api docs below)
+
+ The following are identical ways to instantiate a server and then attach it.
+
+```js
+var httpServer; // previously created with `http.createServer();` from node.js api.
+
+// create a server first, and then attach
+var eioServer = require('engine.io').Server();
+eioServer.attach(httpServer);
+
+// or call the module as a function to get `Server`
+var eioServer = require('engine.io')();
+eioServer.attach(httpServer);
+
+// immediately attach
+var eioServer = require('engine.io')(httpServer);
+
+// with custom options
+var eioServer = require('engine.io')(httpServer, {
+ maxHttpBufferSize: 1e3
+});
+```
+
+- `listen`
+ - Creates an `http.Server` which listens on the given port and attaches WS
+ to it. It returns `501 Not Implemented` for regular http requests.
+ - **Parameters**
+ - `Number`: port to listen on.
+ - `Object`: optional, options object
+ - `Function`: callback for `listen`.
+ - **Options**
+ - All options from `Server.attach` method, documented below.
+ - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+ - **Returns** `Server`
+
+```js
+var engine = require('engine.io');
+var server = engine.listen(3000, {
+ pingTimeout: 2000,
+ pingInterval: 10000
+});
+
+server.on('connection', /* ... */);
+```
+
+- `attach`
+ - Captures `upgrade` requests for a `http.Server`. In other words, makes
+ a regular http.Server WebSocket-compatible.
+ - **Parameters**
+ - `http.Server`: server to attach to.
+ - `Object`: optional, options object
+ - **Options**
+ - All options from `Server.attach` method, documented below.
+ - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+ - **Returns** `Server` a new Server instance.
+
+```js
+var engine = require('engine.io');
+var httpServer = require('http').createServer().listen(3000);
+var server = engine.attach(httpServer, {
+ wsEngine: 'uws' // requires having uws as dependency
+});
+
+server.on('connection', /* ... */);
+```
+
+#### Server
+
+The main server/manager. _Inherits from EventEmitter_.
+
+##### Events
+
+- `connection`
+ - Fired when a new connection is established.
+ - **Arguments**
+ - `Socket`: a Socket object
+
+##### Properties
+
+**Important**: if you plan to use Engine.IO in a scalable way, please
+keep in mind the properties below will only reflect the clients connected
+to a single process.
+
+- `clients` _(Object)_: hash of connected clients by id.
+- `clientsCount` _(Number)_: number of connected clients.
+
+##### Methods
+
+- **constructor**
+ - Initializes the server
+ - **Parameters**
+ - `Object`: optional, options object
+ - **Options**
+ - `pingTimeout` (`Number`): how many ms without a pong packet to
+ consider the connection closed (`5000`)
+ - `pingInterval` (`Number`): how many ms before sending a new ping
+ packet (`25000`)
+ - `upgradeTimeout` (`Number`): how many ms before an uncompleted transport upgrade is cancelled (`10000`)
+ - `maxHttpBufferSize` (`Number`): how many bytes or characters a message
+ can be, before closing the session (to avoid DoS). Default
+ value is `10E7`.
+ - `allowRequest` (`Function`): A function that receives a given handshake
+ or upgrade request as its first parameter, and can decide whether to
+ continue or not. The second argument is a function that needs to be
+ called with the decided information: `fn(err, success)`, where
+ `success` is a boolean value where false means that the request is
+ rejected, and err is an error code.
+ - `transports` (`<Array> String`): transports to allow connections
+ to (`['polling', 'websocket']`)
+ - `allowUpgrades` (`Boolean`): whether to allow transport upgrades
+ (`true`)
+ - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+ (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
+ - `threshold` (`Number`): data is compressed only if the byte size is above this value (`1024`)
+ - `httpCompression` (`Object|Boolean`): parameters of the http compression for the polling transports
+ (see [zlib](http://nodejs.org/api/zlib.html#zlib_options) api docs). Set to `false` to disable. (`true`)

+ - `cookie` (`String|Boolean`): name of the HTTP cookie that
+ contains the client sid to send as part of handshake response
+ headers. Set to `false` to not send one. (`io`)
+ - `cookiePath` (`String|Boolean`): path of the above `cookie`
+ option. If false, no path will be sent, which means browsers will only send the cookie on the engine.io attached path (`/engine.io`).
+ Set false to not save io cookie on all requests. (`/`)
+ - `cookieHttpOnly` (`Boolean`): If `true` HttpOnly io cookie cannot be accessed by client-side APIs, such as JavaScript. (`true`) _This option has no effect if `cookie` or `cookiePath` is set to `false`._
+ - `wsEngine` (`String`): what WebSocket server implementation to use. Specified module must conform to the `ws` interface (see [ws module api docs](https://github.com/websockets/ws/blob/master/doc/ws.md)). Default value is `ws`. An alternative c++ addon is also available by installing `uws` module.
+ - `initialPacket` (`Object`): an optional packet which will be concatenated to the handshake packet emitted by Engine.IO.
+- `close`
+ - Closes all clients
+ - **Returns** `Server` for chaining
+- `handleRequest`
+ - Called internally when a `Engine` request is intercepted.
+ - **Parameters**

+ - `Object`: optional, options object
+ - **Options**
+ - `path` (`String`): name of the path to capture (`/engine.io`).
+ - `destroyUpgrade` (`Boolean`): destroy unhandled upgrade requests (`true`)
+ - `destroyUpgradeTimeout` (`Number`): milliseconds after which unhandled requests are ended (`1000`)
+ - `handlePreflightRequest` (`Boolean|Function`): whether to let engine.io handle the OPTIONS requests. You can also pass a custom function to handle the requests (`true`)
+- `generateId`
+ - Generate a socket id.
+ - Overwrite this method to generate your custom socket id.
+ - **Parameters**
+ - `http.IncomingMessage`: a node request object

+### Client
+
+<hr><br>
+
+Exposed in the `eio` global namespace (in the browser), or by
+`require('engine.io-client')` (in Node.JS).
+
+For the client API refer to the
+[engine-client](http://github.com/learnboost/engine.io-client) repository.
+
+## Debug / logging
+
+Engine.IO is powered by [debug](http://github.com/visionmedia/debug).
+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Engine.IO's debugging scopes you can use:
+
+```
+DEBUG=engine* node myapp
+```
+
+## Transports
+
+- `polling`: XHR / JSONP polling transport.
+- `websocket`: WebSocket transport.
+
+## Plugins
+
+- [engine.io-conflation](https://github.com/EugenDueck/engine.io-conflation): Makes **conflation and aggregation** of messages straightforward.
+
+## Support
+
+The support channels for `engine.io` are the same as `socket.io`:
+ - irc.freenode.net **#socket.io**
+ - [Google Groups](http://groups.google.com/group/socket_io)
+ - [Website](http://socket.io)
+
+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:
+
+```
+git clone git://github.com/LearnBoost/engine.io.git
+```
+
+Then:
+
+```
+cd engine.io
+npm install
+```
+
+## Tests
+
+Tests run with `npm test`. It runs the server tests that are aided by
+the usage of `engine.io-client`.
+
+Make sure `npm install` is run first.
+
+## Goals
+
+The main goal of `Engine` is ensuring the most reliable realtime communication.
+Unlike the previous Socket.IO core, it always establishes a long-polling
+connection first, then tries to upgrade to better transports that are "tested" on
+the side.
+
+During the lifetime of the Socket.IO projects, we've found countless drawbacks
+to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection
+mechanisms.
+
+Both are clearly the _right way_ of establishing a bidirectional communication,
+with HTML5 WebSocket being the way of the future. However, to answer most business
+needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering
+the same solution.
+
+WebSocket based connections have two fundamental benefits:
+
+1. **Better server performance**
+ - _A: Load balancers_<br>
+ Load balancing a long polling connection poses a serious architectural nightmare
+ since requests can come from any number of open sockets by the user agent, but
+ they all need to be routed to the process and computer that owns the `Engine`
+ connection. This negatively impacts RAM and CPU usage.
+ - _B: Network traffic_<br>
+ WebSocket is designed around the premise that each message frame has to be
+ surrounded by the least amount of data. In HTTP 1.1 transports, each message
+ frame is surrounded by HTTP headers and chunked encoding frames. If you try to
+ send the message _"Hello world"_ with xhr-polling, the message ultimately
+ becomes larger than if you were to send it with WebSocket.
+ - _C: Lightweight parser_<br>
+ As an effect of **B**, the server has to do a lot more work to parse the network
+ data and figure out the message when traditional HTTP requests are used
+ (as in long polling). This means that another advantage of WebSocket is
+ less server CPU usage.
+
+2. **Better user experience**
+
+ Due to the reasons stated in point **1**, the most important effect of being able
+ to establish a WebSocket connection is raw data transfer speed, which translates
+ in _some_ cases in better user experience.
+
+ Applications with heavy realtime interaction (such as games) will benefit greatly,
+ whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or
+ timelines (Twitter) will have negligible user experience improvements.
+
+Having said this, attempting to establish a WebSocket connection directly so far has
+proven problematic:
+
+1. **Proxies**<br>
+ Many corporate proxies block WebSocket traffic.
+
+2. **Personal firewall and antivirus software**<br>
+ As a result of our research, we've found that at least 3 personal security
+ applications block WebSocket traffic.
+
+3. **Cloud application platforms**<br>
+ Platforms like Heroku or No.de have had trouble keeping up with the fast-paced
+ nature of the evolution of the WebSocket protocol. Applications therefore end up
+ inevitably using long polling, but the seamless installation experience of
+ Socket.IO we strive for (_"require() it and it just works"_) disappears.
+
+Some of these problems have solutions. In the case of proxies and personal programs,
+however, the solutions many times involve upgrading software. Experience has shown
+that relying on client software upgrades to deliver a business solution is
+fruitless: the very existence of this project has to do with a fragmented panorama
+of user agent distribution, with clients connecting with latest versions of the most
+modern user agents (Chrome, Firefox and Safari), but others with versions as low as
+IE 5.5.
+
+From the user perspective, an unsuccessful WebSocket connection can translate in
+up to at least 10 seconds of waiting for the realtime application to begin
+exchanging data. This **perceptively** hurts user experience.
+
+To summarize, **Engine** focuses on reliability and user experience first, marginal
+potential UX improvements and increased server performance second. `Engine` is the
+result of all the lessons learned with WebSocket in the wild.
+
+## Architecture
+
+The main premise of `Engine`, and the core of its existence, is the ability to
+swap transports on the fly. A connection starts as xhr-polling, but it can
+switch to WebSocket.
+
+The central problem this poses is: how do we switch transports without losing
+messages?
+
+`Engine` only switches from polling to another transport in between polling
+cycles. Since the server closes the connection after a certain timeout when
+there's no activity, and the polling transport implementation buffers messages
+in between connections, this ensures no message loss and optimal performance.
+
+Another benefit of this design is that we workaround almost all the limitations
+of **Flash Socket**, such as slow connection times, increased file size (we can
+safely lazy load it without hurting user experience), etc.
+
+## FAQ
+
+### Can I use engine without Socket.IO ?
+
+Absolutely. Although the recommended framework for building realtime applications
+is Socket.IO, since it provides fundamental features for real-world applications
+such as multiplexing, reconnection support, etc.
+
+`Engine` is to Socket.IO what Connect is to Express. An essential piece for building
+realtime frameworks, but something you _probably_ won't be using for building
+actual applications.
+
+### Does the server serve the client?
+
+No. The main reason is that `Engine` is meant to be bundled with frameworks.
+Socket.IO includes `Engine`, therefore serving two clients is not necessary. If
+you use Socket.IO, including
+
+```html
+<script src="/socket.io/socket.io.js">
+```
+
+has you covered.
+
+### Can I implement `Engine` in other languages?
+
+Absolutely. The [engine.io-protocol](https://github.com/LearnBoost/engine.io-protocol)
+repository contains the most up to date description of the specification
+at all times, and the parser implementation in JavaScript.

+
+Basic HTTP cookie parser and serializer for HTTP servers.
+
+## Installation
+
+```sh
+$ npm install cookie
+```
+
+## API
+
+```js
+var cookie = require('cookie');
+```
+
+### cookie.parse(str, options)
+
+Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
+The `str` argument is the string representing a `Cookie` header value and `options` is an
+optional object containing additional parsing options.
+
+```js
+var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
+// { foo: 'bar', equation: 'E=mc^2' }
+```
+
+#### Options
+
+`cookie.parse` accepts these properties in the options object.
+
+##### decode
+
+Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
+has a limited character set (and must be a simple string), this function can be used to decode
+a previously-encoded cookie value into a JavaScript string or other object.
+
+The default function is the global `decodeURIComponent`, which will decode any URL-encoded
+sequences into their byte representations.
+
+**note** if an error is thrown from this function, the original, non-decoded cookie value will
+be returned as the cookie's value.
+
+### cookie.serialize(name, value, options)
+
+Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
+name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
+argument is an optional object containing additional serialization options.
+
+```js
+var setCookie = cookie.serialize('foo', 'bar');
+// foo=bar
+```
+
+#### Options
+
+`cookie.serialize` accepts these properties in the options object.
+
+##### domain
+
+Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6266-5.2.3]. By default, no
+domain is set, and most clients will consider the cookie to apply to only the current domain.
+
+##### encode
+
+Specifies a function that will be used to encode a cookie's value. Since value of a cookie
+has a limited character set (and must be a simple string), this function can be used to encode
+a value into a string suited for a cookie's value.
+
+The default function is the global `ecodeURIComponent`, which will encode a JavaScript string
+into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
+
+##### expires
+
+Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6266-5.2.1].
+By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
+will delete it on a condition like exiting a web browser application.
+
+**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
+`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### httpOnly
+
+Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6266-5.2.6]. When truthy,
+the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not allow client-side
+JavaScript to see the cookie in `document.cookie`.
+
+##### maxAge
+
+Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6266-5.2.2].
+The given number will be converted to an integer by rounding down. By default, no maximum age is set.
+
+**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
+`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### path
+
+Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6266-5.2.4]. By default, the path
+is considered the ["default path"][rfc-6266-5.1.4]. By default, no maximum age is set, and most
+clients will consider this a "non-persistent cookie" and will delete it on a condition like exiting
+a web browser application.
+
+##### sameSite
+
+Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][draft-west-first-party-cookies-07].
+
+ - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+ - `false` will not set the `SameSite` attribute.
+ - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
+ - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+
+More information about the different enforcement levels can be found in the specification
+https://tools.ietf.org/html/draft-west-first-party-cookies-07#section-4.1.1
+
+**note** This is an attribute that has not yet been fully standardized, and may change in the future.
+This also means many clients may ignore this attribute until they understand it.
+
+##### secure
+
+Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6266-5.2.5]. When truthy,
+the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
+the server in the future if the browser does not have an HTTPS connection.
+
+## Example
+
+The following example uses this module in conjunction with the Node.js core HTTP server
+to prompt a user for their name and display it back on future visits.
+
+```js
+var cookie = require('cookie');
+var escapeHtml = require('escape-html');
+var http = require('http');
+var url = require('url');
+
+function onRequest(req, res) {
+ // Parse the query string
+ var query = url.parse(req.url, true, true).query;
+
+ if (query && query.name) {
+ // Set a new cookie with the name
+ res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
+ httpOnly: true,
+ maxAge: 60 * 60 * 24 * 7 // 1 week
+ }));
+
+ // Redirect back after setting cookie
+ res.statusCode = 302;
+ res.setHeader('Location', req.headers.referer || '/');
+ res.end();
+ return;
+ }
+
+ // Parse the cookies on the request
+ var cookies = cookie.parse(req.headers.cookie || '');
+
+ // Get the visitor name set in the cookie
+ var name = cookies.name;
+
+ res.setHeader('Content-Type', 'text/html; charset=UTF-8');
+
+ if (name) {
+ res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
+ } else {
+ res.write('<p>Hello, new visitor!</p>');
+ }
+
+ res.write('<form method="GET">');
+ res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
+ res.end('</form');
+}
+
+http.createServer(onRequest).listen(3000);
+```

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(-3 * 60000) // "-3m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(-3 * 60000, { long: true }) // "-3 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+This module is not intended for end-user usage, but can be used as an
+interface to inherit from other adapters you might want to build.
+
+As an example of an adapter that builds on top of this, please take a look
+at [socket.io-redis](https://github.com/learnboost/socket.io-redis).

+
+## How to use
+
+A standalone build of `socket.io-client` is exposed automatically by the
+socket.io server as `/socket.io/socket.io.js`. Alternatively you can
+serve the file `socket.io.js` found in the `dist` folder or include it via [CDN](https://cdn.jsdelivr.net/npm/socket.io-client@2/dist/socket.io.js).
+
+```html
+<script src="/socket.io/socket.io.js"></script>
+<script>
+ var socket = io('http://localhost');
+ socket.on('connect', function(){});
+ socket.on('event', function(data){});
+ socket.on('disconnect', function(){});
+</script>
+```
+
+```js
+// with ES6 import
+import io from 'socket.io-client';
+
+const socket = io('http://localhost');
+```
+
+A slim build (without `JSON3`, a JSON polyfill for IE6/IE7, and `debug`) is also available: `socket.io.slim.js`.
+
+Socket.IO is compatible with [browserify](http://browserify.org/) and [webpack](https://webpack.js.org/) (see example [there](https://github.com/socketio/socket.io/tree/2.0.3/examples/webpack-build)).
+
+### Node.JS (server-side usage)
+
+ Add `socket.io-client` to your `package.json` and then:
+
+ ```js
+ var socket = require('socket.io-client')('http://localhost');
+ socket.on('connect', function(){});
+ socket.on('event', function(data){});
+ socket.on('disconnect', function(){});
+ ```

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://spectrum.chat/zeit)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+ms('-3 days') // -259200000
+ms('-1h') // -3600000
+ms('-200') // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(-3 * 60000) // "-3m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(-3 * 60000, { long: true }) // "-3 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# socket.io-parser
+
+[](http://travis-ci.org/socketio/socket.io-parser)
+[](http://badge.fury.io/js/socket.io-parser)
+
+A socket.io encoder and decoder written in JavaScript complying with version `3`
+of [socket.io-protocol](https://github.com/socketio/socket.io-protocol).
+Used by [socket.io](https://github.com/automattic/socket.io) and
+[socket.io-client](https://github.com/automattic/socket.io-client).
+
+## Parser API
+
+ socket.io-parser is the reference implementation of socket.io-protocol. Read
+ the full API here:
+ [socket.io-protocol](https://github.com/learnboost/socket.io-protocol).
+
+## Example Usage
+
+### Encoding and decoding a packet
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+ type: parser.EVENT,
+ data: 'test-packet',
+ id: 13
+};
+encoder.encode(packet, function(encodedPackets) {
+ var decoder = new parser.Decoder();
+ decoder.on('decoded', function(decodedPacket) {
+ // decodedPacket.type == parser.EVENT
+ // decodedPacket.data == 'test-packet'
+ // decodedPacket.id == 13
+ });
+
+ for (var i = 0; i < encodedPackets.length; i++) {
+ decoder.add(encodedPackets[i]);
+ }
+});
+```
+
+### Encoding and decoding a packet with binary data
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+ type: parser.BINARY_EVENT,
+ data: {i: new Buffer(1234), j: new Blob([new ArrayBuffer(2)])}
+ id: 15
+};
+encoder.encode(packet, function(encodedPackets) {
+ var decoder = new parser.Decoder();
+ decoder.on('decoded', function(decodedPacket) {
+ // decodedPacket.type == parser.BINARY_EVENT
+ // Buffer.isBuffer(decodedPacket.data.i) == true
+ // Buffer.isBuffer(decodedPacket.data.j) == true
+ // decodedPacket.id == 15
+ });
+
+ for (var i = 0; i < encodedPackets.length; i++) {
+ decoder.add(encodedPackets[i]);
+ }
+});
+```
+See the test suite for more examples of how socket.io-parser is used.

+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows note
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Note that PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Then, run the program to be debugged as usual.
+
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# socket.io-parser
+
+[](http://travis-ci.org/socketio/socket.io-parser)
+[](http://badge.fury.io/js/socket.io-parser)
+
+A socket.io encoder and decoder written in JavaScript complying with version `4`
+of [socket.io-protocol](https://github.com/socketio/socket.io-protocol).
+Used by [socket.io](https://github.com/automattic/socket.io) and
+[socket.io-client](https://github.com/automattic/socket.io-client).
+
+## Parser API
+
+ socket.io-parser is the reference implementation of socket.io-protocol. Read
+ the full API here:
+ [socket.io-protocol](https://github.com/learnboost/socket.io-protocol).
+
+## Example Usage
+
+### Encoding and decoding a packet
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+ type: parser.EVENT,
+ data: 'test-packet',
+ id: 13
+};
+encoder.encode(packet, function(encodedPackets) {
+ var decoder = new parser.Decoder();
+ decoder.on('decoded', function(decodedPacket) {
+ // decodedPacket.type == parser.EVENT
+ // decodedPacket.data == 'test-packet'
+ // decodedPacket.id == 13
+ });
+
+ for (var i = 0; i < encodedPackets.length; i++) {
+ decoder.add(encodedPackets[i]);
+ }
+});
+```
+
+### Encoding and decoding a packet with binary data
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+ type: parser.BINARY_EVENT,
+ data: {i: new Buffer(1234), j: new Blob([new ArrayBuffer(2)])}
+ id: 15
+};
+encoder.encode(packet, function(encodedPackets) {
+ var decoder = new parser.Decoder();
+ decoder.on('decoded', function(decodedPacket) {
+ // decodedPacket.type == parser.BINARY_EVENT
+ // Buffer.isBuffer(decodedPacket.data.i) == true
+ // Buffer.isBuffer(decodedPacket.data.j) == true
+ // decodedPacket.id == 15
+ });
+
+ for (var i = 0; i < encodedPackets.length; i++) {
+ decoder.add(encodedPackets[i]);
+ }
+});
+```
+See the test suite for more examples of how socket.io-parser is used.

+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://spectrum.chat/zeit)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+ms('-3 days') // -259200000
+ms('-1h') // -3600000
+ms('-200') // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(-3 * 60000) // "-3m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(-3 * 60000, { long: true }) // "-3 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+
+## Features
+
+Socket.IO enables real-time bidirectional event-based communication. It consists of:
+
+- a Node.js server (this repository)
+- a [Javascript client library](https://github.com/socketio/socket.io-client) for the browser (or a Node.js client)
+
+Some implementations in other languages are also available:
+
+- [Java](https://github.com/socketio/socket.io-client-java)
+- [C++](https://github.com/socketio/socket.io-client-cpp)
+- [Swift](https://github.com/socketio/socket.io-client-swift)
+- [Dart](https://github.com/rikulo/socket.io-client-dart)
+
+Its main features are:
+
+#### Reliability
+
+Connections are established even in the presence of:
+ - proxies and load balancers.
+ - personal firewall and antivirus software.
+
+For this purpose, it relies on [Engine.IO](https://github.com/socketio/engine.io), which first establishes a long-polling connection, then tries to upgrade to better transports that are "tested" on the side, like WebSocket. Please see the [Goals](https://github.com/socketio/engine.io#goals) section for more information.
+
+#### Auto-reconnection support
+
+Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options [here](https://github.com/socketio/socket.io-client/blob/master/docs/API.md#new-managerurl-options).
+
+#### Disconnection detection
+
+A heartbeat mechanism is implemented at the Engine.IO level, allowing both the server and the client to know when the other one is not responding anymore.
+
+That functionality is achieved with timers set on both the server and the client, with timeout values (the `pingInterval` and `pingTimeout` parameters) shared during the connection handshake. Those timers require any subsequent client calls to be directed to the same server, hence the `sticky-session` requirement when using multiples nodes.
+
+#### Binary support
+
+Any serializable data structures can be emitted, including:
+
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) in the browser
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Buffer](https://nodejs.org/api/buffer.html) in Node.js
+
+#### Simple and convenient API
+
+Sample code:
+
+```js
+io.on('connection', socket => {
+ socket.emit('request', /* … */); // emit an event to the socket
+ io.emit('broadcast', /* … */); // emit an event to all connected sockets
+ socket.on('reply', () => { /* … */ }); // listen to the event
+});
+```
+
+#### Cross-browser
+
+Browser support is tested in Saucelabs:
+
+[](https://saucelabs.com/u/socket)
+
+#### Multiplexing support
+
+In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create several `Namespaces`, which will act as separate communication channels but will share the same underlying connection.
+
+#### Room support
+
+Within each `Namespace`, you can define arbitrary channels, called `Rooms`, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it.
+
+This is a useful feature to send notifications to a group of users, or to a given user connected on several devices for example.
+
+
+**Note:** Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like `ws://echo.websocket.org`) either. Please see the protocol specification [here](https://github.com/socketio/socket.io-protocol).
+
+## Installation
+
+```bash
+npm install socket.io
+```
+
+## How to use
+
+The following example attaches socket.io to a plain Node.JS
+HTTP server listening on port `3000`.
+
+```js
+const server = require('http').createServer();
+const io = require('socket.io')(server);
+io.on('connection', client => {
+ client.on('event', data => { /* … */ });
+ client.on('disconnect', () => { /* … */ });
+});
+server.listen(3000);
+```
+
+### Standalone
+
+```js
+const io = require('socket.io')();
+io.on('connection', client => { ... });
+io.listen(3000);
+```
+
+### In conjunction with Express
+
+Starting with **3.0**, express applications have become request handler
+functions that you pass to `http` or `http` `Server` instances. You need
+to pass the `Server` to `socket.io`, and not the express application
+function. Also make sure to call `.listen` on the `server`, not the `app`.
+
+```js
+const app = require('express')();
+const server = require('http').createServer(app);
+const io = require('socket.io')(server);
+io.on('connection', () => { /* … */ });
+server.listen(3000);
+```
+
+### In conjunction with Koa
+
+Like Express.JS, Koa works by exposing an application as a request
+handler function, but only by calling the `callback` method.
+
+```js
+const app = require('koa')();
+const server = require('http').createServer(app.callback());
+const io = require('socket.io')(server);
+io.on('connection', () => { /* … */ });
+server.listen(3000);
+```
+
+## Documentation
+
+Please see the documentation [here](/docs/README.md). Contributions are welcome!
+
+## Debug / logging
+
+Socket.IO is powered by [debug](https://github.com/visionmedia/debug).
+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Socket.IO's debugging scopes you can use:
+
+```
+DEBUG=socket.io* node myapp
+```
+
+## Testing
+
+```
+npm test
+```
+This runs the `gulp` task `test`. By default the test will be run with the source code in `lib` directory.
+
+Set the environmental variable `TEST_VERSION` to `compat` to test the transpiled es5-compat version of the code.
+
+The `gulp` task `test` will always transpile the source code into es5 and export to `dist` first before running the test.

+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://spectrum.chat/zeit)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+ms('-3 days') // -259200000
+ms('-1h') // -3600000
+ms('-200') // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(-3 * 60000) // "-3m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(-3 * 60000, { long: true }) // "-3 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# ws: a Node.js WebSocket library
+
+[](https://www.npmjs.com/package/ws)
+[](https://travis-ci.com/websockets/ws)
+[](https://ci.appveyor.com/project/lpinca/ws)
+[](https://coveralls.io/github/websockets/ws)
+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
+server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
+object. To make the same code work seamlessly on Node.js and the browser, you
+can use one of the many wrappers available on npm, like
+[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

+## Protocol support
+
+- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+- **HyBi drafts 13-17** (Current default, alternatively option
+ `protocolVersion: 13`)
+
+## Installing
+
+```
+npm install ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+ operations such as masking and unmasking the data payload of the WebSocket
+ frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
+ message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and
+utility functions.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which enables
+the client and server to negotiate a compression algorithm and its parameters,
+and then selectively apply it to the data payloads of each WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on the
+client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+Note that Node.js has a variety of issues with high-performance compression,
+where increased concurrency, especially on Linux, can lead to [catastrophic
+memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
+permessage-deflate in production, it is worthwhile to set up a test
+representative of your workload and ensure Node.js/zlib will handle it with
+acceptable performance and memory usage.
+
+Tuning of permessage-deflate can be done via the options defined below. You can
+also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
+into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
+
+See [the docs][ws-server-options] for more options.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({
+ port: 8080,
+ perMessageDeflate: {
+ zlibDeflateOptions: {
+ // See zlib defaults.
+ chunkSize: 1024,
+ memLevel: 7,
+ level: 3
+ },
+ zlibInflateOptions: {
+ chunkSize: 10 * 1024
+ },
+ // Other options settable:
+ clientNoContextTakeover: true, // Defaults to negotiated value.
+ serverNoContextTakeover: true, // Defaults to negotiated value.
+ serverMaxWindowBits: 10, // Defaults to negotiated value.
+ // Below options specified as default values.
+ concurrencyLimit: 10, // Limits zlib concurrency for perf.
+ threshold: 1024 // Size (in bytes) below which messages
+ // should not be compressed.
+ }
+});
+```
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+ perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+ console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ const array = new Float32Array(5);
+
+ for (var i = 0; i < array.length; ++i) {
+ array[i] = i / 2;
+ }
+
+ ws.send(array);
+});
+```
+
+### Simple server
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+```
+
+### External HTTP/S server
+
+```js
+const fs = require('fs');
+const https = require('https');
+const WebSocket = require('ws');
+
+const server = https.createServer({
+ cert: fs.readFileSync('/path/to/cert.pem'),
+ key: fs.readFileSync('/path/to/key.pem')
+});
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+
+server.listen(8080);
+```
+
+### Multiple servers sharing a single HTTP/S server
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+const url = require('url');
+
+const server = http.createServer();
+const wss1 = new WebSocket.Server({ noServer: true });
+const wss2 = new WebSocket.Server({ noServer: true });
+
+wss1.on('connection', function connection(ws) {
+ // ...
+});
+
+wss2.on('connection', function connection(ws) {
+ // ...
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+ const pathname = url.parse(request.url).pathname;
+
+ if (pathname === '/foo') {
+ wss1.handleUpgrade(request, socket, head, function done(ws) {
+ wss1.emit('connection', ws, request);
+ });
+ } else if (pathname === '/bar') {
+ wss2.handleUpgrade(request, socket, head, function done(ws) {
+ wss2.emit('connection', ws, request);
+ });
+ } else {
+ socket.destroy();
+ }
+});
+
+server.listen(8080);
+```
+
+### Client authentication
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+
+const server = http.createServer();
+const wss = new WebSocket.Server({ noServer: true });
+
+wss.on('connection', function connection(ws, request, client) {
+ ws.on('message', function message(msg) {
+ console.log(`Received message ${msg} from user ${client}`);
+ });
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+ authenticate(request, (err, client) => {
+ if (err || !client) {
+ socket.destroy();
+ return;
+ }
+
+ wss.handleUpgrade(request, socket, head, function done(ws) {
+ wss.emit('connection', ws, request, client);
+ });
+ });
+});
+
+server.listen(8080);
+```
+
+Also see the provided [example][session-parse-example] using `express-session`.
+
+### Server broadcast
+
+A client WebSocket broadcasting to all connected WebSocket clients, including
+itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(data) {
+ wss.clients.forEach(function each(client) {
+ if (client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+ });
+});
+```
+
+A client WebSocket broadcasting to every other connected WebSocket clients,
+excluding itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(data) {
+ wss.clients.forEach(function each(client) {
+ if (client !== ws && client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+ });
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+ origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+ console.log('connected');
+ ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+ console.log('disconnected');
+});
+
+ws.on('message', function incoming(data) {
+ console.log(`Roundtrip time: ${Date.now() - data} ms`);
+
+ setTimeout(function timeout() {
+ ws.send(Date.now());
+ }, 500);
+});
+```
+
+### Use the Node.js streams API
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+ origin: 'https://websocket.org'
+});
+
+const duplex = WebSocket.createWebSocketStream(ws, { encoding: 'utf8' });
+
+duplex.pipe(process.stdout);
+process.stdin.pipe(duplex);
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+ const ip = req.connection.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+ const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a way
+that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+function noop() {}
+
+function heartbeat() {
+ this.isAlive = true;
+}
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.isAlive = true;
+ ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+ wss.clients.forEach(function each(ws) {
+ if (ws.isAlive === false) return ws.terminate();
+
+ ws.isAlive = false;
+ ws.ping(noop);
+ });
+}, 30000);
+
+wss.on('close', function close() {
+ clearInterval(interval);
+});
+```
+
+Pong messages are automatically sent in response to ping messages as required by
+the spec.
+
+Just like the server example above your clients might as well lose connection
+without knowing it. You might want to add a ping listener on your clients to
+prevent that. A simple implementation would be:
+
+```js
+const WebSocket = require('ws');
+
+function heartbeat() {
+ clearTimeout(this.pingTimeout);
+
+ // Use `WebSocket#terminate()`, which immediately destroys the connection,
+ // instead of `WebSocket#close()`, which waits for the close timer.
+ // Delay should be equal to the interval at which your server
+ // sends out pings plus a conservative assumption of the latency.
+ this.pingTimeout = setTimeout(() => {
+ this.terminate();
+ }, 30000 + 1000);
+}
+
+const client = new WebSocket('wss://echo.websocket.org/');
+
+client.on('open', heartbeat);
+client.on('ping', heartbeat);
+client.on('close', function clear() {
+ clearTimeout(this.pingTimeout);
+});
+```
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].

+# node-XMLHttpRequest #
+
+Fork of [node-XMLHttpRequest](https://github.com/driverdan/node-XMLHttpRequest) by [driverdan](http://driverdan.com). Forked and published to npm because a [pull request](https://github.com/rase-/node-XMLHttpRequest/commit/a6b6f296e0a8278165c2d0270d9840b54d5eeadd) is not being created and merged. Changes made by [rase-](https://github.com/rase-/node-XMLHttpRequest/tree/add/ssl-support) are needed for [engine.io-client](https://github.com/Automattic/engine.io-client).
+
+## Usage ##
+
+Here's how to include the module in your project and use as the browser-based
+XHR object.
+
+ var XMLHttpRequest = require("xmlhttprequest-ssl").XMLHttpRequest;
+ var xhr = new XMLHttpRequest();
+
+Note: use the lowercase string "xmlhttprequest-ssl" in your require(). On
+case-sensitive systems (eg Linux) using uppercase letters won't work.

+## Usage ##
+
+Here's how to include the module in your project and use as the browser-based

+
+ var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
+ var xhr = new XMLHttpRequest();
+
+Note: use the lowercase string "xmlhttprequest" in your require(). On
+case-sensitive systems (eg Linux) using uppercase letters won't work.
+
+## Versions ##
+
+Prior to 1.4.0 version numbers were arbitrary. From 1.4.0 on they conform to
+the standard major.minor.bugfix. 1.x shouldn't necessarily be considered
+stable just because it's above 0.x.
+
+Since the XMLHttpRequest API is stable this library's API is stable as
+well. Major version numbers indicate significant core code changes.
+Minor versions indicate minor core code changes or better conformity to
+the W3C spec.
+
+## License ##
+
+MIT license. See LICENSE for full details.
+
+## Supports ##
+
+* Async and synchronous requests
+* GET, POST, PUT, and DELETE requests
+* All spec methods (open, send, abort, getRequestHeader,
+ getAllRequestHeaders, event methods)
+* Requests to all domains
+
+## Known Issues / Missing Features ##
+
+For a list of open issues or to report your own visit the [github issues
+page](https://github.com/driverdan/node-XMLHttpRequest/issues).
+
+* Local file access may have unexpected results for non-UTF8 files
+* Synchronous requests don't set headers properly
+* Synchronous requests freeze node while waiting for response (But that's what you want, right? Stick with async!).
+* Some events are missing, such as abort
+* getRequestHeader is case-sensitive
+* Cookies aren't persisted between requests
+* Missing XML support
+* Missing basic auth

+[](https://saucelabs.com/u/yeast)
+
+Yeast is a unique id generator. It has been primarily designed to generate a
+unique id which can be used for cache busting. A common practice for this is
+to use a timestamp, but there are couple of downsides when using timestamps.
+
+1. The timestamp is already 13 chars long. This might not matter for 1 request
+ but if you make hundreds of them this quickly adds up in bandwidth and
+ processing time.
+2. It's not unique enough. If you generate two stamps right after each other,
+ they would be identical because the timing accuracy is limited to
+ milliseconds.
+
+Yeast solves both of these issues by:
+
+1. Compressing the generated timestamp using a custom `encode()` function that
+ returns a string representation of the number.
+2. Seeding the id in case of collision (when the id is identical to the previous
+ one).
+
+To keep the strings unique it will use the `.` char to separate the generated
+stamp from the seed.
+
+## Installation
+
+The module is intended to be used in browsers as well as in Node.js and is
+therefore released in the npm registry and can be installed using:
+
+```
+npm install --save yeast
+```
+
+## Usage
+
+All the examples assume that this library is initialized as follow:
+
+```js
+'use strict';
+
+var yeast = require('yeast');
+```
+
+To generate an id just call the `yeast` function.
+
+```js
+console.log(yeast(), yeast(), yeast()); // outputs: KyxidwN KyxidwN.0 KyxidwN.1
+
+setTimeout(function () {
+ console.log(yeast()); // outputs: KyxidwO
+});
+```
+
+### yeast.encode(num)
+
+An helper function that returns a string representing the specified number. The
+returned string contains only URL safe characters.
+
+```js
+yeast.encode(+new Date()); // outputs: Kyxjuo1
+```
+
+### yeast.decode(str)
+
+An helper function that returns the integer value specified by the given string.
+This function can be used to retrieve the timestamp from a `yeast` id.
+
+```js
+var id = yeast(); // holds the value: Kyxl1OU
+
+yeast.decode(id); // outputs: 1439816226334
+```
+
+That's all folks. If you have ideas on how we can further compress the ids
+please open an issue!
