+# Engine.IO client
+
+[![Build Status](https://travis-ci.org/socketio/engine.io-client.svg?branch=master)](http://travis-ci.org/socketio/engine.io-client)
+[![NPM version](https://badge.fury.io/js/engine.io-client.svg)](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

+# Emitter [![Build Status](https://travis-ci.org/component/emitter.png)](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.

+
+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.
+
+<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.

+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Join the community on Spectrum](https://withspectrum.github.io/badge/badge.svg)](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
+
+[![Version npm](https://img.shields.io/npm/v/ws.svg)](https://www.npmjs.com/package/ws)
+[![Linux Build](https://img.shields.io/travis/websockets/ws/master.svg)](https://travis-ci.org/websockets/ws)
+[![Windows Build](https://ci.appveyor.com/api/projects/status/github/websockets/ws?branch=master&svg=true)](https://ci.appveyor.com/project/lpinca/ws)
+[![Coverage Status](https://img.shields.io/coveralls/websockets/ws/master.svg)](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][].
