-# Your Project Name
+# QUIKDRAW
-This is the starter code for WDI projects. Please update this README file with information specific to your project. Replace this paragraph for instance, with a short description of your project. Then update the sections below. Refer to your project specificaion for instructions on how to submit your projects.
-## Getting Started
-Provide instructions here about how to get your project running on our local machine. Do we just need to clone and open a certain file or do we need to install anything first.
+## About
-### Prerequisites
+Quikdraw is an easy-to-play game where you would take turns with your matched partner to guess what the other is drawing. The more answers you get right, the more points you get!
-What is needed to install and run the project, how do we install them
+### Socket.io
-```
-Code example
-```
-
-### How to Use
-
-A step by step guide on how to install and use the project, for example if this is a game, how do we play it.

-## Tests
-
-Did you write automated tests? If so, how do we run them.
+Socket.io was used in this project to allow a multiplayer interface on QUIKDRAW. Socket.io was crucial in allowing me to enable a simultaneous connection between the client and server.
```
-Code example
+var rooms = []
+var roomNum = 1
+
+io.on('connection', function(socket){
+ // console.log(socket.id, "user connected")
+ // socket.on('adduser', function (username) {
+ users.push(socket.id)
+ // console.log(rooms.length)
+
+ if(rooms.length === 0 ) {
+ rooms.push(socket.id)
+ socket.room = "room" + roomNum
+ socket.turn = true
+ console.log(socket.id + " " + socket.turn)
+ socket.join("room" + roomNum)
+ io.of('/').adapter.clients([socket.room], (err, clients) => {
+
+ } else if (rooms.length % 2 === 1) {
+ rooms.push(socket.id)
+
+ socket.room = "room" + roomNum
+ socket.join("room" + roomNum)
+
+ io.of('/').adapter.clients([socket.room], (err, clients) => {
+ console.log(clients.length)
+ if (clients.length === 2) {
+ socket.turn = false
+ console.log(socket.id + " " + socket.turn + "line 57")
+ } else if(clients.length === 1) {
+ socket.turn = true
+ console.log(socket.id + " " + socket.turn + " line 61")
+ rooms.pop()
+
+ }
+
+ })
+ } else if (rooms.length % 2 === 0) {
+ socket.turn = true
+
+ roomNum ++
+ socket.room = "room" + roomNum
+ rooms.push(socket.id)
+ socket.join("room" + roomNum)
+ io.of('/').adapter.clients([socket.room], (err, clients) => {
+ })
+ }
```
-## Live Version
-
-Where is this deployed online (github pages, heroku etc), give us the link and any access details we need.
+Each player who establishes a connection with the server would have his unique socket ID pushed into the rooms array. Each odd player would be the person who draws first while each even player would be the matching partner who would get to guess.
-## Built With
+If a person establishes a connection and realizes that he is an even player but at the same time in a room with only one person, I would then ensure that his turn is turned back to true while at the same time reducing the length of the rooms arrayby one to return the room matching algorithm back to normal.
-What did you use to build it, list the technologies, plugins, gems, packages etc.
+Furthermore, when the browser is refreshed, a player loses connection and would then have to connect to the server again losing his current game.
-* [jQuery](http://jquery.com/) - jQuery for example is something you likely used
-## Workflow
+## Canvas
-Did you write user stories, draw wireframes, use task tracking, produce ERDs? Did you use source control, with regular commits? Include links to them here.
+Canvas was key behind the whiteboard in QUIKDRAW.
-## Authors
+The function which draws lines on the canvas was Drawline.
-Did you collaborate with others on this project, list them here
+A key to take note was when emitting, we divide the coordinates by the local player's whiteboard width and height so that the remote player would receive the coordinates per unit of height and width. Before drawing on the whiteboard, the remote player would then have to mulitply the per unit coordinates by their own whiteboard's width and height. This ensures that varying screen size does not matter when drawing on the whiteboard.

+```
+function drawLine(x0, y0, x1, y1, color, emit){
+ context.beginPath();
+ context.moveTo(x0, y0);
+ context.lineTo(x1, y1);
+ context.strokeStyle = color;
+ if (color === "white") {
+ context.lineWidth = 20
+ } else{
+ context.lineWidth = 2;
+ }
+ context.stroke();
+ context.closePath();
+
+ if (!emit) { return; }
+ var w = canvas.width;
+ var h = canvas.height;
+
+ socket.emit('drawing', {
+ x0: x0 / w,
+ y0: y0 / h,
+ x1: x1 / w,
+ y1: y1 / h,
+ color: color
+ });
+}
+```
-* Hat tip to anyone who's code was used, for example [this was a useful starting point for creating this template](https://gist.github.com/PurpleBooth/109311bb0361f32d87a2).

Instructions:
+
+ Click on PLAY NOW!
+ Wait to be matched with a partner, waiting time depends on the volume of players in the game
+ Upon being matched with a partner, game would begin immediately
+ Take turns to guess what your partner is drawing
+ Each correctly guessed answer will grant a point to the both of you
+ Draw and think fast though, both of you only have a minute till the game ends!

+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+ as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+ var accept = accepts(req)
+
+ // the order of this list is significant; should be server preferred order
+ switch (accept.type(['json', 'html'])) {
+ case 'json':
+ res.setHeader('Content-Type', 'application/json')
+ res.write('{"hello":"world!"}')
+ break
+ case 'html':
+ res.setHeader('Content-Type', 'text/html')
+ res.write('hello, world! ')
+ break
+ default:
+ // the fallback is text/plain, so no need to specify it above
+ res.setHeader('Content-Type', 'text/plain')
+ res.write('hello, world!')
+ break
+ }
+
+ res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+# 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)
+}
+```

+# ansi-regex [](https://travis-ci.org/chalk/ansi-regex)
+
+> Regular expression for matching [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code)
+
+
+## Install
+
+```
+$ npm install ansi-regex
+```
+
+
+## Usage
+
+```js
+const ansiRegex = require('ansi-regex');
+
+ansiRegex().test('\u001B[4mcake\u001B[0m');
+//=> true
+
+ansiRegex().test('cake');
+//=> false
+
+'\u001B[4mcake\u001B[0m'.match(ansiRegex());
+//=> ['\u001B[4m', '\u001B[0m']
+```
+
+
+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+# ansi-styles [](https://travis-ci.org/chalk/ansi-styles)
+
+> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+
+
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+// may be degraded to fit that color palette. This means terminals
+// that do not support 16 million colors will best-match the
+// original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray` ("bright black")
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright`
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+anymatch [](https://travis-ci.org/es128/anymatch) [](https://coveralls.io/r/es128/anymatch?branch=master)
+======
+Javascript module to match a string against a regular expression, glob, string,
+or function that takes the string as an argument and returns a truthy or falsy
+value. The matcher can also be an array of any or all of these. Useful for
+allowing a very flexible user-defined config to define things like file paths.
+
+[](https://nodei.co/npm/anymatch/)
+[](https://nodei.co/npm-dl/anymatch/)
+
+Usage
+-----
+```sh
+npm install anymatch --save
+```
+
+#### anymatch (matchers, testString, [returnIndex], [startIndex], [endIndex])
+* __matchers__: (_Array|String|RegExp|Function_)
+String to be directly matched, string with glob patterns, regular expression
+test, function that takes the testString as an argument and returns a truthy
+value if it should be matched, or an array of any number and mix of these types.
+* __testString__: (_String|Array_) The string to test against the matchers. If
+passed as an array, the first element of the array will be used as the
+`testString` for non-function matchers, while the entire array will be applied
+as the arguments for function matchers.
+* __returnIndex__: (_Boolean [optional]_) If true, return the array index of
+the first matcher that that testString matched, or -1 if no match, instead of a
+boolean result.
+* __startIndex, endIndex__: (_Integer [optional]_) Can be used to define a
+subset out of the array of provided matchers to test against. Can be useful
+with bound matcher functions (see below). When used with `returnIndex = true`
+preserves original indexing. Behaves the same as `Array.prototype.slice` (i.e.
+includes array members up to, but not including endIndex).
+
+```js
+var anymatch = require('anymatch');
+
+var matchers = [
+ 'path/to/file.js',
+ 'path/anyjs/**/*.js',
+ /foo\.js$/,
+ function (string) {
+ return string.indexOf('bar') !== -1 && string.length > 10
+ }
+];
+
+anymatch(matchers, 'path/to/file.js'); // true
+anymatch(matchers, 'path/anyjs/baz.js'); // true
+anymatch(matchers, 'path/to/foo.js'); // true
+anymatch(matchers, 'path/to/bar.js'); // true
+anymatch(matchers, 'bar.js'); // false
+
+// returnIndex = true
+anymatch(matchers, 'foo.js', true); // 2
+anymatch(matchers, 'path/anyjs/foo.js', true); // 1
+
+// skip matchers
+anymatch(matchers, 'path/to/file.js', false, 1); // false
+anymatch(matchers, 'path/anyjs/foo.js', true, 2, 3); // 2
+anymatch(matchers, 'path/to/bar.js', true, 0, 3); // -1
+
+// using globs to match directories and their children
+anymatch('node_modules', 'node_modules'); // true
+anymatch('node_modules', 'node_modules/somelib/index.js'); // false
+anymatch('node_modules/**', 'node_modules/somelib/index.js'); // true
+anymatch('node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // false
+anymatch('**/node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // true
+```
+
+#### anymatch (matchers)
+You can also pass in only your matcher(s) to get a curried function that has
+already been bound to the provided matching criteria. This can be used as an
+`Array.prototype.filter` callback.
+
+```js
+var matcher = anymatch(matchers);
+
+matcher('path/to/file.js'); // true
+matcher('path/anyjs/baz.js', true); // 1
+matcher('path/anyjs/baz.js', true, 2); // -1
+
+['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
+```
+
+Change Log
+----------
+[See release notes page on GitHub](https://github.com/es128/anymatch/releases)
+
+NOTE: As of v1.2.0, anymatch uses [micromatch](https://github.com/jonschlinkert/micromatch)
+for glob pattern matching. The glob matching behavior should be functionally
+equivalent to the commonly used [minimatch](https://github.com/isaacs/minimatch)
+library (aside from some fixed bugs and greater performance), so a major
+version bump wasn't merited. Issues with glob pattern matching should be
+reported directly to the [micromatch issue tracker](https://github.com/jonschlinkert/micromatch/issues).

+> Recursively flatten an array or arrays.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save arr-flatten
+```
+
+## Install
+
+Install with [bower](https://bower.io/)
+
+```sh
+$ bower install arr-flatten --save
+```
+
+## Usage
+
+```js
+var flatten = require('arr-flatten');
+
+flatten(['a', ['b', ['c']], 'd', ['e']]);
+//=> ['a', 'b', 'c', 'd', 'e']
+```
+
+## Why another flatten utility?
+
+I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.

+# array-unique [](http://badge.fury.io/js/array-unique) [](https://travis-ci.org/jonschlinkert/array-unique)
+
+> Return an array free of duplicate values. Fastest ES5 implementation.
+
+## Install with [npm](npmjs.org)
+
+```bash
+npm i array-unique --save
+```
+
+## Usage
+
+```js
+var unique = require('array-unique');
+
+unique(['a', 'b', 'c', 'c']);
+//=> ['a', 'b', 'c']
+```
+
+## Related
+* [arr-diff](https://github.com/jonschlinkert/arr-diff): Returns an array with only the unique values from the first array, by excluding all values from additional arrays using strict equality for comparisons.
+* [arr-union](https://github.com/jonschlinkert/arr-union): Returns an array of unique values using strict equality for comparisons.
+* [arr-flatten](https://github.com/jonschlinkert/arr-flatten): Recursively flatten an array or arrays. This is the fastest implementation of array flatten.
+* [arr-reduce](https://github.com/jonschlinkert/arr-reduce): Fast array reduce that also loops over sparse elements.
+* [arr-map](https://github.com/jonschlinkert/arr-map): Faster, node.js focused alternative to JavaScript's native array map.
+* [arr-pluck](https://github.com/jonschlinkert/arr-pluck): Retrieves the value of a specified property from all elements in the collection.
+
+## Run tests
+Install dev dependencies.
+
+```bash
+npm i -d && npm test
+```

+# async-each
+
+No-bullshit, ultra-simple, 35-lines-of-code async parallel forEach function for JavaScript.
+
+We don't need junky 30K async libs. Really.
+
+For browsers and node.js.
+
+## Installation
+* Just include async-each before your scripts.
+* `npm install async-each` if you’re using node.js.
+* `bower install async-each` if you’re using [Bower](http://bower.io).
+
+## Usage
+
+* `each(array, iterator, callback);` — `Array`, `Function`, `(optional) Function`
+* `iterator(item, next)` receives current item and a callback that will mark the item as done. `next` callback receives optional `error, transformedItem` arguments.
+* `callback(error, transformedArray)` optionally receives first error and transformed result `Array`.
+
+Node.js:
+
+```javascript
+var each = require('async-each');
+each(['a.js', 'b.js', 'c.js'], fs.readFile, function(error, contents) {
+ if (error) console.error(error);
+ console.log('Contents for a, b and c:', contents);
+});
+```
+
+Browser:
+
+```javascript
+window.asyncEach(list, fn, callback);
+```

+
+### 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
+
+ ```
+
+### Sending and receiving binary
+
+```html
+
+
+```
+
+### 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.
+ - `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.
+ - `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`): 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`)
+ - `requestTimeout` (`Number`): Timeout for xhr-polling requests in milliseconds (`0`)
+ - `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
+- `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:
+
+```bash
+git clone git://github.com/socketio/engine.io-client.git
+```
+
+Then:
+
+```bash
+cd engine.io-client
+npm install
+```
+
+See the `Tests` section above for how to run tests before submitting any patches.

+
+## API
+
+### `ansiAlign(text, [opts])`
+
+Align the given text per the line with the greatest [`string-width`](https://github.com/sindresorhus/string-width), returning a new string (or array).
+
+#### Arguments
+
+- `text`: required, string or array
+
+ The text to align. If a string is given, it will be split using either the `opts.split` value or `'\n'` by default. If an array is given, a different array of modified strings will be returned.
+
+- `opts`: optional, object
+
+ Options to change behavior, see below.
+
+#### Options
+
+- `opts.align`: string, default `'center'`
+
+ The alignment mode. Use `'center'` for center-alignment, `'right'` for right-alignment, or `'left'` for left-alignment. Note that the given `text` is assumed to be left-aligned already, so specifying `align: 'left'` just returns the `text` as is (no-op).
+
+- `opts.split`: string or RegExp, default `'\n'`
+
+ The separator to use when splitting the text. Only used if text is given as a string.
+
+- `opts.pad`: string, default `' '`
+
+ The value used to left-pad (prepend to) lines of lesser width. Will be repeated as necessary to adjust alignment to the line with the greatest width.
+
+### `ansiAlign.center(text)`
+
+Alias for `ansiAlign(text, { align: 'center' })`.
+
+### `ansiAlign.right(text)`
+
+Alias for `ansiAlign(text, { align: 'right' })`.
+
+### `ansiAlign.left(text)`
+
+Alias for `ansiAlign(text, { align: 'left' })`, which is a no-op.
+
+## Similar Packages
+
+- [`center-align`](https://github.com/jonschlinkert/center-align): Very close to this package, except it doesn't support ANSI codes.
+- [`left-pad`](https://github.com/camwest/left-pad): Great for left-padding but does not support center alignment or ANSI codes.
+- Pretty much anything by the [chalk](https://github.com/chalk) team
