[![Downloads/month](https://img.shields.io/npm/dm/abort-controller.svg)](http://www.npmtrends.com/abort-controller)
[![Build Status](https://travis-ci.org/mysticatea/abort-controller.svg?branch=master)](https://travis-ci.org/mysticatea/abort-controller)
[![Coverage Status](https://codecov.io/gh/mysticatea/abort-controller/branch/master/graph/badge.svg)](https://codecov.io/gh/mysticatea/abort-controller)
[![Dependency Status](https://david-dm.org/mysticatea/abort-controller.svg)](https://david-dm.org/mysticatea/abort-controller)
An implementation of [WHATWG AbortController interface](https://dom.spec.whatwg.org/#interface-abortcontroller).
```js
import AbortController from "abort-controller"
const controller = new AbortController()
const signal = controller.signal
signal.addEventListener("abort", () => {
console.log("aborted!")
})
controller.abort()
```
> https://jsfiddle.net/1r2994qp/1/
## 💿 Installation
Use [npm](https://www.npmjs.com/) to install then use a bundler.
```
npm install abort-controller
```
Or download from [`dist` directory](./dist).
- [dist/abort-controller.mjs](dist/abort-controller.mjs) ... ES modules version.
- [dist/abort-controller.js](dist/abort-controller.js) ... Common JS version.
- [dist/abort-controller.umd.js](dist/abort-controller.umd.js) ... UMD (Universal Module Definition) version. This is transpiled by [Babel](https://babeljs.io/) for IE 11.
## 📖 Usage
### Basic
```js
import AbortController from "abort-controller"
// or
const AbortController = require("abort-controller")
// or UMD version defines a global variable:
const AbortController = window.AbortControllerShim
```
If your bundler recognizes `browser` field of `package.json`, the imported `AbortController` is the native one and it doesn't contain shim (even if the native implementation was nothing).
If you wanted to polyfill `AbortController` for IE, use `abort-controller/polyfill`.
### Polyfilling
Importing `abort-controller/polyfill` assigns the `AbortController` shim to the `AbortController` global variable if the native implementation was nothing.
```js
import "abort-controller/polyfill"
// or
require("abort-controller/polyfill")
```
### API
#### AbortController
> https://dom.spec.whatwg.org/#interface-abortcontroller
##### controller.signal
The [AbortSignal](https://dom.spec.whatwg.org/#interface-AbortSignal) object which is associated to this controller.
##### controller.abort()
Notify `abort` event to listeners that the `signal` has.

### Turn a function into an [`http.Agent`][http.Agent] instance
[![Build Status](https://travis-ci.org/TooTallNate/node-agent-base.svg?branch=master)](https://travis-ci.org/TooTallNate/node-agent-base)
This module provides an `http.Agent` generator. That is, you pass it an async
callback function, and it returns a new `http.Agent` instance that will invoke the
given callback function when sending outbound HTTP requests.
#### Some subclasses:
Here's some more interesting uses of `agent-base`.
Send a pull request to list yours!
* [`http-proxy-agent`][http-proxy-agent]: An HTTP(s) proxy `http.Agent` implementation for HTTP endpoints
* [`https-proxy-agent`][https-proxy-agent]: An HTTP(s) proxy `http.Agent` implementation for HTTPS endpoints
* [`pac-proxy-agent`][pac-proxy-agent]: A PAC file proxy `http.Agent` implementation for HTTP and HTTPS
* [`socks-proxy-agent`][socks-proxy-agent]: A SOCKS (v4a) proxy `http.Agent` implementation for HTTP and HTTPS
Installation
------------
Install with `npm`:
``` bash
$ npm install agent-base
```
Example
-------
Here's a minimal example that creates a new `net.Socket` connection to the server
for every HTTP request (i.e. the equivalent of `agent: false` option):
```js
var net = require('net');
var tls = require('tls');
var url = require('url');
var http = require('http');
var agent = require('agent-base');
var endpoint = 'http://nodejs.org/api/';
var parsed = url.parse(endpoint);
// This is the important part!
parsed.agent = agent(function (req, opts) {
var socket;
// `secureEndpoint` is true when using the https module
if (opts.secureEndpoint) {
socket = tls.connect(opts);
} else {
socket = net.connect(opts);
}
return socket;
});
// Everything else works just like normal...
http.get(parsed, function (res) {
console.log('"response" event!', res.headers);
res.pipe(process.stdout);
});
```
Returning a Promise or using an `async` function is also supported:
```js
agent(async function (req, opts) {
await sleep(1000);
// etc…
});
```
Return another `http.Agent` instance to "pass through" the responsibility
for that HTTP request to that agent:
```js
agent(function (req, opts) {
return opts.secureEndpoint ? https.globalAgent : http.globalAgent;
});
```
API
---
## Agent(Function callback[, Object options]) → [http.Agent][]
Creates a base `http.Agent` that will execute the callback function `callback`
for every HTTP request that it is used as the `agent` for. The callback function
is responsible for creating a `stream.Duplex` instance of some kind that will be
used as the underlying socket in the HTTP request.
The `options` object accepts the following properties:
* `timeout` - Number - Timeout for the `callback()` function in milliseconds. Defaults to Infinity (optional).
The callback function should have the following signature:
### callback(http.ClientRequest req, Object options, Function cb) → undefined
The ClientRequest `req` can be accessed to read request headers and
and the path, etc. The `options` object contains the options passed
to the `http.request()`/`https.request()` function call, and is formatted
to be directly passed to `net.connect()`/`tls.connect()`, or however
else you want a Socket to be created. Pass the created socket to
the callback function `cb` once created, and the HTTP request will
continue to proceed.
If the `https` module is used to invoke the HTTP request, then the
`secureEndpoint` property on `options` _will be set to `true`_.

base64-js
=========
`base64-js` does basic base64 encoding/decoding in pure JS.
[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](http://travis-ci.org/beatgammit/base64-js)
Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
## install
With [npm](https://npmjs.org) do:
`npm install base64-js` and `var base64js = require('base64-js')`
For use in web browsers do:
`<script src="base64js.min.js"></script>`
## methods
`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
* `byteLength` - Takes a base64 string and returns length of byte array
* `toByteArray` - Takes a base64 string and returns a byte array

![bignumber.js](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/bignumberjs.png)
A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic.
[![Build Status](https://travis-ci.org/MikeMcl/bignumber.js.svg)](https://travis-ci.org/MikeMcl/bignumber.js)
<br />
## Features
- Integers and decimals
- Simple API but full-featured
- Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
- 8 KB minified and gzipped
- Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
- Includes a `toFraction` and a correctly-rounded `squareRoot` method
- Supports cryptographically-secure pseudo-random number generation
- No dependencies
- Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
- Comprehensive [documentation](http://mikemcl.github.io/bignumber.js/) and test set
![API](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/API.png)
If a smaller and simpler library is required see [big.js](https://github.com/MikeMcl/big.js/).
It's less than half the size but only works with decimal numbers and only has half the methods.
It also does not allow `NaN` or `Infinity`, or have the configuration options of this library.
See also [decimal.js](https://github.com/MikeMcl/decimal.js/), which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.
## Load
The library is the single JavaScript file *bignumber.js* (or minified, *bignumber.min.js*).
Browser:
```html
<script src='path/to/bignumber.js'></script>
```
[Node.js](http://nodejs.org):
```bash
$ npm install --save bignumber.js
```
```javascript
var BigNumber = require('bignumber.js');
```
ES6 module (*bignumber.mjs*):
```javascript
//import BigNumber from 'bignumber.js';
import {BigNumber} from 'bignumber.js';
```
AMD loader libraries such as [requireJS](http://requirejs.org/):
```javascript
require(['bignumber'], function(BigNumber) {
// Use BigNumber here in local scope. No global BigNumber.
});
```
## Use
*In all examples below, `var`, semicolons and `toString` calls are not shown.
If a commented-out value is in quotes it means `toString` has been called on the preceding expression.*
The library exports a single function: `BigNumber`, the constructor of BigNumber instances.
It accepts a value of type Number, String or BigNumber,
```javascript
x = new BigNumber(123.4567)
y = BigNumber('123456.7e-3')
z = new BigNumber(x)
x.isEqualTo(y) && y.isEqualTo(z) && x.isEqualTo(z) // true
```
and a base can be specified.
```javascript
a = new BigNumber(1011, 2) // "11"
b = new BigNumber('zz.9', 36) // "1295.25"
c = x.plus(y) // "1306.25"
```
Note that a BigNumber is created from a Number's decimal `toString()` value not from its underlying binary value. If the latter is required, then pass the Number's `toString(2)` value and specify base 2.
```javascript
new BigNumber(Number.MAX_VALUE.toString(2), 2)
```
If the limited precision of Number values is not well understood, **it is recommended to pass String values rather than Number values** to avoid a potential loss of precision.
```javascript
// Precision loss from using numeric literals with more than 15 significant digits.
new BigNumber(1.0000000000000001); // '1'
new BigNumber(88259496234518.57); // '88259496234518.56'
new BigNumber(99999999999999999999); // '100000000000000000000'
// Precision loss from using numeric literals outside the range of Number values.
new BigNumber(2e+308); // 'Infinity'
new BigNumber(1e-324); // '0'
// Precision loss from the unexpected result of arithmetic with Number values.
new BigNumber(0.7 + 0.1); // '0.7999999999999999'
```
A BigNumber is immutable in the sense that it is not changed by its methods.
```javascript
0.3 - 0.1 // 0.19999999999999998
x = new BigNumber(0.3)
x.minus(0.1) // "0.2"
x // "0.3"
```
The methods that return a BigNumber can be chained.
```javascript
x.dividedBy(y).plus(z).times(9)
x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').integerValue()
```
Some of the longer method names have a shorter alias.
```javascript
x.squareRoot().dividedBy(y).exponentiatedBy(3).isEqualTo( x.sqrt().div(y).pow(3) ) // true
x.modulo(y).multipliedBy(z).eq( x.mod(y).times(z) ) // true
```
As with JavaScript's Number type, there are `toExponential`, `toFixed` and `toPrecision` methods
```javascript
x = new BigNumber(255.5)
x.toExponential(5) // "2.55500e+2"
x.toFixed(5) // "255.50000"
x.toPrecision(5) // "255.50"
x.toNumber() // 255.5
```
and a base can be specified for `toString`.
```javascript
x.toString(16) // "ff.8"
```
There is also a `toFormat` method which may be useful for internationalisation
```javascript
y = new BigNumber('1234567.898765')
y.toFormat(2) // "1,234,567.90"
```
The maximum number of decimal places of the result of an operation involving division (i.e. a division, square root, base conversion or negative power operation) is set using the `config` method of the `BigNumber` constructor.
The other arithmetic operations always give the exact result.
```javascript
BigNumber.config({ DECIMAL_PLACES: 10, ROUNDING_MODE: 4 })
x = new BigNumber(2);
y = new BigNumber(3);
z = x.dividedBy(y) // "0.6666666667"
z.squareRoot() // "0.8164965809"
z.exponentiatedBy(-3) // "3.3749999995"
z.toString(2) // "0.1010101011"
z.multipliedBy(z) // "0.44444444448888888889"
z.multipliedBy(z).decimalPlaces(10) // "0.4444444445"
```
There is a `toFraction` method with an optional *maximum denominator* argument
```javascript
y = new BigNumber(355)
pi = y.dividedBy(113) // "3.1415929204"
pi.toFraction() // [ "7853982301", "2500000000" ]
pi.toFraction(1000) // [ "355", "113" ]
```
and `isNaN` and `isFinite` methods, as `NaN` and `Infinity` are valid `BigNumber` values.
```javascript
x = new BigNumber(NaN) // "NaN"
y = new BigNumber(Infinity) // "Infinity"
x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite() // true
```
The value of a BigNumber is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
```javascript
x = new BigNumber(-123.456);
x.c // [ 123, 45600000000000 ] coefficient (i.e. significand)
x.e // 2 exponent
x.s // -1 sign
```
For advanced usage, multiple BigNumber constructors can be created, each with their own independent configuration which applies to all BigNumber's created from it.
```javascript
// Set DECIMAL_PLACES for the original BigNumber constructor
BigNumber.config({ DECIMAL_PLACES: 10 })
// Create another BigNumber constructor, optionally passing in a configuration object
BN = BigNumber.clone({ DECIMAL_PLACES: 5 })
x = new BigNumber(1)
y = new BN(1)
x.div(3) // '0.3333333333'
y.div(3) // '0.33333'
```
For futher information see the [API](http://mikemcl.github.io/bignumber.js/) reference in the *doc* directory.
## Test
The *test/modules* directory contains the test scripts for each method.
The tests can be run with Node.js or a browser. For Node.js use
$ npm test
or
$ node test/test
To test a single method, use, for example
$ node test/methods/toFraction
For the browser, open *test/test.html*.
## Performance
See the [README](https://github.com/MikeMcl/bignumber.js/tree/master/perf) in the *perf* directory.
## Build
For Node, if [uglify-js](https://github.com/mishoo/UglifyJS2) is installed
npm install uglify-js -g
then
npm run build
will create *bignumber.min.js*.
A source map will also be created in the root directory.

# buffer-equal-constant-time
Constant-time `Buffer` comparison for node.js. Should work with browserify too.
[![Build Status](https://travis-ci.org/goinstant/buffer-equal-constant-time.png?branch=master)](https://travis-ci.org/goinstant/buffer-equal-constant-time)
```sh
npm install buffer-equal-constant-time
```
# Usage
```js
var bufferEq = require('buffer-equal-constant-time');
var a = new Buffer('asdf');
var b = new Buffer('asdf');
if (bufferEq(a,b)) {
// the same!
} else {
// different in at least one byte!
}
```
If you'd like to install an `.equal()` method onto the node.js `Buffer` and
`SlowBuffer` prototypes:
```js
require('buffer-equal-constant-time').install();
var a = new Buffer('asdf');
var b = new Buffer('asdf');
if (a.equal(b)) {
// the same!
} else {
// different in at least one byte!
}
```
To get rid of the installed `.equal()` method, call `.restore()`:
```js
require('buffer-equal-constant-time').restore();
```

# ecdsa-sig-formatter
[![Build Status](https://travis-ci.org/Brightspace/node-ecdsa-sig-formatter.svg?branch=master)](https://travis-ci.org/Brightspace/node-ecdsa-sig-formatter) [![Coverage Status](https://coveralls.io/repos/Brightspace/node-ecdsa-sig-formatter/badge.svg)](https://coveralls.io/r/Brightspace/node-ecdsa-sig-formatter)
Translate between JOSE and ASN.1/DER encodings for ECDSA signatures
## Install
```sh
npm install ecdsa-sig-formatter --save
```
## Usage
```js
var format = require('ecdsa-sig-formatter');
var derSignature = '..'; // asn.1/DER encoded ecdsa signature
var joseSignature = format.derToJose(derSignature);
```
### API
---
#### `.derToJose(Buffer|String signature, String alg)` -> `String`
Convert the ASN.1/DER encoded signature to a JOSE-style concatenated signature.
Returns a _base64 url_ encoded `String`.
* If _signature_ is a `String`, it should be _base64_ encoded
* _alg_ must be one of _ES256_, _ES384_ or _ES512_
---
#### `.joseToDer(Buffer|String signature, String alg)` -> `Buffer`
Convert the JOSE-style concatenated signature to an ASN.1/DER encoded
signature. Returns a `Buffer`
* If _signature_ is a `String`, it should be _base64 url_ encoded
* _alg_ must be one of _ES256_, _ES384_ or _ES512_

# 3.0.1
* no longer include dist/test in npm releases
# 3.0.0
* use nextTick() instead of setImmediate() to schedule microtasks with node 0.10. Later versions of
nodes are not affected as they were already using nextTick(). Note that using nextTick() might
trigger a depreciation warning on 0.10 as described at https://github.com/cujojs/when/issues/410.
The reason why nextTick() is preferred is that is setImmediate() would schedule a macrotask
instead of a microtask and might result in a different scheduling.
If needed you can revert to the former behavior as follow:
var Promise = require('es6-promise').Promise;
Promise._setScheduler(setImmediate);

# ES6-Promise (subset of [rsvp.js](https://github.com/tildeio/rsvp.js)) [![Build Status](https://travis-ci.org/stefanpenner/es6-promise.svg?branch=master)](https://travis-ci.org/stefanpenner/es6-promise)
This is a polyfill of the [ES6 Promise](http://www.ecma-international.org/ecma-262/6.0/#sec-promise-constructor). The implementation is a subset of [rsvp.js](https://github.com/tildeio/rsvp.js) extracted by @jakearchibald, if you're wanting extra features and more debugging options, check out the [full library](https://github.com/tildeio/rsvp.js).
For API details and how to use promises, see the <a href="http://www.html5rocks.com/en/tutorials/es6/promises/">JavaScript Promises HTML5Rocks article</a>.

## CDN
To use via a CDN include this in your html:
```html
<!-- Automatically provides/replaces `Promise` if missing or broken. -->
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.js"></script>
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.auto.js"></script>
<!-- Minified version of `es6-promise-auto` below. -->
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.auto.min.js"></script>
```
## Node.js
To install:
```sh
yarn add es6-promise
```
or
```sh
npm install es6-promise
```
To use:
```js
var Promise = require('es6-promise').Promise;
```
## Usage in IE<9
`catch` and `finally` are reserved keywords in IE<9, meaning
`promise.catch(func)` or `promise.finally(func)` throw a syntax error. To work
around this, you can use a string to access the property as shown in the
following example.
However most minifiers will automatically fix this for you, making the
resulting code safe for old browsers and production:
```js
promise['catch'](function(err) {
// ...
});
```
```js
promise['finally'](function() {
// ...
});
```
## Auto-polyfill
To polyfill the global environment (either in Node or in the browser via CommonJS) use the following code snippet:
```js
require('es6-promise').polyfill();
```
Alternatively
```js
require('es6-promise/auto');
```
Notice that we don't assign the result of `polyfill()` to any variable. The `polyfill()` method will patch the global environment (in this case to the `Promise` name) when called.
## Building & Testing
You will need to have PhantomJS installed globally in order to run the tests.
`npm install -g phantomjs`
* `npm run build` to build
* `npm test` to run tests
* `npm start` to run a build watcher, and webserver to test
* `npm run test:server` for a testem test runner and watching builder
// This file can be required in Browserify and Node.js for automatic polyfill
// To use it: require('es6-promise/auto');
'use strict';
module.exports = require('./').polyfill();

/**
Promise objects represent the eventual result of an asynchronous operation. The
primary way of interacting with a promise is through its `then` method, which
registers callbacks to receive either a promise's eventual value or the reason
why the promise cannot be fulfilled.
Terminology
-----------
- `promise` is an object or function with a `then` method whose behavior conforms to this specification.
- `thenable` is an object or function that defines a `then` method.
- `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
- `exception` is a value that is thrown using the throw statement.
- `reason` is a value that indicates why a promise was rejected.
- `settled` the final resting state of a promise, fulfilled or rejected.
A promise can be in one of three states: pending, fulfilled, or rejected.
Promises that are fulfilled have a fulfillment value and are in the fulfilled
state. Promises that are rejected have a rejection reason and are in the
rejected state. A fulfillment value is never a thenable.
Promises can also be said to *resolve* a value. If this value is also a
promise, then the original promise's settled state will match the value's
settled state. So a promise that *resolves* a promise that rejects will
itself reject, and a promise that *resolves* a promise that fulfills will
itself fulfill.
Basic Usage:
------------
```js
let promise = new Promise(function(resolve, reject) {
// on success
resolve(value);
// on failure
reject(reason);
});
promise.then(function(value) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Advanced Usage:
---------------
Promises shine when abstracting away asynchronous interactions such as
`XMLHttpRequest`s.
```js
function getJSON(url) {
return new Promise(function(resolve, reject){
let xhr = new XMLHttpRequest();
xhr.open('GET', url);
xhr.onreadystatechange = handler;
xhr.responseType = 'json';
xhr.setRequestHeader('Accept', 'application/json');
xhr.send();
function handler() {
if (this.readyState === this.DONE) {
if (this.status === 200) {
resolve(this.response);
} else {
reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
}
}
};
});
}
getJSON('/posts.json').then(function(json) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Unlike callbacks, promises are great composable primitives.
```js
Promise.all([
getJSON('/posts'),
getJSON('/comments')
]).then(function(values){
values[0] // => postsJSON
values[1] // => commentsJSON
return values;
});
```
@class Promise
@param {Function} resolver
Useful for tooling.
@constructor
*/
class Promise {
constructor(resolver) {
this[PROMISE_ID] = nextId();
this._result = this._state = undefined;
this._subscribers = [];
if (noop !== resolver) {
typeof resolver !== 'function' && needsResolver();
this instanceof Promise ? initializePromise(this, resolver) : needsNew();
}
}
/**
The primary way of interacting with a promise is through its `then` method,
which registers callbacks to receive either a promise's eventual value or the
reason why the promise cannot be fulfilled.
```js
findUser().then(function(user){
// user is available
}, function(reason){
// user is unavailable, and you are given the reason why
});
```
Chaining
--------
The return value of `then` is itself a promise. This second, 'downstream'
promise is resolved with the return value of the first promise's fulfillment
or rejection handler, or rejected if the handler throws an exception.
```js
findUser().then(function (user) {
return user.name;
}, function (reason) {
return 'default name';
}).then(function (userName) {
// If `findUser` fulfilled, `userName` will be the user's name, otherwise it
// will be `'default name'`
});
findUser().then(function (user) {
throw new Error('Found user, but still unhappy');
}, function (reason) {
throw new Error('`findUser` rejected and we're unhappy');
}).then(function (value) {
// never reached
}, function (reason) {
// if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
// If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
});
```
If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
```js
findUser().then(function (user) {
throw new PedagogicalException('Upstream error');
}).then(function (value) {
// never reached
}).then(function (value) {
// never reached
}, function (reason) {
// The `PedgagocialException` is propagated all the way down to here
});
```
Assimilation
------------
Sometimes the value you want to propagate to a downstream promise can only be
retrieved asynchronously. This can be achieved by returning a promise in the
fulfillment or rejection handler. The downstream promise will then be pending
until the returned promise is settled. This is called *assimilation*.
```js
findUser().then(function (user) {
return findCommentsByAuthor(user);
}).then(function (comments) {
// The user's comments are now available
});
```
If the assimliated promise rejects, then the downstream promise will also reject.
```js
findUser().then(function (user) {
return findCommentsByAuthor(user);
}).then(function (comments) {
// If `findCommentsByAuthor` fulfills, we'll have the value here
}, function (reason) {
// If `findCommentsByAuthor` rejects, we'll have the reason here
});
```
Simple Example
--------------
Synchronous Example
```javascript
let result;
try {
result = findResult();
// success
} catch(reason) {
// failure
}
```
Errback Example
```js
findResult(function(result, err){
if (err) {
// failure
} else {
// success
}
});
```
Promise Example;
```javascript
findResult().then(function(result){
// success
}, function(reason){
// failure
});
```
Advanced Example
--------------
Synchronous Example
```javascript
let author, books;
try {
author = findAuthor();
books = findBooksByAuthor(author);
// success
} catch(reason) {
// failure
}
```
Errback Example
```js
function foundBooks(books) {
}
function failure(reason) {
}
findAuthor(function(author, err){
if (err) {
failure(err);
// failure
} else {
try {
findBoooksByAuthor(author, function(books, err) {
if (err) {
failure(err);
} else {
try {
foundBooks(books);
} catch(reason) {
failure(reason);
}
}
});
} catch(error) {
failure(err);
}
// success
}
});
```
Promise Example;
```javascript

then(findBooksByAuthor).
then(function(books){
// found books

// something went wrong
});

`Promise.all` accepts an array of promises, and returns a new promise which
is fulfilled with an array of fulfillment values for the passed promises, or
rejected with the reason of the first passed promise to be rejected. It casts all
elements of the passed iterable to promises as it runs this algorithm.
Example:

If any of the `promises` given to `all` are rejected, the first promise
that is rejected will be given as an argument to the returned promises's
rejection handler. For example:
Example:
```javascript

let promise2 = reject(new Error("2"));
let promise3 = reject(new Error("3"));
let promises = [ promise1, promise2, promise3 ];
Promise.all(promises).then(function(array){

`Promise.race` returns a new promise which is settled in the same way as the
first passed promise to settle.
Example:
```javascript
let promise1 = new Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 1');
}, 200);
});
let promise2 = new Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 2');
}, 100);
});
Promise.race([promise1, promise2]).then(function(result){
// result === 'promise 2' because it was resolved before promise1
// was resolved.
});
```
`Promise.race` is deterministic in that only the state of the first
settled promise matters. For example, even if other promises given to the
`promises` array argument are resolved, but the first settled promise has
become rejected before the other promises became fulfilled, the returned
promise will become rejected:
```javascript
let promise1 = new Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 1');
}, 200);
});
let promise2 = new Promise(function(resolve, reject){
setTimeout(function(){
reject(new Error('promise 2'));
}, 100);
});
Promise.race([promise1, promise2]).then(function(result){
// Code here never runs
}, function(reason){
// reason.message === 'promise 2' because promise 2 became rejected before
// promise 1 became fulfilled
});
```
An example real-world use case is implementing timeouts:
```javascript
Promise.race([ajax('foo.json'), timeout(5000)])
```

# es6-promisify
Converts callback-based functions to Promise-based functions.
## Install
Install with [npm](https://npmjs.org/package/es6-promisify)
```bash
npm install --save es6-promisify
```
## Example
```js
"use strict";
// Declare variables
const promisify = require("es6-promisify");
const fs = require("fs");
// Convert the stat function
const stat = promisify(fs.stat);
// Now usable as a promise!
stat("example.txt").then(function (stats) {
console.log("Got stats", stats);
}).catch(function (err) {
console.error("Yikes!", err);
});
```
## Promisify methods
```js
"use strict";
// Declare variables
const promisify = require("es6-promisify");
const redis = require("redis").createClient(6379, "localhost");
// Create a promise-based version of send_command
const client = promisify(redis.send_command, redis);
// Send commands to redis and get a promise back
client("ping").then(function (pong) {
console.log("Got", pong);
}).catch(function (err) {
console.error("Unexpected error", err);
}).then(function () {
redis.quit();
});
```
## Handle callback multiple arguments
```js
"use strict";
// Declare functions
function test(cb) {
return cb(undefined, 1, 2, 3);
}
// Declare variables
const promisify = require("es6-promisify");
// Create promise-based version of test
const single = promisify(test);
const multi = promisify(test, {multiArgs: true});
// Discards additional arguments
single().then(function (result) {
console.log(result); // 1
});
// Returns all arguments as an array
multi().then(function (result) {
console.log(result); // [1, 2, 3]
});
```
### Tests
Test with nodeunit
