# node-libs-browser
The node core libs for in-browser usage.
NOTE: This library is deprecated and won't accept Pull Requests that include Breaking Changes or new Features. Only bugfixes are accepted.
[![dependencies status](http://david-dm.org/webpack/node-libs-browser.png)](http://david-dm.org/webpack/node-libs-browser)
Exports a hash [object] of absolute paths to each lib, keyed by lib names. Modules without browser replacements are `null`.
Some modules have mocks in the `mock` directory. These are replacements with minimal functionality.

## Outdated versions
### `buffer`
The current `buffer` implementation uses feross/buffer@4.x because feross/buffer@5.x relies on [typed arrays](https://github.com/feross/buffer/commit/5daca86b7cd5d2b8ccb167534d47421029f639e9#commitcomment-19698936).
This will be dropped as soon as IE9 is not a typical browser target anymore.
### `punycode`
The current `punycode` implementation uses bestiejs/punycode.js@1.x because bestiejs/punycode.js@2.x requires modern JS engines that understand `const` and `let`.
It will be removed someday since it has already been [deprecated from the node API](https://nodejs.org/api/punycode.html).

# Punycode.js [![Build status](https://travis-ci.org/bestiejs/punycode.js.svg?branch=master)](https://travis-ci.org/bestiejs/punycode.js) [![Code coverage status](http://img.shields.io/coveralls/bestiejs/punycode.js/master.svg)](https://coveralls.io/r/bestiejs/punycode.js) [![Dependency status](https://gemnasium.com/bestiejs/punycode.js.svg)](https://gemnasium.com/bestiejs/punycode.js)
A robust Punycode converter that fully complies to [RFC 3492](https://tools.ietf.org/html/rfc3492) and [RFC 5891](https://tools.ietf.org/html/rfc5891), and works on nearly all JavaScript platforms.
This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
* [The C example code from RFC 3492](https://tools.ietf.org/html/rfc3492#appendix-C)
* [`punycode.c` by _Markus W. Scherer_ (IBM)](http://opensource.apple.com/source/ICU/ICU-400.42/icuSources/common/punycode.c)
* [`punycode.c` by _Ben Noordhuis_](https://github.com/bnoordhuis/punycode/blob/master/punycode.c)
* [JavaScript implementation by _some_](http://stackoverflow.com/questions/183485/can-anyone-recommend-a-good-free-javascript-for-punycode-to-unicode-conversion/301287#301287)
* [`punycode.js` by _Ben Noordhuis_](https://github.com/joyent/node/blob/426298c8c1c0d5b5224ac3658c41e7c2a3fe9377/lib/punycode.js) (note: [not fully compliant](https://github.com/joyent/node/issues/2072))
This project is [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with [Node.js v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc) and [io.js v1.0.0+](https://github.com/iojs/io.js/blob/v1.x/lib/punycode.js).
## Installation
Via [npm](https://www.npmjs.com/) (only required for Node.js releases older than v0.6.2):
```bash
npm install punycode
```
Via [Bower](http://bower.io/):
```bash
bower install punycode
```
Via [Component](https://github.com/component/component):
```bash
component install bestiejs/punycode.js
```
In a browser:
```html
<script src="punycode.js"></script>
```
In [Node.js](https://nodejs.org/), [io.js](https://iojs.org/), [Narwhal](http://narwhaljs.org/), and [RingoJS](http://ringojs.org/):
```js
var punycode = require('punycode');
```
In [Rhino](http://www.mozilla.org/rhino/):
```js
load('punycode.js');
```
Using an AMD loader like [RequireJS](http://requirejs.org/):
```js
require(
{
'paths': {
'punycode': 'path/to/punycode'
}
},
['punycode'],
function(punycode) {
console.log(punycode);
}
);
```
## API
### `punycode.decode(string)`
Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
```js
// decode domain name parts
punycode.decode('maana-pta'); // 'mañana'
punycode.decode('--dqo34k'); // '☃-⌘'
```
### `punycode.encode(string)`
Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
```js
// encode domain name parts
punycode.encode('mañana'); // 'maana-pta'
punycode.encode('☃-⌘'); // '--dqo34k'
```
### `punycode.toUnicode(input)`
Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesnt matter if you call it on a string that has already been converted to Unicode.
```js
// decode domain names
punycode.toUnicode('xn--maana-pta.com');
// → 'mañana.com'
punycode.toUnicode('xn----dqo34k.com');
// → '☃-⌘.com'
// decode email addresses
punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
// → 'джумла@джpумлатест.bрфa'
```
### `punycode.toASCII(input)`
Converts a lowercased Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesnt matter if you call it with a domain thats already in ASCII.
```js
// encode domain names
punycode.toASCII('mañana.com');
// → 'xn--maana-pta.com'
punycode.toASCII('☃-⌘.com');
// → 'xn----dqo34k.com'
// encode email addresses
punycode.toASCII('джумла@джpумлатест.bрфa');
// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
```
### `punycode.ucs2`
#### `punycode.ucs2.decode(string)`
Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
```js
punycode.ucs2.decode('abc');
// → [0x61, 0x62, 0x63]
// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
punycode.ucs2.decode('\uD834\uDF06');
// → [0x1D306]
```
#### `punycode.ucs2.encode(codePoints)`
Creates a string based on an array of numeric code point values.
```js
punycode.ucs2.encode([0x61, 0x62, 0x63]);
// → 'abc'
punycode.ucs2.encode([0x1D306]);
// → '\uD834\uDF06'
```
### `punycode.version`
A string representing the current Punycode.js version number.
## Unit tests & code coverage
After cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
Once thats done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.
To generate the code coverage report, use `grunt cover`.
Feel free to fork if you see possible improvements!

# util [![Build Status](https://travis-ci.org/defunctzombie/node-util.png?branch=master)](https://travis-ci.org/defunctzombie/node-util)
> Node.js's [util][util] module for all engines.
This implements the Node.js [`util`][util] module for environments that do not have it, like browsers.
## Install
You usually do not have to install `util` yourself. If your code runs in Node.js, `util` is built in. If your code runs in the browser, bundlers like [browserify](https://github.com/browserify/browserify) or [webpack](https://github.com/webpack/webpack) also include the `util` module.
But if none of those apply, with npm do:
```shell
npm install util
```
## Usage
```javascript
var util = require('util')
var EventEmitter = require('events')
function MyClass() { EventEmitter.call(this) }
util.inherits(MyClass, EventEmitter)
```
## Browser Support
The `util` module uses ES5 features. If you need to support very old browsers like IE8, use a shim like [`es5-shim`](https://www.npmjs.com/package/es5-shim). You need both the shim and the sham versions of `es5-shim`.
To use `util.promisify` and `util.callbackify`, Promises must already be available. If you need to support browsers like IE11 that do not support Promises, use a shim. [es6-promise](https://github.com/stefanpenner/es6-promise) is a popular one but there are many others available on npm.
## API
See the [Node.js util docs][util]. `util` currently supports the Node 8 LTS API. However, some of the methods are outdated. The `inspect` and `format` methods included in this module are a lot more simple and barebones than the ones in Node.js.
## Contributing
PRs are very welcome! The main way to contribute to `util` is by porting features, bugfixes and tests from Node.js. Ideally, code contributions to this module are copy-pasted from Node.js and transpiled to ES5, rather than reimplemented from scratch. Matching the Node.js code as closely as possible makes maintenance simpler when new changes land in Node.js.
This module intends to provide exactly the same API as Node.js, so features that are not available in the core `util` module will not be accepted. Feature requests should instead be directed at [nodejs/node](https://github.com/nodejs/node) and will be added to this module once they are implemented in Node.js.
If there is a difference in behaviour between Node.js's `util` module and this module, please open an issue!
