## Basic Information

- **Project Name**: webpack
- **Description**: A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
- **Primary Language**: Unknown

# Introduction

webpack is a bundler for modules. The main purpose is to bundle javascript files for usage in browser.

**TL;DR**

* bundles [CommonJs](http://www.commonjs.org/specs/modules/1.0/), [AMD](https://github.com/amdjs/amdjs-api/wiki/AMD) and/or [Labeled Modules](https://github.com/labeledmodules/labeled-modules-spec/wiki) modules. (even combined)
* can create a single bundle or a bunch of chunks loaded on demand, to reduce initial loading time.
* dependencies are resolved while compiling, this makes the runtime very small
* loader can preprocess files while compiling, i. e. coffee-script to javascript

Check the [documentation](https://github.com/webpack/docs/wiki) if you want to know more...

# Examples

Take a look at the [`examples`](https://github.com/webpack/webpack/tree/master/examples) folder.

# Features

* loaders are chainable
* loaders run in node.js and can do a bunch of stuff
* option to name your file with a hash of the content
* watch mode
* SourceUrl and SourceMap support
* plugin system, extend webpack or build a complete different compiler
 * i. e. [component](https://github.com/webpack/component-webpack-plugin), [rewire](https://github.com/jhnns/rewire-webpack) and [more...](https://github.com/webpack/docs/wiki/webpack-plugins)
* [interfaces](https://github.com/webpack/docs/wiki/webpack-usage)
 * CLI with [arguments](https://github.com/webpack/docs/wiki/webpack-detailed-usage)
 * CLI with [config file](https://github.com/webpack/docs/wiki/webpack-options), [arguments](https://github.com/webpack/docs/wiki/webpack-detailed-usage) are still possible
 * usable as library from node.js
 * usable as [grunt plugin](https://github.com/webpack/grunt-webpack)
* browser replacements
 * comes with browser replacements for some node.js modules
* see also
 * [webpack-dev-middleware](https://github.com/webpack/webpack-dev-middleware)
 * [webpack-dev-server](https://github.com/webpack/webpack-dev-server)
 * [enhanced-resolve](https://github.com/webpack/enhanced-resolve) and
 * [enhanced-require](https://github.com/webpack/enhanced-require)

## A small example what's possible

``` javascript
var commonjs = require("./commonjs");
require: "./labeled";
define(["amd-module", "./file"], function(amdModule, file) {
	require(["big-module/big/file"], function(big) {
		// AMD require acts as split point
		// and "big-module/big/file" is only downloaded when requested
		var stuff = require("../my/stuff");
		// dependencies automatically goes in chunk too
	});
});

require("coffee!./cup.coffee");
// The loader syntax allows to proprocess files
// for common stuff you can bind RegExps to loaders
// if you also add ".coffee" to the default extensions
// you can write:
require("./cup");

function loadTemplate(name) {
	return require("./templates/" + name ".jade");
	// dynamic requires are supported
	// while compiling we figure out what can be requested
	// here everything in "./templates" that matches /^.*\.jade$/
	// (can also be in subdirectories)
}

require("imports?_=underscore!../loaders/my-ejs-loader!./template.html");
// you can chain loaders
// you can configure loaders with query parameters
// and loaders resolve similar to modules

// ...you can combine everything
function loadTemplateAsync(name, callback) {
	require(["bundle?lazy!./templates/" + name + ".jade"], function(templateBundle) {
		templateBundle(callback);
	});
}
```

## Tests

You can run the unit tests with `npm test`. [![build status](https://secure.travis-ci.org/webpack/webpack.png)](http://travis-ci.org/webpack/webpack)

You can run the browser tests:

```
cd test/browsertests
node build
```

and open `tests.html` in browser.



## Contribution

You are welcome to contribute by writing issues or pull requests.
It would be nice if you open source your own loaders or webmodules. :)

You are also welcome to correct any spelling mistakes or any language issues, because my english is not perfect...
