webpack

webpack is a module bundler. Its main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.

Introduction

webpack is a bundler for modules. The main purpose is to bundle JavaScript
files for usage in a browser, yet it is also capable of transforming, bundling,
or packaging just about any resource or asset.

TL;DR

* Bundles ES Modules, CommonJS, and AMD modules (even combined).
* Can create a single bundle or multiple chunks that are asynchronously loaded at runtime (to reduce initial loading time).
* Dependencies are resolved during compilation, reducing the runtime size.
* Loaders can preprocess files while compiling, e.g. TypeScript to JavaScript, Handlebars strings to compiled functions, images to Base64, etc.
* Highly modular plugin system to do whatever else your application requires.

$3

webpack supports all browsers that are ES5-compliant (IE8 and below are not supported).
webpack also needs Promise for import() and require.ensure(). If you want to support older browsers, you will need to load a polyfill before using these expressions.

webpack has a rich plugin
interface. Most of the features
within webpack itself use this plugin interface. This makes webpack very
flexible.

$3

webpack enables use of loaders to preprocess files. This allows you to bundle
any static resource way beyond JavaScript. You can easily write your own
loaders using Node.js.

Loaders are activated by using loadername! prefixes in require() statements,
or are automatically applied via regex from your webpack configuration.
