Overview of WebPack

How is webpack different?

Code Splitting
webpack has two types of dependencies in its dependency tree: sync and async. Async dependencies act as split points and form a new chunk. After the chunk tree is optimized, a file is emitted for each chunk.

webpack can only process JavaScript natively, but loaders are used to transform other resources into JavaScript. By doing so, every resource forms a module.

Clever parsing
webpack has a clever parser that can process nearly every 3rd party library. It even allows expressions in dependencies such as: require("./templates/" + name + ".jade"). It handles the most common module styles: CommonJs and AMD.

Plugin system
webpack features a rich plugin system. Most internal features are based on this plugin system. This allows you to customize webpack for your needs and distribute common plugins as open source.
