webpack is a module bundler.

This means webpack takes modules with dependencies and emit static assets representing that modules.

modules with dependencies ---webpack---> static assets

Why another module bundler?

Existing module bundlers are not well suited for big projects (big single page application). The most pressing reason for developing another module bundler was Code Splitting. Another one was that other static assets should fit seamless in the modularization.

I tried to extend existing module bundlers, but it wasn't possible to archive all goals.

Goals

  • Split the dependency tree into chunks, that are loaded on demand
  • Every static asset should be able to be a module
  • Keep initial loading time low
  • Ability to integrate 3rd-party libraries as modules
  • Ability to customize nearly every part of the module bundler
  • Suited for big projects

webpack 👍
