Micro-frontends building blocks: Webpack Module Federation

• webpack

  331 64,179 9.8 JavaScript

  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.

  

Module Federation was created by Zack Jackson, a Webpack core maintainer himself, and was integrated as a flagship feature of Webpack 5 in October 2020.

Later on, it was extended to support server-side rendering scenarios. Since the method I'm going to explore in building my micro-frontends is client-side composition using React.js, I've identified Module Federation as the perfect technology to use.

• Next.js
