Module Federation

While there are multiple approaches on how to achieve a horizontal split micro-frontend (e.g. iframes, webcomponents) we will use module-federation.

What’s Module Federation

Module federation is a feature, introduced in Webpack 5, that provides the ability to split an application into smaller, independently deployable modules that can be loaded on demand when they are needed.

At its core, Module Federation is based on the idea of remote loading of JavaScript modules. This means that instead of having all the code for a single application loaded at once, the code can be split into smaller, independently deployable modules that can be loaded on demand when they are needed.

Multiple separate builds should form a single application. These separate builds act like containers and can expose and consume code between builds, creating a single, unified application.
