## What it is
A Vite and Rollup plugin that implements Module Federation, allowing multiple frontend applications to share code and modules at runtime. It is inspired by and compatible with Webpack Module Federation.

## Use cases
- share components between multiple frontend apps at runtime
- build a micro-frontend architecture with Vite
- load remote modules from another app in a Vite project
- share dependencies like Vue across separate builds
- migrate Webpack Module Federation to Vite or Rollup
- expose modules from a remote app to a host app

## When to choose
- you use Vite or Rollup and want Webpack-compatible Module Federation
- you are splitting a monolithic frontend into micro-frontends
- you need runtime code sharing between independently deployed frontend apps

## When to avoid
- you are using Webpack, which has built-in Module Federation
- you only need simple static code sharing via npm packages
- you need a framework-agnostic micro-frontend runtime beyond Vite/Rollup
