## What it is
EMP is a micro-frontend engineering framework built on Rspack 2 and Module Federation 2, providing unified configuration for host/remote apps, shared dependencies, manifest and DTS generation. It supports React, Vue 2/3, and modern CSS tooling with ESM-first output.

## Use cases
- build a micro-frontend architecture with module federation
- share dependencies between independently deployed frontend apps
- split a large React or Vue app into federated remote modules
- generate TypeScript type declarations for federated modules
- migrate a webpack module federation setup to Rspack for faster builds

## When to choose
- you need micro-frontend federation with shared dependencies and runtime loading
- you want a batteries-included build setup for host and remote apps
- you want fast Rspack-based builds with ESM output

## When to avoid
- you need a simple single-page app without module federation
- you require a permissive license for enterprise use since the repo has no license
- you prefer framework-agnostic tooling outside the EMP configuration model
