Most frontend teams hit the same wall. The codebase that felt clean at five developers becomes a coordination nightmare at thirty. Deploys get coupled, releases turn into negotiations, and one team's bug blocks everyone.

Micro Frontends solve this, and Webpack 5 Module Federation is the tool that makes them practical. But almost everything written about it stops at a toy demo. This book does not.

Across 11 chapters, you go from why monolithic frontends break all the way to building and deploying a complete multi-team application: a host shell, a product catalog remote, and a cart remote, fully wired with shared dependencies, routing, cross-MFE communication, error boundaries, and a real deployment setup.

Every code example is production-relevant. No toy snippets. Each one shows code you can use directly or adapt with minimal changes. You will understand not just how Module Federation works, but why it behaves the way it does, so you can debug it confidently when something breaks at 2am.

This is Book 1 of a two-book series. By the end, you will have built and shipped your first production micro frontend.
