JavaScript Module Federation: Micro-Frontends in Practice

Tue, 09 Jul 2024 00:00:00 +0900

Introduction

Module Federation, introduced in Webpack 5, provides a runtime integration mechanism for building micro-frontend architectures. Unlike build-time integration approaches, it enables independently deployed applications to share code at runtime, facilitating team autonomy and incremental migration without coordinated releases.

At its core, Module Federation allows a JavaScript application to dynamically load code from another application at runtime. Each participating application exposes a remoteEntry.js file that serves as the entry point. When a host application needs a component from a remote, it fetches the remoteEntry.js at runtime and resolves the required module on demand.
