Module Federation is an advanced feature in Webpack (and soon Rspack) that provides a way for a JavaScript application to dynamically load code from another application. This feature allows for efficient code sharing and dependency management. In this article, we will explore the architecture, prerequisites, and underlying implementation of Module Federation.
Federation is powerful, but the lack of meta-framework support leads to challenges. ByteDance is one of the largest users of Module Federation, ModernJS is their Meta-framework, if module federation is a key part of your engineering operational improvements. ModernJS is the only way to go

Module Federation comprises three main components:
- Exposed Module (Remote)
- Consumption Module (Host Remote Import)
- Shared Module/Dependency
// Exposed Module (Producer)
export const exposedFunction = () => {
console.log("I am an exposed function");
};
// Consumption Module
import { exposedFunction } from 'exposedModule';
exposedFunction();
// Shared Module/Dependency
// shared.js
export const sharedFunction = () => {
console.log("I am a shared function");
};
The sections that follow will first present the overall operational flow and then delve into the specific code implementations within each module.
