Simple example demonstrating Module Federation in Webpack 5. Companion repository for my React Bangalore Meetup talk.

Module Federation Demo

A very simple demo for an application using Webpack Module Federation. Intended as a companion repository for my talk at the React Bangalore Meetup.

Codebase Organization

Here, we are using a yarn workspaces monorepo structure for demonstration. We have two packages app-1 and app-2. In the real world, these two packages would most likely live in their own separate repositories and would be developed, tested, and deployed independently of each other.

In our case, app-1 is the host, and app-2 is the remote. We are exposing a component named AppTwoComponent from app-2. This component would be dynamically loaded at runtime when app-1 starts.

    ├── app-1
    └── app-2

Running the demo locally

• Step 1: Install dependencies

yarn install

• Step 2: Start both app-1 and app-2

yarn dev

This will start app-1 at localhost:3001 and app-2 at localhost:3002.

• Step 3: View app-1 at localhost:3001
  • Since we are simply exposing the AppTwoComponent from app-2, and nothing else, you won't see anything on localhost:3002.
