A modern micro-frontend architecture demo in TypeScript using Vite's Module Federatin plugin.

Features in this demo:

• Lazy-loading of microfrontend
• Microfrontend has its own isolated development playground
• Routing and sub-routing with React Router in the parent app and microfrontend
• Microfrontend has its own 404 page
• Micro-frontend takes props and has a type definition defined in the parent app
• Shared component library (Chakra UI) between parent app and microfrontends for UI consistency
• Error Boundary in parent app to catch errors in microfrontend and display a fallback UI
• Microfrontend has it's own environment variables

Features to add:

• Support for multiple environments (development and production)
• Live demo

# Install dependencies in both apps
cd parent && npm install && cd ../mfe1 && npm install

# Serve the micro-frontend at http:https://localhost:5001/
cd mfe1
npm run mfe-preview

# Run the parent app at http:https://localhost:5000/
cd ../parent
npm run dev

Visit: http:https://localhost:5000/ and http:https://localhost:5001/assets/remoteEntry.js

# Run the micro-frontend playground at http:https://localhost:5501/
cd mfe1
npm run dev

Visit: http:https://localhost:5501/

The remoteEntry.js file is not available in this mode because Vite's dev mode is "bundle-less". More info here
