Microfrontends is an architectural style that allows web applications to be built as a composition of smaller, independently deployable frontend applications. This lesson will explore how to implement microfrontends using Next.js, a popular React framework.

Microfrontends extend the principles of microservices to the frontend world. Each team can develop, deploy, and maintain a specific part of the application independently. Key benefits include:

• Independent deployment
• Technology agnostic
• Scalability and maintainability

The architecture of microfrontends typically involves:

• Container application: Integrates multiple microfrontends.
• Microfrontends: Individual applications that can be developed in isolation.
• Shared libraries: Common dependencies can be shared to avoid redundancy.

To implement microfrontends with Next.js, follow these steps:

1. Set up a Next.js project for the container application.
2. Create individual Next.js projects for each microfrontend.
3. Integrate microfrontends into the container app using dynamic imports.
4. Handle routing and shared state management, if necessary.

Example of integrating a microfrontend:

import dynamic from 'next/dynamic';

const Microfrontend1 = dynamic(() => import('microfrontend1/Component'));

export default function Home() {
    return (
        

            
Welcome to the Container App
            
        
    );
}
            

When working with microfrontends in Next.js, consider the following best practices:

• Use a module federation setup to share dependencies.
• Keep microfrontends independent to allow for modular development.
• Establish a clear API contract between the container and microfrontends.
