Framework Compatibility

single-spa:
single-spa is also framework-agnostic, allowing you to integrate applications built with different frameworks into a single micro frontend architecture.
@angular-architects/module-federation:
@angular-architects/module-federation is specifically designed for Angular applications, providing seamless integration with Angular CLI and Angular's module system.
@module-federation/nextjs-mf:
@module-federation/nextjs-mf is tailored for Next.js applications, leveraging Next.js features like server-side rendering and static site generation while implementing Module Federation.
import-map-overrides:
import-map-overrides is framework-agnostic and can be used with any JavaScript application that supports import maps, making it versatile for various projects.

Code Sharing

single-spa:
single-spa supports code sharing between micro frontends by allowing them to register shared dependencies, ensuring that shared libraries are loaded only once.
@angular-architects/module-federation:
@angular-architects/module-federation enables code sharing between Angular applications by configuring shared modules and components in the Webpack configuration.
@module-federation/nextjs-mf:
@module-federation/nextjs-mf facilitates code sharing between Next.js applications using Module Federation, allowing you to share components and utilities across different Next.js projects.
import-map-overrides:
import-map-overrides allows for dynamic code sharing by modifying the import map at runtime, enabling you to override module paths and share code as needed.

Dynamic Imports

single-spa:
single-spa supports dynamic imports of micro frontends, allowing them to load and unload as needed based on the application's routing and state.
@angular-architects/module-federation:
@angular-architects/module-federation supports dynamic imports of Angular modules, allowing you to load modules on demand and reduce the initial bundle size.
@module-federation/nextjs-mf:
@module-federation/nextjs-mf supports dynamic imports of Next.js components and modules, enabling on-demand loading and improving performance.
import-map-overrides:
import-map-overrides enhances dynamic imports by allowing you to override module paths at runtime, making it easier to test and develop with different module versions.

Routing and Navigation

single-spa:
single-spa provides a robust routing system for micro frontends, allowing you to define routes for each micro frontend and manage navigation between them.
@angular-architects/module-federation:
@angular-architects/module-federation integrates with Angular's routing system, allowing you to define routes for federated modules and navigate between them seamlessly.
@module-federation/nextjs-mf:
@module-federation/nextjs-mf works with Next.js routing, allowing you to define routes for federated components and navigate between them while leveraging Next.js's built-in routing features.
import-map-overrides:
import-map-overrides does not handle routing directly, but it can be used alongside any routing solution to dynamically override module imports based on the current route or application state.

Ease of Use: Code Examples

single-spa:

Single SPA Example

import { registerApplication, start } from 'single-spa';

registerApplication(
  'app1',
  () => import('http://localhost:3001/app1.js'),
  (location) => location.pathname.startsWith('/app1')
);

registerApplication(
  'app2',
  () => import('http://localhost:3002/app2.js'),
  (location) => location.pathname.startsWith('/app2')
);

start();

@angular-architects/module-federation:

Angular Module Federation Example

// webpack.config.js
const ModuleFederationPlugin = require('webpack/lib/container/ModuleFederationPlugin');

module.exports = {
  plugins: [
    new ModuleFederationPlugin({
      name: 'app1',
      filename: 'remoteEntry.js',
      exposes: {
        './Component': './src/app/component/component.ts',
      },
      shared: { angular: { singleton: true } },
    }),
  ],
};

@module-federation/nextjs-mf:

Next.js Module Federation Example

// next.config.js
const { ModuleFederationPlugin } = require('webpack').container;

module.exports = {
  webpack: (config) => {
    config.plugins.push(
      new ModuleFederationPlugin({
        name: 'app2',
        filename: 'remoteEntry.js',
        remotes: {
          app1: 'app1@http://localhost:3001/remoteEntry.js',
        },
        shared: { react: { singleton: true }, 'react-dom': { singleton: true } },
      })
    );
    return config;
  },
};
