Module Federation with Angular

with Angular Overview

with Angular is a building block you will reach for often in Module Federation. It keeps related logic together and makes your intent obvious to reviewers and future maintainers.

When you learn with angular properly, you avoid the guesswork that leads to bugs and rework. The example below shows the shape you will use in most real Module Federation projects.

// bootstrap a federated Angular remote
import { loadRemoteModule } from '@angular-architects/module-federation';

const routes = [{
  path: 'catalog',
  loadChildren: () => loadRemoteModule({
    remoteEntry: 'http://localhost:3001/remoteEntry.js',
    remoteName: 'catalog',
    exposedModule: './Module',
  }).then((m) => m.CatalogModule),
}];

@angular-architects/module-federation wires federated remotes into Angular's router.

with Angular Example

new ModuleFederationPlugin({
  name: 'app',
  filename: 'remoteEntry.js',
  exposes: { './Widget': './src/Widget' },
  remotes: { other: 'other@http://host/remoteEntry.js' },
  shared: { react: { singleton: true } },
});

• Start from a minimal with Angular example and grow it only as needed.
• Keep configuration explicit so with Angular behaves the same in every environment.
• Name things clearly so teammates understand your with Angular at a glance.
• Add tests around with Angular early to lock in expected behaviour.

How with Angular Works in Module Federation

with Angular builds on Module Federation's ability to load code from another independently built and deployed application at runtime. Each app can be a host, a remote, or both.

@angular-architects/module-federation wires federated remotes into Angular's router.

• Remotes expose modules through a remoteEntry.js manifest.
• Hosts declare remotes and import exposed modules dynamically.
• Shared dependencies are deduplicated, ideally as singletons.
• Each micro frontend builds and deploys on its own schedule.

Practical Guidance for with Angular

In production, with angular needs careful version management and graceful failure handling. Align shared dependency versions and always render a fallback when a remote cannot load.

Common Mistakes

• Skipping error handling and edge cases when wiring up with angular.
• Leaving with angular untested, so regressions slip into production.
• Over-engineering with angular before you actually need the extra flexibility.
• Ignoring documentation, which makes with angular hard for the next developer to change.

Key Takeaways

• with Angular is a core part of working effectively with Module Federation.
• Start small and keep with angular focused on a single responsibility.
• Apply consistent patterns so with angular scales across your project.
• Test and document with angular to keep it maintainable over time.
