Module Federation with React

with React Overview

with React lets you structure Module Federation work so it stays readable, testable, and easy to scale. Instead of ad-hoc code, you follow a clear pattern that other developers can recognise immediately.

The key is to keep with react focused and predictable. Start from the minimal example here, then layer in only the complexity your feature actually needs.

import React, { Suspense } from 'react';
const ProductList = React.lazy(() => import('catalog/ProductList'));

export default function App() {
  return (
    <Suspense fallback={<p>Loading...</p>}>
      <ProductList />
    </Suspense>
  );
}

In React, a federated remote is loaded with React.lazy and rendered inside a Suspense boundary.

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

How with React Works in Module Federation

with React 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.

In React, a federated remote is loaded with React.lazy and rendered inside a Suspense boundary.

• 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 React

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

Common Mistakes

• Copying with react snippets without understanding what each line does.
• Skipping error handling and edge cases when wiring up with react.
• Leaving with react untested, so regressions slip into production.
• Over-engineering with react before you actually need the extra flexibility.

Key Takeaways

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