Angular Remote Application

Angular Remote Application Overview

At its core, angular remote application is about doing one thing well inside your Module Federation project. Once you understand the pattern, you can apply it consistently across features and teams.

Good angular remote application pays off across the whole codebase: fewer surprises, easier testing, and smoother onboarding. The snippet below is a solid starting point.

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

module.exports = {
  plugins: [
    new ModuleFederationPlugin({
      name: 'catalog',
      filename: 'remoteEntry.js',
      exposes: {
        './ProductList': './src/ProductList',
      },
      shared: ['react', 'react-dom'],
    }),
  ],
};

A remote exposes modules through remoteEntry.js so hosts can load them at runtime.

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

How Angular Remote Application Works in Module Federation

Angular Remote Application 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.

A remote exposes modules through remoteEntry.js so hosts can load them at runtime.

• 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 Angular Remote Application

In production, angular remote application 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 angular remote application.
• Leaving angular remote application untested, so regressions slip into production.
• Over-engineering angular remote application before you actually need the extra flexibility.
• Ignoring documentation, which makes angular remote application hard for the next developer to change.

Key Takeaways

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