Vue Host Application

Vue Host Application Overview

Vue Host Application 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 vue host application 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.

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

module.exports = {
  plugins: [
    new ModuleFederationPlugin({
      name: 'shell',
      remotes: {
        catalog: 'catalog@http://localhost:3001/remoteEntry.js',
      },
      shared: ['react', 'react-dom'],
    }),
  ],
};

// usage
const ProductList = React.lazy(() => import('catalog/ProductList'));

The host declares remotes by URL and lazy-loads exposed modules like any dynamic import.

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

How Vue Host Application Works in Module Federation

Vue Host 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.

The host declares remotes by URL and lazy-loads exposed modules like any dynamic import.

• 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 Vue Host Application

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

Key Takeaways

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