How to Call Vue component inside React Micro Frontend using WebPack 5?

Integrating a Vue component into a React application, especially in a micro frontend architecture using WebPack 5, involves a few key steps. This process can help you leverage the strengths of both Vue and React in your project. Here’s a high-level overview of how you can achieve this integration:

1. Setup Your Micro Frontend Architecture

First, ensure your micro frontend architecture is properly set up. In a micro frontend setup, different parts of your application are developed, deployed, and operated independently. Webpack 5 Module Federation is a popular choice for this purpose as it allows for the seamless integration of various frameworks and libraries in a single application.

2. Create a Vue Component

Develop your Vue component as you normally would. Ensure it’s encapsulated and can run independently. For simplicity, let’s assume you have a simple Vue component named MyVueComponent.

3. Expose Your Vue Component as a Module

Use Webpack’s Module Federation plugin to expose your Vue component. This involves modifying the webpack.config.js file in your Vue application (or wherever your component lives) to add the ModuleFederationPlugin configuration.

Example:

const { ModuleFederationPlugin } = require('webpack').container;

module.exports = {
  plugins: [
    new ModuleFederationPlugin({
      name: 'vueApp',
      filename: 'remoteEntry.js',
      exposes: {
        './MyVueComponent': './src/components/MyVueComponent.vue',
      },
      shared: require('./package.json').dependencies,
    }),
  ],
};

4. Consume the Vue Component in Your React Application

In your React application, modify the webpack.config.js to add the Vue app as a remote:

const { ModuleFederationPlugin } = require('webpack').container;

module.exports = {
  plugins: [
    new ModuleFederationPlugin({
      remotes: {
        vueApp: 'vueApp@http://localhost:3001/remoteEntry.js',
      },
      shared: require('./package.json').dependencies,
    }),
  ],
};

5. Dynamically Import the Vue Component

Use dynamic import() syntax in your React application to load the Vue component. You might need to use a library like @vue/reactivity or a custom wrapper to integrate the Vue component into your React component tree properly.

Example:

import React, { useEffect, useRef } from 'react';

const VueComponentWrapper = () => {
  const containerRef = useRef(null);

  useEffect(() => {
    import('vueApp/MyVueComponent')
      .then((Component) => {
        // Use the Vue component
        // This might involve mounting the Vue component manually
        // and ensuring it's destroyed when the React component unmounts
      })
      .catch((err) => console.error('Error loading the Vue component', err));
  }, []);

  return <div ref={containerRef}></div>;
};

export default VueComponentWrapper;

6. Considerations for Integration

• Lifecycle Management: Make sure to properly handle the lifecycle of the Vue component within your React application. This includes mounting and unmounting the Vue component appropriately.
• State Management: If the Vue component needs to share state with the rest of your React application, consider using a global state management solution or custom events for communication.

This approach leverages Webpack 5’s Module Federation to integrate a Vue component into a React application within a micro frontend architecture. It requires a good understanding of both Vue and React ecosystems, as well as the configuration nuances of Webpack 5.
