Webpack Plugin#

• Can build modules that meet the Module Federation loading specifications.
• Can consume modules that adhere to the Module Federation specifications using aliases.
• Can configure shared dependencies for modules, so that when the host environment of the loaded module already has the corresponding dependency, it will not be loaded again.
• When a module has remote types, it will automatically download and consume the types of the remote modules.
• Consuming remote modules will have hot update capabilities.

Quick Start#

Installation#

You can install the plugin with the following commands:

npm add @module-federation/enhanced --save

Register the Plugin#

In Webpack, you can add the plugin through the plugins configuration item in the webpack.config.js file:

module.exports = {
  devServer: {
    port: 2000,
  },
  output: {
    publicPath: 'http://localhost:2000/', // or auto
  },
  plugins: [
    new ModuleFederationPlugin({
      name: 'webpack_provider',
      filename: 'remoteEntry.js',
      exposes: {
        // Set the modules to be exported, default export as '.'
        './button': './src/components/button',
      },
      shared: {
        react: {
          singleton: true,
        },
        'react-dom': {
          singleton: true,
        },
      },
    }),
  ],
};
