native-federation-typescript

Bundler agnostic plugins to share federated types.

Install

npm i -D @module-federation/native-federation-typescript

This module provides two plugins:

NativeFederationTypeScriptRemote

This plugin is used to build the federated types.

Configuration

{
    moduleFederationConfig: any; // the configuration same configuration provided to the module federation plugin, it is MANDATORY
    tsConfigPath?: string; // path where the tsconfig file is located, default is ''./tsconfig.json'
    typesFolder?: string; // folder where all the files will be stored, default is '@mf-types',
    compiledTypesFolder?: string; // folder where the federated modules types will be stored, default is 'compiled-types'
    deleteTypesFolder?: boolean; // indicate if the types folder will be deleted when the job completes, default is 'true'
    additionalFilesToCompile?: string[] // The path of each additional file which should be emitted
    compilerInstance?: 'tsc' | 'vue-tsc' // The compiler to use to emit files, default is 'tsc'
}

Additional configuration

Note that, for Webpack, the plugin automatically inject the devServer.static.directory configuration.
For the other bundlers, you should configure it by yourself.

NativeFederationTypeScriptHost

This plugin is used to download the federated types.

Configuration

{
    moduleFederationConfig: any; // the configuration same configuration provided to the module federation plugin, it is MANDATORY
    typesFolder?: string; // folder where all the files will be stored, default is '@mf-types',
    deleteTypesFolder?: boolean; // indicate if the types folder will be deleted before the job starts, default is 'true'
    maxRetries?: number; // The number of times the plugin will try to download the types before failing, default is 3
}

Bundler configuration

Vite

// vite.config.ts
import { NativeFederationTypeScriptHost, NativeFederationTypeScriptRemote } from '@module-federation/native-federation-typescript/vite';

export default defineConfig({
  plugins: [
    NativeFederationTypeScriptRemote({
      /* options */
    }),
    NativeFederationTypeScriptHost({
      /* options */
    }),
  ],
  /* ... */
  server: {
    // This is needed to emulate the devServer.static.directory of WebPack and correctly serve the zip file
    /* ... */
    proxy: {
      '/@mf-types.zip': {
        target: 'http://localhost:3000',
        changeOrigin: true,
        rewrite: () => `/@fs/${process.cwd()}/dist/@mf-types.zip`,
      },
    },
    fs: {
      /* ... */
      allow: ['./dist'],
      /* ... */
    },
  },
});

    }),
  ],
};

Webpack

// webpack.config.js
const { NativeFederationTypeScriptHost, NativeFederationTypeScriptRemote } = require('@module-federation/native-federation-typescript/webpack');
module.exports = {
  /* ... */
  plugins: [
    NativeFederationTypeScriptRemote({
      /* options */
    }),
    NativeFederationTypeScriptHost({
      /* options */
    }),
  ],
};

esbuild

// esbuild.config.js
import { build } from 'esbuild';
import { NativeFederationTypeScriptHost, NativeFederationTypeScriptRemote } from '@module-federation/native-federation-typescript/esbuild';

build({
  plugins: [
    NativeFederationTypeScriptRemote({
      /* options */
    }),
    NativeFederationTypeScriptHost({
      /* options */
    }),
  ],
});

Rspack

// rspack.config.js
const { NativeFederationTypeScriptHost, NativeFederationTypeScriptRemote } = require('@module-federation/native-federation-typescript/rspack');
module.exports = {
  /* ... */
  plugins: [
    NativeFederationTypeScriptRemote({
      /* options */
    }),
    NativeFederationTypeScriptHost({
      /* options */
    }),
  ],
};

Rolldown

// rolldown.config.js
import { NativeFederationTypeScriptHost, NativeFederationTypeScriptRemote } from '@module-federation/native-federation-typescript/rolldown';

export default {
  plugins: [
    NativeFederationTypeScriptRemote({
      /* options */
    }),
    NativeFederationTypeScriptHost({
      /* options */
    }),
  ],
};

TypeScript configuration

To have the type definitions automatically found for imports, add paths to the compilerOptions in the tsconfig.json:

{
  "paths": {
    "*": ["./@mf-types/*"]
  }
}
