A Vite/Rollup plugin which support Module Federation. Inspired by Webpack and compatible with Webpack Module Federation.

Install

npm install @originjs/vite-plugin-federation --save-dev

or

yarn add @originjs/vite-plugin-federation --dev

Usage

Using the Module Federation usually requires more than 2 projects, one as the host side and one as the remote side.

Step 1: Configure the remote side.

• for a vite project, modify vite.config.js:

// vite.config.js
import federation from "@originjs/vite-plugin-federation";
export default {
    plugins: [
        federation({
            name: 'remote-app',
            filename: 'remoteEntry.js',
            // Modules to expose
            exposes: {
                './Button': './src/Button.vue',
            },
            shared: ['vue']
        })
    ]
}

• for a rollup project, modify rollup.config.js:

// rollup.config.js
import federation from '@originjs/vite-plugin-federation'
export default {
    input: 'src/index.js',
    plugins: [
        federation({
            name: 'remote-app',
            filename: 'remoteEntry.js',
            // Modules to expose
            exposes: {
                './Button': './src/button'.
            },
            shared: ['vue']
        })
    ]
}

Step 2: Configure the host side

• for a vite project, modify vite.config.js:

// vite.config.js
import federation from "@originjs/vite-plugin-federation";
export default {
    plugins: [
        federation({
            name: 'host-app',
            remotes: {
                remote_app: "http://localhost:5001/assets/remoteEntry.js",
            },
            shared: ['vue']
        })
    ]
}

• for a rollup project, modify rollup.config.js:

// rollup.config.js
import federation from '@originjs/vite-plugin-federation'
export default {
    input: 'src/index.js',
    plugins: [
        federation({
            name: 'host-app',
            remotes: {
                remote_app: "http://localhost:5001/remoteEntry.js",
            },
            shared: ['vue']
        })
    ]
}

Step 3: Using remote modules on the host side

Using a Vue project as an example

import { createApp, defineAsyncComponent } from "vue";
const app = createApp(Layout);
...
const RemoteButton = defineAsyncComponent(() => import("remote_app/Button"));
app.component("RemoteButton", RemoteButton);
app.mount("#root");

Using remote components in templates

<template>
    <div>
        <RemoteButton />
    </div>
</template>
