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:

`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:

`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:

`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:

`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

`js
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

`vue

`
