1. 项目结构

microfrontend-demo/
├── shell/                # 主应用 (Shell)
├── mfe1/                 # 微前端应用1
├── mfe2/                 # 微前端应用2
└── shared/               # 共享库

2. 主应用 (Shell) 配置

shell/webpack.config.js

const ModuleFederationPlugin = require("webpack/lib/container/ModuleFederationPlugin");
const mf = require("@angular-architects/module-federation/webpack");
const path = require("path");module.exports = {output: {uniqueName: "shell",publicPath: "auto"},optimization: {runtimeChunk: false},plugins: [new ModuleFederationPlugin({remotes: {"mfe1": "mfe1@http://localhost:4201/remoteEntry.js","mfe2": "mfe2@http://localhost:4202/remoteEntry.js"},shared: {"@angular/core": { singleton: true, strictVersion: true },"@angular/common": { singleton: true, strictVersion: true },"@angular/router": { singleton: true, strictVersion: true },"@angular/common/http": { singleton: true, strictVersion: true },// 其他共享库...}})]
};

shell/src/app/app-routing.module.ts

使用：RouterModule.forRoot(routes)

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';const routes: Routes = [{path: '',pathMatch: 'full',redirectTo: 'home'},{path: 'home',loadChildren: () => import('./home/home.module').then(m => m.HomeModule)},{path: 'mfe1',loadChildren: () => import('mfe1/Module').then(m => m.Mfe1Module)},{path: 'mfe2',loadChildren: () => import('mfe2/Module').then(m => m.Mfe2Module)},{path: '**',redirectTo: 'home'}
];@NgModule({imports: [RouterModule.forRoot(routes)],exports: [RouterModule]
})
export class AppRoutingModule { }

shell/src/app/app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { RouterModule } from '@angular/router';@NgModule({declarations: [AppComponent],imports: [BrowserModule,RouterModule,AppRoutingModule],providers: [],bootstrap: [AppComponent]
})
export class AppModule { }

3. 微前端应用1 (MFE1) 配置

mfe1/webpack.config.js

只需导出包含所有路由配置的Module即可

const ModuleFederationPlugin = require("webpack/lib/container/ModuleFederationPlugin");
const mf = require("@angular-architects/module-federation/webpack");
const path = require("path");module.exports = {output: {uniqueName: "mfe1",publicPath: "auto"},optimization: {runtimeChunk: false},plugins: [new ModuleFederationPlugin({name: "mfe1",filename: "remoteEntry.js",exposes: {'./Module': './src/app/mfe1/mfe1.module.ts',},shared: {"@angular/core": { singleton: true, strictVersion: true },"@angular/common": { singleton: true, strictVersion: true },"@angular/router": { singleton: true, strictVersion: true },// 其他共享库...}})]
};

mfe1/src/app/mfe1/mfe1.module.ts

使用 RouterModule.forChild(routes) 时，若未将所有路由配置集中在一个模块中，则需在每个组件内单独添加 RouterModule.forChild([{path:'',component:''}]) 配置。

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { Mfe1Component } from './mfe1.component';const routes: Routes = [{ path: '', component: Mfe1Component },{ path: 'details', loadChildren: () => import('./details/details.module').then(m => m.DetailsModule) }
];@NgModule({declarations: [Mfe1Component],imports: [CommonModule,RouterModule.forChild(routes)]
})
export class Mfe1Module { }

4. 微前端应用2 (MFE2) 配置

mfe2/webpack.config.js

只需导出包含所有路由配置的Module即可

const ModuleFederationPlugin = require("webpack/lib/container/ModuleFederationPlugin");
const mf = require("@angular-architects/module-federation/webpack");
const path = require("path");module.exports = {output: {uniqueName: "mfe2",publicPath: "auto"},optimization: {runtimeChunk: false},plugins: [new ModuleFederationPlugin({name: "mfe2",filename: "remoteEntry.js",exposes: {'./Module': './src/app/mfe2/mfe2.module.ts',},shared: {"@angular/core": { singleton: true, strictVersion: true },"@angular/common": { singleton: true, strictVersion: true },"@angular/router": { singleton: true, strictVersion: true },// 其他共享库...}})]
};

mfe2/src/app/mfe2/mfe2.module.ts

使用 RouterModule.forChild(routes) 时，若未将所有路由配置集中在一个模块中，则需在每个组件内单独添加 RouterModule.forChild([{path:'',component:''}]) 配置。

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { Mfe2Component } from './mfe2.component';const routes: Routes = [{ path: '', component: Mfe2Component },{ path: 'settings', loadChildren: () => import('./settings/settings.module').then(m => m.SettingsModule) }
];@NgModule({declarations: [Mfe2Component],imports: [CommonModule,RouterModule.forChild(routes)]
})
export class Mfe2Module { }

5. 共享库配置

shared/package.json

{"name": "shared","version": "1.0.0","peerDependencies": {"@angular/core": "^15.0.0","@angular/common": "^15.0.0","@angular/router": "^15.0.0"}
}

6. 导航组件示例

shell/src/app/nav/nav.component.ts

import { Component } from '@angular/core';
import { Router } from '@angular/router';@Component({selector: 'app-nav',template: `<nav><button (click)="navigateTo('home')">Home</button><button (click)="navigateTo('mfe1')">MFE1</button><button (click)="navigateTo('mfe2')">MFE2</button></nav>`
})
export class NavComponent {constructor(private router: Router) {}navigateTo(route: string): void {this.router.navigate([route]);}
}

7. 环境配置

shell/src/environments/environment.ts

export const environment = {production: false,mfe1Url: 'http://localhost:4201/remoteEntry.js',mfe2Url: 'http://localhost:4202/remoteEntry.js'
};

8. 启动脚本

在 package.json 中添加并行启动脚本：

"scripts": {"start": "npm-run-all --parallel start:shell start:mfe1 start:mfe2","start:shell": "ng serve shell -o --port 4200","start:mfe1": "ng serve mfe1 -o --port 4201","start:mfe2": "ng serve mfe2 -o --port 4202"
}
