Angular微前端中所有远程应用是否需处于同一Angular工作区？

完全可以。借助Angular模块联邦（Module Federation），你完全可以将分属不同代码仓库、不同工作区的Angular应用作为远程应用，加载到同一个壳应用中。只要远程应用能通过网络对外暴露其remoteEntry.js入口文件，壳应用就能完成加载集成。

以下是完整的配置示例：

壳应用配置 #

1. webpack.config.js #

const { shareAll, withModuleFederationPlugin } = require('@angular-architects/module-federation/webpack');

module.exports = withModuleFederationPlugin({

  remotes: {
    "appOne": "http://localhost:4201/remoteEntry.js",    
    "appTwo": "http://localhost:4202/remoteEntry.js",    
  },

  shared: {
    ...shareAll({ singleton: true, strictVersion: true, requiredVersion: 'auto' }),
  },

});

2. main.ts #

import { loadRemoteEntry } from '@angular-architects/module-federation';

import('./bootstrap')
    .catch(err => console.error(err));

Promise.all([
    loadRemoteEntry('http://localhost:4201', 'appOne'),
    loadRemoteEntry('http://localhost:4202', 'appTwo'),
])
    .catch((err) => console.error('Error loading remote entries', err))
    .then(() => import('./bootstrap'))
    .catch((err) => console.error(err));    

3. app-routing.module.ts（仅路由部分） #

export const APP_ROUTES: Routes = [
  {
    path: '',
    component: HomeComponent,
    pathMatch: 'full'
  },
  {
    path: 'app-one',
    loadChildren: () => loadRemoteModule({
                            remoteName: 'appOne',
                            exposedModule: './appOne',
                        }).then((m) => m.AppOneModule)
  },
  {
    path: 'app-two',
    loadChildren: () => loadRemoteModule({
                            remoteName: 'appTwo',
                            exposedModule: './appTwo',
                        }).then((m) => m.AppTwoModule)
  }
];

远程应用One配置 #

1. webpack.config.js #

const { shareAll, withModuleFederationPlugin } = require('@angular-architects/module-federation/webpack');

module.exports = withModuleFederationPlugin({

  name: 'appOne',

  exposes: {
    './appOne': './projects/app-one/src/app/app-one/app-one.module.ts',
  },

  shared: {
    ...shareAll({ singleton: true, strictVersion: true, requiredVersion: 'auto' }),
  },

});

2. app-one.module.ts #

import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';

import { AppOneComponent } from './app-one.component';
import { AppOneRoutingModule } from './app-one-routing-module';

@NgModule({
    declarations: [AppOneComponent],
    imports: [CommonModule, AppOneRoutingModule]
})
export class AppOneModule {}

3. app-one-routing-module.ts #

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { AppOneComponent } from './app-one.component';

const routes: Routes = [{ path: '', component: AppOneComponent }];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule],
})
export class AppOneRoutingModule {}
