Angular 9使用动态路由动态导入模块

// app.routing.ts

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

const routes: Routes = [
  { path: 'lazy', loadChildren: () => import('./lazy/lazy.module').then(m => m.LazyModule) }
];

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

// app.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `
    <h1>Angular Dynamic Routing Example</h1>
    <nav>
      <a routerLink="/lazy">Lazy Module</a>
    </nav>
    <router-outlet></router-outlet>
  `
})
export class AppComponent { }

// lazy.module.ts

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

import { LazyComponent } from './lazy.component';

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

@NgModule({
  declarations: [LazyComponent],
  imports: [
    CommonModule,
    RouterModule.forChild(routes)
  ]
})
export class LazyModule { }

// lazy.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-lazy',
  template: '<h2>Lazy Component</h2>'
})
export class LazyComponent { }
