(精华2020年6月14日更新)Angular实战篇 路由懒加载

子模块 article-routing.module

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import {ArticleComponent} from './article.component';
import {ArticlelistComponent} from './components/articlelist/articlelist.component';
import { from } from 'rxjs';

const routes: Routes = [
  {
    path:'',
    component:ArticleComponent
  },
  {
    path:'list',
    component:ArticlelistComponent
  }

];

// forChild ：用在子模块加载路由配置
@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class ArticleRoutingModule { }

子模块

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ArticleRoutingModule } from './article-routing.module';
import { ArticleComponent } from './article.component';
import { ArticlelistComponent } from './components/articlelist/articlelist.component';
import { InfoComponent } from './components/info/info.component';

import {FormsModule} from '@angular/forms';

@NgModule({
  declarations: [ArticleComponent, ArticlelistComponent, InfoComponent],
  imports: [
    CommonModule,
    ArticleRoutingModule,
    FormsModule
  ]
})
export class ArticleModule { }

根模块

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


const routes: Routes = [
   {
    path:'article',
    // loadChildren:'./module/article/article.module#ArticleModule' // 方式一
    //方式二  
    loadChildren: () => import('./module/article/article.module').then( m => m.ArticleModule) 
   },
   {
    path:'user',
    loadChildren: () => import('./module/user/user.module').then( m => m.UserModule)

    loadChildren: () => import('./module/product/product.module').then( m => m.ProductModule) 
   },{
     path:'**',
     redirectTo:'article'
   }
];

// forRoot 用在根模块加载路由配置
@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

根模块

import { BrowserModule } from '@angular/platform-browser';
