Setting up Child (Nested) Routes in Angular

You can add many more outlets and routes, at the top level and in nested levels, creating a navigation tree with many branches. The router will generate the URL to go with it.

app.module.ts

import {BrowserModule} from '@angular/platform-browser';
import {NgModule} from '@angular/core';
import {FormsModule} from '@angular/forms';
import {HttpModule} from '@angular/http';

import {AppComponent} from './app.component';
import {HomeComponent} from './home/home.component';
import {UsersComponent} from './users/users.component';
import {ServersComponent} from './servers/servers.component';
import {UserComponent} from './users/user/user.component';
import {EditServerComponent} from './servers/edit-server/edit-server.component';
import {ServerComponent} from './servers/server/server.component';
import {ServersService} from './servers/servers.service';
import {RouterModule, Routes} from '@angular/router';

const appRoutes: Routes = [
  {path: '', component: HomeComponent},
  {
    path: 'users', component: UsersComponent, children: [
      {path: ':id/:name', component: UserComponent}]
  },
  {
    path: 'servers', component: ServersComponent, children: [
      {path: ':id', component: ServerComponent},
      {path: ':id/edit', component: EditServerComponent}
    ]
  },
];

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    UsersComponent,
    ServersComponent,
    UserComponent,
    EditServerComponent,
    ServerComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    RouterModule.forRoot(appRoutes)
  ],
  providers: [ServersService],
  bootstrap: [AppComponent]
})
export class AppModule {
}

users.component.html

<div class="row">
  <div class="col-xs-12 col-sm-4">
    <div class="list-group">
      <a
        [routerLink]="['/users',user.id,user.name]"
        href="#"
        class="list-group-item"
        *ngFor="let user of users">
        {{ user.name }}
      </a>
    </div>
  </div>
  <div class="col-xs-12 col-sm-4">
    <!--    <app-user></app-user>-->

        [fragment]="'loading'"
        href="#"
        class="list-group-item"
        *ngFor="let server of servers">
        {{ server.name }}
      </a>
    </div>
  </div>
  <div class="col-xs-12 col-sm-4">
    <router-outlet></router-outlet>
    <!--    <button class="btn btn-primary" (click)="onReload()">Reload Page</button>-->
