RouterOutlet

A RouterOutlet is a placeholder that Angular dynamically fills based on the application's route. The component for the route being activated is created & inserted next to the <router-outlet></router-outlet> element. In order to make use of the RouterOutlet we must give component access to the router components by passing ROUTER_DIRECTIVES in the component directives array.

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

@Component({
  selector: 'app',
  directives: [ROUTER_DIRECTIVES],
  template: `
    <nav>
      <a [routerLink]="['/component-one']">Component One</a>
      <a [routerLink]="['/component-two']">Component Two</a>
    </nav>
    <router-outlet></router-outlet>
    <!-- Route components are added by router here -->
  `
})
export class AppComponent {}

In the above example, the component corresponding to the route specified will be placed after the <router-outlet></router-outlet> element when the link is clicked.
