1First you need to make component using 'ng generate'
2$ ng generate component home
3$ ng generate component about
4
5Next, in the src/app/app-routing.module.ts file import the components as follows:
6
7import { NgModule } from '@angular/core';
8import { Routes, RouterModule } from '@angular/router';
9
10import { HomeComponent } from './home/home.component';
11import { AboutComponent } from './about/about.component';
12Next, add the routes as follows:
13
14const routes: Routes = [
15  { path: 'home', component: HomeComponent },
16  { path: 'about', component: AboutComponent }
17
18];
19So now if you visit the /home path you should go to home component and if you visit the /about path you should go to the about component.
