1. Configure Routes:

Navigate to your project directory and open src/app/app-routing.module.ts. This file is where you define the routes for your application.

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

// Import components to be associated with routes
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
import { ContactComponent } from './contact/contact.component';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'about', component: AboutComponent },
  { path: 'contact', component: ContactComponent },
  // Add more routes as needed
];

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

2. Create Components:

ng generate component home
ng generate component about
ng generate component contact

This will create home.component, about.component, and contact.component along with their necessary files.

3. Add Router Outlet in App Component:

<h1>My App</h1>
<nav>
  <a routerLink="/">Home</a>
  <a routerLink="/about">About</a>
  <a routerLink="/contact">Contact</a>
</nav>
<router-outlet></router-outlet>
