Lo primero antes de hacer pruebas a las conexiones http con conexiones a API's sera crear nuestro setup.

Para ello lo primero sera instalar un framework minimalista de diseño que tenga precargado las etiquetas html pero que no sea tan pesado. Por lo que no se tendra que pensar en clases como por ejemplo miligram o o

Para este ejemplo usaremos

lo instalamos

npm install @picocss/pico

una vez instalado vamos al nodemodules, buscamos la carpeta de @picocss/pico/css y buscamos el archivo pico.min.css, damos clic derecho y copiamos su ruta relativa.

despues vamos al archivo angular.json y lo pegamos en la reglas styles

"options": {
            "styles": [
              "src/styles.scss",
              "node_modules/@picocss/pico/css/pico.min.css"
            ],
            "scripts": []
          },

con estos cambios vamos a reescribir la landing page de nuestra aplicación

app.component.html

<header class="container">
  <h2>Angular Testing</h2>
  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Beatae illum saepe odio suscipit id sapiente consequuntur, ipsa laboriosam eius debitis quidem nisi quos veritatis eum soluta adipisci repellat commodi. Esse.</p>
  <nav>
    <ul>
      <li><a href="/">Home</a></li>
      <li><a routerLink="/products">Products</a></li>
      <li><a routerLink="/pico-preview">Pico Preview</a></li>
    </ul>
  </nav>
</header>
<router-outlet></router-outlet>

posteriormente creamos la carpeta components con dos componentes el de produts y el de pico-preview

ng g c components/products

ng g c components/pico-preview

y vamos a hacer un routing a estos componentes para verlos renderizados

app-routing.module.ts

import { ProductsComponent } from './components/products/products.component';
import { PicoPreviewComponent } from './components/pico-preview/pico-preview.component';

const routes: Routes = [
  {
    path: 'products',
    component: ProductsComponent
  },
  {
    path: 'pico-preview',
    component: PicoPreviewComponent
  }
];

luego modelamos los componentes de products y preview

products.component.html

<section class="container">
  <h2>Products Component</h2>
</section>

preview.component.html

<!-- preview -->

Muy buen aporte!

No olviden llamar RouterLink en el app.components.ts para que les funcione router link del html:

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterOutlet, RouterLink } from '@angular/router';

import { Calculator } from './calculator'

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [CommonModule, RouterOutlet, RouterLink ],
  templateUrl: './app.component.html',
  styleUrl: './app.component.scss'
})
export class AppComponent {
  title = 'ng-testing-services';

  ngOnInit() {
    const calculator = new Calculator();
    const rta = calculator.multiply(1,4);
    
  }
}

Para los que están usando Angular 17, donde existe el archivo app.routes.ts y es en este donde se declaran las rutas; pero no les funciona los enlaces cuando dan click ya sea en "products" o "pico-preview". Deben también importar en el app.component.ts (o en el componente correspondiente) la clase RouterLink para poner a funcionar la navegación entre los componentes.

Si tienen problema instalando PicoCSS pueden probar instalandolo por CDN en vez de npm, solo es colocar esta línea en el <head> del archivo index.html

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@picocss/pico@1/css/pico.min.css">

Hola, tengo problemas para usar los estilos de picocss. Agregué la ruta en angular.json como se muestra en la imagen, le pongo clase container, incluso copié y pegué el app html. Viendo el angular.json del git, no tiene la ruta de picocss.

no puedo agregarle los estilos de css de pico, simplemente no me los toma, ya lo compilé varias veces y nada

El profesor debe tener mucho conocimiento y no dudo mucho del esfuerzo que hará por enseñarnos, pero un tips, algunos detalles pareceran pequeños pero a veces te hacen ir a leerte para que funciona y para que lo esta utilizando el profesor, digo yo que considerando que uno esta pagando podrian ser mas especificos y que no se salgan esos detalles.
