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 simple.css o pico.css

Para este ejemplo usaremos pico.css

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">
  <h1>Angular Testing</h1>
  <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">
  <h1>Products Component</h1>
</section>

preview.component.html
