httpResource in Angular
Angular interview exercise on HttpClient, difficulty 2 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
PostsComponent pages through GET /api/posts?page=N (an array of titles) with httpResource and a `page` signal starting at 1. Show <p class="loading">Loading…</p> while loading, the titles as <li> once loaded, <p class="error">Could not load page N</p> on an error, and a <button class="next"> that moves to the next page.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Progress is saved in your browser, and in your account if you sign in.
