Overview of this book

Single page applications (SPAs) have become the standard for most web experiences. Angular, with its batteries-included approach, has emerged as a powerful framework for simplifying the development of these interfaces by offering a comprehensive toolbox. This book guides you through the Angular ecosystem, uncovering invaluable design patterns and harnessing its essential features. The book begins by laying a strong foundation, helping you understand when and why Angular should be your web development framework of choice. The next set of chapters will help you gain expertise in component design and architecting efficient, flexible, and high-performing communication patterns between components. You’ll then delve into Angular's advanced features to create forms in a productive and secure way with robust data model typing. You'll also learn how to enhance productivity using interceptors to reuse code for common functionalities, such as token management, across various apps. The book also covers micro frontend architecture in depth to effectively apply this architectural approach and concludes by helping you master the art of crafting tests and handling errors effortlessly. By the end of this book, you'll have unlocked the full potential of the Angular framework.

Optimizing the experience – Resolve

Performance is one of the biggest variables that impact the experience and satisfaction of our users; therefore, optimal performance should be a constant goal for the web developer.

Perceived perception is the game we want to win, and we have plenty of options in the Angular ecosystem. We can load the information that our page will require before it renders and, for that, we will use the Resolveroute saver resource.

Unlike the guard we studied earlier, its purpose is to return information needed by the page being directed by the route.

We will create this guard using the Angular CLI. In your command prompt, use the following command:

ng g resolver diary/diary

In the new file created, let’s change the function that the Angular CLI generated:

export const diaryResolver: ResolveFn<ExerciseSetListAPI> = (route, state) => {
  const exerciseSetsService = inject(ExerciseSetsService);
  return exerciseSetsService...
