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.

Summary

In this chapter, we explored the RxJS library and its basic elements, observables.

We learned what an observable is and how it differs from a promise or a function. With that knowledge, we refactored our project to handle data with the map operator, abstracting the implementation details of the component that will consume the service. We also learned about Angular’s async pipe and how it simplifies the management of subscription to an observable, leaving this task to the framework itself to manage.

Finally, we created a typeahead search field using RxJS to search for exercises based on the user’s typing event, using operators in order to optimize HTTP calls from our frontend. In the next chapter, we will explore the possibilities of the automated tests that we can do in our Angular application.
