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 learned about Angular services and how to correctly isolate the business rule from our applications in a simple and reusable way, as well as how Angular services use the singleton pattern for memory and performance optimization.

We worked with and studied Angular’s dependency injection mechanism and noticed how important it is to be able to organize and reuse services between components and other services. We also learned how to use the inject function for Angular services as an alternative to dependency injection via Angular’s constructor.

Finally, we worked with one of the main uses of services, communication with the backend, and in this chapter, we began to explore the integration of our frontend applications with the backend.

In the next chapter, we will study the best practices for using forms, the main way that our users enter information into our systems.
