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.

Exploring Reactivity with RxJS

In a web application, one of the most challenging tasks is dealing with the asynchronous nature of the web. An application cannot predict when events such as requests to the backend, changing routes, and simple user interactions will happen. Imperative programming in these cases is more complex and susceptible to errors.

The RxJS library that makes up the Angular ecosystem aims to make controlling asynchronous flows simpler using declarative and reactive programming.

In this chapter, we will cover the following topics:

  • Observables and operators
  • Handling data – transformation operators
  • Another way to subscribe – the async pipe
  • Connecting information flows – high-order operators
  • Optimizing data consumption – filter operators
  • How to choose the correct operator

By the end of the chapter, you will be able to create better experiences for your users by integrating their actions with backend...
