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.

Handling User Inputs: Forms

Since the early days of web applications, before the concept of Single Page Applications (SPAs), in HTML 2, the <form> tag has been used to create, organize, and send forms to the backend.

In common applications, such as banking systems and health applications, we use forms to organize the inputs that our users need to perform in our systems. With such a common element in web applications, it is natural that Angular, a framework whose philosophy is batteries included, offers this feature to its developers.

In this chapter, we will delve into the following forms features in Angular:

  • Template-driven forms
  • Reactive forms
  • Data validation
  • Custom validations
  • Typed reactive forms

By the end of this chapter, you will be able to create maintainable and fluid forms for your user, in addition to improving your productivity with this type of task.
