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.

The first module – AppModule

The modules in Angular are so important to the framework that when you start a project, it automatically creates a module called AppModule.

This module contains all the parameters we studied in the previous section (declarations, providers, imports, and exports), plus one additional parameter: bootstrap. This module contains the first component to be injected into the application’s index.html file and will be the root of your Angular application’s component tree.

You may be wondering which index.html file and which tree this is.

As we described in Chapter 1, Starting Projects the Right Way, Angular is a framework for single-page applications (SPAs), and the index.html file is in fact the only page delivered by the web server to its user.

All interfaces rendered by the Angular engine (called Ivy) are built from this index.html file and the first component is described in the bootstrap metadata. This rendering obeys a data...
