Overview of this book

Angular has long been the framework of choice for web development projects of various scales, offering much-needed stability and a rich tooling ecosystem for building production-ready web and mobile apps. This recipe-based guide ensures high performance apps with the latest version of Angular, helping you to build up your Angular expertise with a wide range of recipes across key tasks in web development. In this second edition, the recipes have been updated, added, and improved based on developer feedback, new challenges, and Angular 17. The first few chapters will show you how to utilize core Angular concepts such as components, directives, and services to get you ready for building frontend web apps. You’ll then develop web components with Angular and go on to learn about advanced concepts such as dynamic components loading and state management with NgRx for achieving real-time performance. Later chapters will focus on recipes for effectively testing your Angular apps to make them fail-safe, before progressing to techniques for optimizing your app’s performance. Finally, you’ll create Progressive Web Apps (PWA) with Angular to provide an intuitive experience for users. By the end of this book, you’ll be able to create full-fledged, professional-looking Angular apps and have the skills you need for frontend development.

Detaching the change detector from components

In the previous recipe, we learned how to use the OnPush strategy in our components to avoid Angular change detection running unless one of the @Input() bindings has changed. There is, however, another way to tell Angular to not run change detection at all for a particular component and its subtree. This cuts the component and its subtree from the change detection cycle completely, as shown in Figure 12.5, which can result in an increase in the overall performance. This is also handy when you want full control of when to run change detection. In this recipe, you’ll learn how to completely detach the change detector from an Angular component to gain performance improvements.
