Overview of this book

Angular is an open-source, front-end framework used to build web applications using TypeScript. Angular is a component-based framework, which means you build apps by developing and composing reusable components. This framework has all the built-in features needed to develop complex, feature-rich web apps. Written by an Angular specialist working with some of the top companies in the Netherlands, this book teaches you how to harness the full potential of the Angular framework. You’ll explore different front-end architecture designs and set up a scalable environment for Angular applications and libraries using Nx, before taking a deep dive into the framework's newest and most powerful features. Next, you’ll learn to manipulate the Document Object Model (DOM) with Angular directives, pipes, and animations, and build reusable components like a pro. The book spotlights best practices and flags potential pitfalls at every step of the way. You’ll also learn design patterns that fit well when using the Angular framework, reactive programming with RxJS and Angular signals, and how to manage application states effectively. The book teaches you about accessibility, testing, and optimizing your app for deployment. By the end of this book, you’ll be able to use Angular effectively to build enterprise-ready, scalable front-end applications.

Reactive programming using Angular Signals

We briefly discussed Angular Signals in Chapter 2, but let’s reiterate that and dive a bit deeper so that you can get a good grasp of Angular Signals and how they can help you handle code more reactively.

Angular Signals was introduced in Angular 16, and it’s one of the most significant changes for the framework since it went from AngularJS to Angular. With Signals, the Angular framework now has a reactive primitive in the Angular framework that allows you to declare, compute, mutate, and consume synchronous values reactively. A reactive primitive is an immutable value that alerts consumers when the primitive is set with a new value. Because all consumers are notified, the consumers can automatically track and react to changes in this reactive primitive.

Because Signals are reactive primitives, the Angular framework can better detect changes and optimize rendering, resulting in better performance. Signals are the first...
