Mastering Reactivity with Angular Signals

Modern web applications thrive on reactivity, where data changes automatically, thereby triggering updates in the UI. Angular Signals, introduced in version 17, streamlines this process by offering a powerful and concise way to manage reactive data within your Angular applications.

This chapter delves into the core concepts, API functionalities, advantages, and relationship of Signals with RxJS. We will also see how we can improve the reactivity of our Recipe app further using Angular Signals.

So, in this chapter, we’re going to cover the following main topics:

• Understanding the motivation behind Signals
• Unveiling the Signal API
• Unlocking the Power of RxJS and Angular Signals
• Integrating Signals into our recipe app
• Reactive data binding with Signals
