Introduction
Reactive UIs are essential for modern web applications, ensuring seamless and efficient updates when data changes. Traditionally, RxJS Observables have been used for reactivity in Angular. However, with the introduction of Angular Signals, building reactive UIs has become simpler, more intuitive, and performance-friendly. In this article, we’ll explore how to leverage Angular Signals to build a reactive UI.
What are Angular Signals?
Angular Signals are a new reactive state management mechanism introduced to simplify state handling. Unlike RxJS, which follows a push-based model, Signals work on a pull-based model, meaning they update only when accessed, leading to better performance and fewer unnecessary computations.
Key Features of Angular Signals:
- Simplifies state management without requiring subscriptions
- Pull-based reactivity (updates only when read)
- Automatic dependency tracking
- No need to manually unsubscribe
Setting Up Angular Signals
To start using Signals, First ensure you are using an Angular version that supports them.
