Getting Started with Angular Signals

What are Angular Signals?

Angular Signals are a new reactive primitive introduced to simplify state management. They provide a way to define reactive values and their dependencies, making it easier to build performant Angular applications.

Why Use Signals?

Signals offer several advantages over traditional approaches. They are synchronous, fine-grained, and deeply integrated into Angular's change detection system, enabling OnPush-like performance without the complexity.

Basic Usage

Creating a signal is straightforward. Use the signal() function to define a reactive value, and computed() to derive state from other signals. The framework automatically tracks dependencies and updates the UI when signal values change.

Getting Started

To start using signals in your Angular application, ensure you are on Angular 17 or later. Signals are stable and production-ready, providing a solid foundation for building reactive user interfaces.
