angular-signals

Angular signals replace Observable boilerplate with fine-grained reactivity for simpler state management. You can use signal for writable state, computed for derived state, and effect for side effects.

Derived state in Angular is created using the computed function. It automatically tracks dependent signals and updates only when those specific dependencies change, ensuring efficient fine-grained reactivity.

Yes, Angular signals support RxJS interoperability. This allows you to integrate signal-based reactivity with existing Observable streams and practical Angular usage patterns within your application.

Dependent state in Angular signals is handled using linkedSignal. This provides a structured way to manage state that relies on other signals, alongside using effect for triggering side effects when values change.

Yes, you need Angular v20 or higher to use this signals approach. It requires access to the @angular/core signals API to implement writable, derived, and dependent state management effectively.
