angular-signals

Angular signals provide a fine-grained, synchronous reactivity model that replaces verbose Observables. You create writable state with signal(), derive values with computed(), and compose dependent state with linkedSignal() for simpler state management across components and services.

To bridge signals and RxJS Observables, use toSignal and toObservable functions. This enables seamless RxJS interoperability, allowing you to integrate signal-based state management with existing reactive streams across your components and stores.

Use the effect() function to run code in response to Angular signal state changes. Effects execute automatically when dependent signals update and support automatic cleanup, making them ideal for synchronizing state with external systems.

Yes, signal-based state management primitives require Angular v20 or later. This version requirement ensures you have access to the full suite of core APIs, including signal, computed, linkedSignal, and effect for safe reactive patterns.

Yes, you can build form and state stores using Angular signals. By combining writable signals with computed values and linkedSignal, you can create resource-like patterns and manage complex dependent state across your application.
