Angular signals manage component state by creating writable values with signal(), deriving synchronous state with computed(), and handling side effects using effect(). This provides a predictable reactivity model for Angular v20+ applications.

The best way to convert an RxJS Observable to an Angular signal is using the toSignal() interop function. This facilitates a shift from Observable-centric patterns to a more performant, synchronous reactivity model for asynchronous data flows.

Yes, you can use Angular signals for service-level data management. Signal-based reactive state management addresses challenges in managing both component state and service-level data efficiently within the Angular framework.

Computed signals in Angular work by defining derived values that automatically update when their dependencies change. The computed() function creates synchronous reactive state that tracks writable signals without manual subscription management.

You should replace complex RxJS-based state management with signals to improve performance and readability. Signals use a synchronous reactivity model, but RxJS interop functions like toObservable() maintain compatibility for existing asynchronous operations.

Use the effect() function in Angular signal state management when you need to handle side effects or asynchronous operations. It automatically tracks signal dependencies and executes logic when those signal values change.
