You can replace BehaviorSubject with Angular signals by using the writable signal() API for synchronous state management. This reduces boilerplate and provides a lightweight approach to handling reactive component state.

The computed() function creates derived state that automatically updates when its dependencies change. linkedSignal() manages dependent state, allowing you to link signals together for more complex reactive state scenarios across your application.

You trigger side effects in Angular signals by using the effect() API. This allows you to execute synchronous logic whenever the value of a dependent signal changes, replacing traditional Observable subscription side effects.

Yes, signal-based state management using built-in APIs like signal(), computed(), linkedSignal(), and effect() requires Angular v20+. These APIs are imported directly from @angular/core to manage reactive state.

Yes, Angular signals support RxJS interop via the optional toSignal and toObservable functions. This allows you to bridge traditional Observable workflows with the new synchronous signal-based state management approach.

The best way to create derived state without manual subscriptions is using the computed() function from Angular signals. It automatically tracks dependencies and recalculates synchronously whenever an underlying writable signal changes.
