Prevent memory leaks in Angular Observables by using the async pipe for automatic subscription management, or apply the takeUntil operator to explicitly clean up subscriptions during component destruction.

Manage centralized state by storing data in a private BehaviorSubject, exposing it as a read-only Observable to components, and updating the state immutably to avoid unintended mutations and ensure consistent data flow.

Cache HTTP requests in Angular by applying the shareReplay operator to the observable returned by HttpClient, which multicasts the response and prevents duplicate network calls for subsequent subscribers.

Yes, the reactive programming patterns provided are fully compatible with Angular 21 and current RxJS semantics, ensuring safe state sharing and effective observable-based state management.

Exposing an Observable instead of a BehaviorSubject restricts components from directly mutating the centralized state, enforcing immutability and ensuring the service retains exclusive control over state updates.

Convert the API by keeping the BehaviorSubject private and exposing its value through a public asObservable method, then update consuming components to read the data using the async pipe.
