RxJS

• Use RxJS for asynchronous streams, events and complex reactive flows.
• Do not use RxJS when simple synchronous signals are sufficient.
• Prefer declarative observable pipelines.
• Avoid nested subscribe.
• Avoid manual subscriptions where async, signals or framework helpers are sufficient.
• Prefer takeUntilDestroyed or equivalent Angular lifecycle integration for manual subscriptions.
• Always consider subscription lifetime.
• Avoid memory leaks from unmanaged subscriptions.
• Use the correct flattening operator for the required semantics.
• Do not use switchMap, mergeMap, concatMap or exhaustMap interchangeably.
• Avoid unnecessary Subject usage.
• Prefer exposing observables instead of exposing mutable subjects.
• Prefer BehaviorSubject only when a current value is actually required.
• Avoid excessive observable chains for simple state.
• Avoid converting repeatedly between signals and observables without need.
