Teams using angular-rxjs-interop should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# RxJS Interop
## **Priority: P1 (HIGH)**
## Principles
- **Async to Sync**: Use **toSignal(observable$, { initialValue: defaultValue })** from **@angular/core/rxjs-interop** to convert Observables (HTTP, Events) to Signals for template rendering. Call in an **injection context** (class field or constructor). **toSignal auto-unsubscribes** on component destroy. Provide **initialValue** to avoid `undefined`.
- **Sync to Async**: Use **toObservable(this.query)** when you need RxJS operators (**debounceTime**, **switchMap**, **distinctUntilChanged**) on a Signal. Then wrap back with **toSignal()** if rendering.
- **Auto-Unsubscribe**: `toSignal` automatically unsubscribes.
- **Cleanup**: Use **takeUntilDestroyed()** for manual subscriptions in **injection contexts**. For use outside, **inject(DestroyRef)** and call `takeUntilDestroyed(destroyRef)`.
## Guidelines
- **HTTP Requests**:
- GET: `http.get<User[]>(...).pipe(catchError(() => of([])))` -> `toSignal(..., { initialValue: [] })`. Use in templates as **{{ users() }}**.
- Consider **httpResource()** for simpler reactive HTTP in newer versions.
- POST/PUT: Trigger explicit subscribe() or lastValueFrom().
- **Race Conditions**: Handle async loading states. `toSignal` requires an `initialValue` or handles `undefined`.
## Anti-Patterns
- **No manual subscribe in templates**: Use `toSignal()` for Observables rendered in templates.
- **No BehaviorSubject for state**: Replace with `signal()` + `toObservable()` for RxJS interop.
- **No global takeUntil**: Use `takeUntilDestroyed()` scoped to the injection context. **Never use a global Subject** with takeUntil — it leaks if Subject is never completed.
