rxjs-patterns

What problem does it solve?

This Skill helps developers write robust, maintainable RxJS code within Angular applications by codifying established patterns and best practices used in the Nuclia frontend monorepo.

Core Features & Use Cases

• Operator Selection: Guides decisions on flattening (switchMap, concatMap, mergeMap) and combination (combineLatest, forkJoin, withLatestFrom) operators.
• State Management: Details correct usage of Subject, BehaviorSubject, and ReplaySubject for managing observable state.
• Error Handling & Cleanup: Enforces proper catchError placement and modern cleanup strategies like takeUntilDestroyed().
• Use Case: When implementing a new feature that involves fetching data based on user input, this Skill provides clear guidance on choosing the right operators to handle asynchronous operations efficiently and prevent common pitfalls like memory leaks or silent failures.
