rxjs-development

name: rxjs-development description: Use this skill whenever work requires RxJS. Covers built-in-operator preference, the $ suffix, private subjects exposed via asObservable(), error handling/logging within the chain, flat composition (no nested subscriptions), and combineLatestWith.

RxJS Development Skill

Rules

• ALWAYS use built-in rxjs utilities when available instead of creating a custom one.
• ALWAYS suffix RxJS observerable variables with $.
• ALWAYS create subjects as private implementation details and only expose publicly what is needed

// MUST DO
private _focusRequestSubject = new Subject<void>();
// ...
public focusRequest$ = this._focusRequestSubject.asObservable();

• ALWAYS make sure error handling is done somewhere in the chain of events (if error handling is done higher up, lower usage error handling is optional).
• ALWAYS make sure streams properly composed to avoid nested subscriptions whenever possible.
• ALWAYS log error in catchError() using the logManager.warn() or logManager.error().
• ONLY use combineLatestWith to combine multiple streams.
• NEVER expose a subject directly as public.
