reactive-programming
Implement reactive programming patterns using RxJS, streams, observables, and backpressure handling. Use when building event-driven UIs, handling async data streams, or managing complex data flows.
Why this skill is useful
Provides specific patterns and implementations for reactive programming with RxJS that the AI wouldn't reliably generate on its own.
What it needs
Requires rxjs installed locally. About 1k tokens when loaded. Last updated 2026-03-04. 307 stars on the source repository.
