RxJS is a reactive programming library for composing asynchronous and event-based programs using Observables. This repository hosts the next-generation RxJS 9, which leverages the native web-platform Observable with a conforming fallback.

Use cases

  • compose async event streams in JavaScript
  • handle user input events reactively
  • manage complex async data flows in Angular apps
  • debounce and throttle event handling
  • cancel and retry async operations declaratively

When to choose

  • you need composable, cancellable async/event pipelines
  • you're building Angular apps where RxJS is idiomatic
  • you want a mature, battle-tested reactive library with a huge ecosystem

When to avoid

  • your app has only simple promise-based async flows
  • you want minimal bundle size and no learning curve
  • your team is unfamiliar with reactive programming concepts
