The Reactive Extensions for JavaScript (RxJS 4) is a library for composing asynchronous and event-based programs using observable sequences, operators, and schedulers. This original Reactive-Extensions repository is legacy and has been superseded by the actively maintained reactivex/rxjs project.
Use cases
- compose async event streams in javascript
- handle ui events with observables
- debounce and combine ajax responses
- manage complex asynchronous data flows
- convert callbacks into observable streams
- learn reactive programming in javascript
When to choose
- maintaining a legacy codebase already using the rx 4.x package
- studying the original RxJS implementation and its operator set
- working in an environment pinned to the old rx npm package
When to avoid
- starting a new project - use the modern reactivex/rxjs (rxjs 7+) instead
- you need TypeScript support or current maintenance
- you need up-to-date documentation and community support
