I am a bit confused. What is the difference between these libraries?

https://github.com/ReactiveX/rxjs
https://github.com/Reactive-Extensions/RxJS

What is the differance between rx, @reactivex/rxjs rxjs on npm.

If you search npm there are multiple libraries for rxjs which one is the official?

https://www.npmjs.com/search?q=rx

RxJS 4 is hosted on: https://github.com/Reactive-Extensions/RxJS

RxJS 5 (https://github.com/ReactiveX/rxjs) replaces RxJS 4 and is relatively compatible with RxJS 4. README.md on gtihub says:

Reactive Extensions Library for JavaScript. This is a rewrite of Reactive-Extensions/RxJS and is intended to supersede it once this is ready.

RxJS 5 is completely written in TypeScript and compiled to both as ES6 and ES5 (as a bundle in UMD format).

There's also RxJS 6 currently in development.

Also, RxJS 4 is now called rx and npm while RxJS 5 is rxjs now. The scoped one @reactivex/rxjs is probably just an older npm package (they both come from the same repo).

    Note that they also changed some of the API in RxJS 5, so code written for RxJS 4 won't work with RxJS 5 without a migration effort. – Brandon Nov 08 '16 at 14:10
