RxJS: Reactive Extensions For JavaScript
The Roadmap from RxJS 7 to 8
Curious what's next for RxJS? Follow along with Issue 6367.
RxJS 7
FOR 6.X PLEASE GO TO THE 6.x BRANCH
Reactive Extensions Library for JavaScript. This is a rewrite of Reactive-Extensions/RxJS and is the latest production-ready version of RxJS. This rewrite is meant to have better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface.
Versions In This Repository
- master - This is all of the current work, which is against v7 of RxJS right now
- 6.x - This is the branch for version 6.X
Most PRs should be made to master.

Installation and Usage
ES6 via npm
1npm install rxjs
It's recommended to pull in the Observable creation methods you need directly from 'rxjs' as shown below with range.
If you're using RxJS version 7.2 or above, you can pull in any operator you need from the same spot, 'rxjs'.
1import { range, filter, map } from 'rxjs'; 2 3range(1, 200) 4 .pipe( 5 filter(x => x % 2 === 1), 6 map(x => x + x) 7 ) 8 .subscribe(x => console.log(x));
If you're using RxJS version below 7.2, you can pull in any operator you need from one spot, under 'rxjs/operators'.
1import { range } from 'rxjs'; 2import { filter, map } from 'rxjs/operators'; 3 4range(1, 200) 5 .pipe( 6 filter(x => x % 2 === 1), 7 map(x => x + x) 8 ) 9 .subscribe(x => console.log(x));
CDN
For CDN, you can use unpkg:
https://unpkg.com/rxjs@^7/dist/bundles/rxjs.umd.min.js
The global namespace for rxjs is rxjs:
1const { range } = rxjs; 2const { filter, map } = rxjs.operators; 3 4range(1, 200) 5 .pipe( 6 filter(x => x % 2 === 1), 7 map(x => x + x) 8 ) 9 .subscribe(x => console.log(x));
Goals
- Smaller overall bundles sizes
- Provide better performance than preceding versions of RxJS
- To model/follow the Observable Spec Proposal to the observable
- Provide more modular file structure in a variety of formats
- Provide more debuggable call stacks than preceding versions of RxJS
