RxJS 7 (beta)

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.

Installation and Usage

ES6 via npm

npm install rxjs

It's recommended to pull in the Observable creation methods you need directly from

'rxjs'
as shown below with
range
. And you can pull in any operator you need from one spot, under
'rxjs/operators'
.
import { range } from "rxjs";
import { map, filter } from "rxjs/operators";

range(1, 200) .pipe( filter(x => x % 2 === 1), map(x => x + x) ) .subscribe(x => console.log(x));

CDN

For CDN, you can use unpkg:

https://unpkg.com/rxjs/bundles/rxjs.umd.min.js

The global namespace for rxjs is

rxjs
:
const { range } = rxjs;
const { map, filter } = rxjs.operators;

range(1, 200) .pipe( filter(x => x % 2 === 1), map(x => x + x) ) .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

Building/Testing

  • npm run compile
    build everything
  • npm test
    run tests
  • npm run dtslint
    run dtslint tests
