FOR V 5.X PLEASE GO TO THE 5.0 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

To import only what you need by patching (this is useful for size-sensitive bundling):

import { Observable, Subject, ReplaySubject, from, of, range } from 'rxjs';
import { map, filter, switchMap } from 'rxjs/operators';

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

Alternatively, you can use the built-in pipe method on Observables. See pipeable operators for more information.
