any-observable

Support any Observable library and polyfill

Like any-promise. (Docs are lacking here, so refer to those docs for now)

Install

$ npm install any-observable

You must also install the Observable library you want:

$ npm install zen-observable

Usage

const Observable = require('any-observable'); // Using `zen-observable` since it's installed
 
Observable.of(1, 2).forEach(value => {
    console.log(value);
});
//=> 1
//=> 2

Registration Shortcuts

This adds the following shortcut registrations:

• rxjs-min: Bare bones RxJs Observable implementation. See the RxJs Installation Instructions for details on patching additional methods into that implementation.
• rxjs: Same as rxjs-min, but adds the somewhat standard Observable.of and Observable.from.
• rxjs-all: The kitchen sink approach to Observables.
• zen: The zen-observable implementation.

Shortcut registration can be done as follows:

import 'any-observable/register/zen';

It's especially handy for more recent versions of Node.js (and many test runners), that offer a --require flag:

$ ava --require=any-observable/register/zen test.js
