The Reactive Extensions for JavaScript (RxJS) are a set of libraries for composing and coordinating asynchronous and event-based programming that works across many JavaScript runtimes including all browsers and Node.js.

This set of libraries include:

• rx.js - Core library
• rx.aggregates.js - aggregation event processing query operations
• rx.binding.js - binding operators including multicast, publish, publishLast, publishValue, and replay
• rx.coincidence.js - reactive coincidence join event processing query operations
• rx.experimental.js - experimental operators including imperative operators and forkJoin
• rx.joinpatterns.js - join patterns event processing query operations
• rx.testing.js - used to write unit tests for complex event processing queries.
• rx.time.js - time-based event processing query operations.

There are multiple ways of getting started with the Reactive Extensions including:

In a Browser:

<script src="rx.js><script>

Along with a number of our extras for RxJS:

<script src="rx.aggregates.js><script>
<script src="rx.binding.js><script>
<script src="rx.coincidencejs><script>
<script src="rx.experimental.js><script>
<script src="rx.joinpatterns.js><script>
<script src="rx.testing.js><script>
<script src="rx.time.js><script>

Installing via NPM:

npm install rxjs
npm install -g rxjs

Using in Node.js:

var Rx = require('rx');

Installing all of RxJS via NuGet:

Install-Package RxJS-All

Or install via NuGet individual packages:

Install-Package RxJS-Main
Install-Package RxJS-Aggregates
Install-Package RxJS-Binding
Install-Package RxJS-Coincidence
Install-Package RxJS-Experimental
Install-Package RxJS-JoinPatterns
Install-Package RxJS-Testing
Install-Package RxJS-Time

Using RxJS with an AMD loader such as Require.js

require({
    'paths': {
        'rx': 'path/to/rx.js'
    }
},
['rx'], function(Rx) {
    var obs = Rx.Observable.returnValue(42);
    obs.subscribe(function (x) { console.log(x); });
});
