Reactive Extensions for JavaScript

  • Artikel

We’re proud to announce the availability of Reactive Extensions for Javascript. This port brings the power of Reactive programming to JavaScript. It allows you to use the Rx combinators in JavaScript and it does this in a download size of less than 7Kb (GZipped). RxJS provides easy to use conversions from existing DOM, XmlHttpRequest and jQuery events to Rx push-collections, allowing users to seamlessly plug Rx into their existing JavaScript-based web sites.

To give RxJs a try, download the installer. The installer comes with documentation and a small animation-based sample. You can provide feedback on RxJS on the regular Rx forum, and of course help the Rx community to convert the 101 Rx samples to JavaScript!

For an introduction, watch the C9 Introduction to Reactive Extensions for JavaScript video:

    Use FromHtmlEvent, that method will call FromIEEvent on IE and FromDOMEvent on other browsers.

    Hello, RxJs is great, the documentation about it is a bit confusing to me. Several pages like this one say, "To give RxJs a try, download the installer." The link does not lead to an installer but a rar file. The other thing is that Rx.Observable.XmlHttpRequest does not work on my side. Is there any sample using this function? the sample in the blog comes without source code, and writing the source code from the sample does not work on my side, because this function is missing. Thx for any clarification. t

    adding rx.html.js did it. would be great to see this in the docu. "Assembly:  RxJS (in RxJS.dll)" is quite misleading :-)
