RxJS-WinJS 1.0 - WinJS Bindings for the Reactive Extensions for JavaScript


This project provides Reactive Extensions for JavaScript (RxJS) bindings for WinJS which includes support for HTML DOM objects to abstract over the event binding and Ajax requests via promises. This also bridges to HTML5 features such as Web Workers, WebSockets, MutationObservers and more, in addition to support for sensors as well. The RxJS libraries are not included with this release and must be installed separately.


There are a number of ways to get started with the WinJS Bindings for RxJS.

Download the Source

To download the source of the WinJSBindings for the Reactive Extensions for JavaScript, type in the following:

git clone
cd ./RxJS-WinJS

There are lots of ways to contribute to the project, and we appreciate our contributors.

You can contribute by reviewing and sending feedback on code checkins, suggesting and trying out new features as they are implemented, submit bugs and help us verify fixes as they are checked in, as well as submit code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the Rx Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.
