Microsoft: jQuery 2.0 Will Add Full Support For Windows Store Apps

The next version of jQuery, the popular JavaScript library, will drop support for Internet Explorer 6, 7, and 8, but that doesn’t mean Microsoft isn’t very bullish about getting developers to use jQuery 2.0 and HTML5 to develop “a new wave of jQuery-based Windows Store applications.”

As Microsoft announced today, Microsoft Open Technologies, the company’s wholly owned open source-focused subsidiary, and the JavaScript experts at appendTo, have been working with the jQuery community to ensure that the next version of the framework offers full support for Windows Store applications.

Developers could obviously already build Windows Store/Metro apps with jQuery, but thanks to this cooperation, the process for developing jQuery 2.0-based Windows Store applications should now be smoother, safer and more streamlined.

As appendTo’s director of support Jonathan Sampson wrote in today’s announcement, jQuery always met the language criteria for Windows Store applications, but “Windows 8 exposes all the WinRT APIs within the HTML5 development environment, which comes with a new security model that made some code and common practices of jQuery flagged as unsafe in the context of a Windows Store application. AppendTo reviewed and re-authored portions of jQuery core to bring it into alignment with the Windows security model, as well as identified key areas where alternative patterns would need to be substituted for actually-used conventions.”

Even though Microsoft has always stressed this in the run-up to the Windows 8 launch, quite a few developers are still unaware that they can use their web development skills to write desktop apps for Windows 8 and Windows RT. Developers, by the way, can already use a number of other open-source JavaScript frameworks, including backbone.js, Knockout.JS and YUI.

As Deve Methvin, the president of the jQuery Foundation noted in a prepared statement today, that’s also something his organization is interested in. “The jQuery team is excited about the new environments where jQuery 2.0 can be used. HTML and JavaScript developers want to take their jQuery knowledge with them to streamline the development process wherever they work. jQuery 2.0 gives them the ability to do that in Windows 8 Store applications. We appreciate the help from appendTo for both its patches and testing of jQuery 2.0 and MS Open Tech for its technical support.”
