Google: Hey, devs - grab ahold of our Chromecast pipe and work it
Next-gen Chrome apps factory on the way
Google is working on a webbified development to build the “next generation” of Chrome Apps.
One of the search titan’s employees has revealed the existence of a Chrome App-based development environment codenamed Spark.
Google’s proto IDE contains a library of GUI widgets built using the Polymer Project.
Polymer is an early-stage, pre-alpha, effort for building apps using HTML Web Components.
If this sounds like a no-limits-on-your-imagination type of dream, it is. Currently, there are no actual components. What you currently have, according the the project's FAQ, is: “A solid technical foundation [who] are working feverishly to make our ambitious vision a reality.”
Polymer works in "recent" versions of Chrome, Safari, Internet Explorer, and Firefox, the project said. What qualifies as "recent", you ask? On IE it's nothing earlier than version 9, which has "insufficient" DOM support.
The source for Spark IDE is public on GitHub. There’s no further information on roadmap. ®
