I'm playing with TypesScript, but the compiler complains when I use browser types such as HTMLCanvasElement. I guess I need definition files for these types. I bet there is a repository of definition files for the DOM and for most popular frameworks, but Google has not been able to help me find it.
Do you guys know of such a repository?
The lib.d.ts that is included in the source (http://typescript.codeplex.com/SourceControl/changeset/view/fe3bc0bfce1f#bin%2flib.d.ts) contains definitions for most of the DOM related stuff. If you are using Visual Studio, you should consider downloading the tools which includes a template where lib.d.ts is bundled.
If anything is missing, I think you can use the declare syntax.
