TypeScript定义文件

Question

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?

Answer 1

In addition to what @Christoffer has said for the DOM, @Boris Yankov has a really useful repository here: https://github.com/borisyankov/DefinitelyTyped with definition files for more than thirty, one hundred and thirty close to two hundred libraries(and counting!).

There's even a manager for the type definition files now: http://definitelytyped.org/tsd/

AND : Quite a lot of definition files are now on nuget: http://www.nuget.org/packages?q=TypeScript

Answer 2

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.
