TypeScript definitions for WinJS

Question

Where are TypeScript definitions for the WinJS library?

Actually why is WinJS not written in TypeScript in the first place?

Answer 1

The definitions for WinJS are here:

https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/winjs

WinJS pre-dates TypeScript. That's not to say they won't transfer it to TypeScript now given TypeScript 1.0 was officially announced last night.

Answer 2

There are also some definitions in the Official TypeScript repository found here: https://typescript.codeplex.com/SourceControl/latest#typings/

They might be the same as the one on DefnitelyTyped but i'm not sure.

Answer 3

It seems WinJS definitions on DefinitelyTyped are not updated which is sad. So best source today is probably WinJS github repo: https://github.com/winjs/winjs/tree/master/typings/winjs

Answer 4

I have a tutorial about when to use DefinitelyTyped vs Typings, as I found both of them to be very confusing.

TypeScript wasn't a think when WinJS was first created as well. Not everyone wants to use TypeScript, so to get web developers on board, I'd imagine that simply using JavaScript is a better starting point than requiring them to learn a new language (TypeScript) on top of learning the WinJS programming model.
