TypeScript and libraries such as jQuery (with .d.ts files)

You don’t need to compile jquery to typescript, you just need to use a definition file that tells Typescript how the JavaScript library works.

Get definitions here:
https://github.com/DefinitelyTyped/DefinitelyTyped

or from NuGet if using Visual Studio.

Then just write your typescript as normal, and declare your library if needed:

declare var library : libraryTypedName

for example jquery’s d.ts file already does this for you (check the bottom):

declare module "jquery" {
    export = $;
}
declare var jQuery: JQueryStatic;
declare var $: JQueryStatic;

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

Now in your .ts file when you type $ it should give you the typescript intellisense.

Now the only things you want to include in your bundleconfig / <script> are the .js files, both yours and jquery / other libraries. Typescript is COMPILE time only!
