JavaScript IntelliSense in TypeScript File

Is it only possible to get IntelliSense in TypeScript files by referencing .ts files with own coded interfaces?

Is there a solution for existing JavaScript libraries?

You are able to get IntelliSense for other TypeScript files by using an external script reference directive at the top of your script:

///<reference path="someOtherScript.ts" />

As a side note, the TypeScript IntelliSense reference directive doesn't support the tilde operator like the JavaScript reference directive does. For example, if your script is located in "~/Scripts/foo/", in JavaScript you can reference:

///<reference path="~/Scripts/otherScriptFile.js" />

whereas in TypeScript you have to reference relative to the current file: 

///<reference path="../otherScriptFile.ts" />

More info about this can be found in section 11.1.1 Source Files Dependencies of the TypeScript Spec.

With regard to JavaScript IntelliSense in a TypeScript file, it currently appears to be not possible to get JavaScript reference IntelliSense.

As others before me have pointed out, you need the definition files.

The DefinitelyTyped GitHub repository provides an excellent (and growing) list of definition files for a lot of popular libraries.

You'll get intellisense support for every JS code (quality may vary), however the typescript specific stuff is only available when using apropriate definition files (*.d.ts).

You can find additional definition files in the source repository (> typings, currently only jQuery and WinJS/RT) http://typescript.codeplex.com/SourceControl/BrowseLatest
