TerrificTS is an experimental port of TerrificJs to TypeScript. The aim is to be able to use the TypeScript class-pattern in Terrific-modules and skins. I ported the whole script to TypeScript (maybe a bit overkill, as only the 'Module'-class is needed). The script works, but was not tested at all. Open the index.html in a browser to give it a shot.
If you are not familiar with TerrificJs, check out terrifically.org. The same goes for typescriptlang.org for TypeScript.
I recommend to check out the provided example to get a grip, but in short: You need at least the terrific-2.0.1.js aswell as the terrific-2.0.1.d.ts files from the root of this repository. Make sure to include the js-file in your Terrific-project as usual. The .d.ts-file contains the definitions to be used from TypeScript. You will obviously use TypeScript instead of plain JavaScript for the modules, take a look at the example.ts- aswell as the example-blue.ts-files which contain a basic template to be used for your modules and skins.
Do not forget to reference additional declaration-files like the jquery.d.ts if you need to work with it. Here's a list of declaration-files for many js-libraries.
