This beta product for a firebase security compiler is written in typescript (by me) for node.js

https://github.com/firebase/blaze_compiler

Typescript has been a joy to develop in. The codebase is a mix of typescript and plain JS for some of the parsing.

There are a few interesting architectures patterns like a work around for no subclassing of Error by wrapping an error with a backwards chained decorator

(thanks to mindplay for that idea here https://typescript.codeplex.com/discussions/465345)

That product is still in it's infancy so gradually being refactored towards full modularisation, so its still a work in progress.

FYI: I use pycharm with the node.js plugin, and typescript compiles in the background without intervention, and I can step debug the program, and the line at the top off all the files transparent changes the stack traces back into TS.
