This beta product for a firebase security compiler is written in typescript (by me) for node.js https://github.com/firebase/blaze_compiler 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 https://github.com/firebase/blaze_compiler/blob/master/src/error.ts https://github.com/firebase/blaze_compiler/blob/master/src/e... (thanks to mindplay for that idea here https://typescript.codeplex.com/discussions/465345 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.
