gulp integration?

[phatpaul]

Is there any support for using this with gulp?
angular/tsickle#496 says "We're unlikely to do this, and instead leave it to a downstream project like https://github.com/theseanl/tscc ."

My gulpfile already uses closure-compiler but now I want to integrate a typescript library (https://github.com/pladaria/reconnecting-websocket) and I'm looking for a way to transpile the typescript library before closure-compiler.
