I might add a transpiler for Typescript to my stack soon, if that language turns out as pleasant to work with as I've been hearing. If I do, it'll be the first time I use one. And I've been working with Node, in production, since 2013.
(That was a joke btw. Thanks for the info. The consensus seemed to be that Babel is the way to go, but if your variant works for you good to hear. I will still stay with it. I like ES6 imports in Node.)
