TL;DR: Use tsc-watch

I’ve spent some time researching how to get hot-reloading working with Node & TypeScript. Due to the mess that is the JS dev ecosystem, finding a solid solution took me longer I expected for this kind. Hopefully this post will save you that effort.

The best solution I found is using tsc-watch. Install it as a dev dependency and set tsc-watch –onSuccess 'node .' as your start script.

That’s it, happy hacking.
