I used that for a while, and it worked for me too, but found that it took a long while to reload the app, and also some time for node-inspector to bring up all the files.

There's babel-watch (https://github.com/kmagiera/babel-watch) that attempts to solve some of that, but I found that support for flags (debug) was limiting.

In the end, I figured why not just put together the fundamental tools. I use tmux and it's really not a problem to run multiple commands. Reloads are very rapid, and I never have to worry about things like flags or any other configuration being passed to the underlying tools, even as the ecosystem continues to evolve.
