My project is ES6 (webpack + babel). Plato is great, but doesn't work with ES6 yet. I took a look at escomplex and the series of related packages, but it looks like the author is no longer maintaining this and it seems like it doesn't support ES6 anyways.
I'm using the ESLint complexity rule to at least warn me if there's an issue (it's set to warn at 6), but it's not the same as a pretty report.
Any suggestions?
