Your best bet is no integration at all. Just set up webpack to read from ./app/assets and output to ./public. Run it separately, preferable with a foreman Procfile for development (I've used Procfile.dev before).

You'll still likely want digested assets that integrate with Rails asset helpers. This has been done with Gulp[1] if that helps at all.

Thanks for the suggestion. I'd prefer some more automation, but that's also a possible solution.
