When you say "tell webpack where to put the files" what do you mean exactly? I recommend just making one bundle per "app" (can be configured as different entry points in your webpack config), and then using the outputs as standard Django static files. I found django-webpack-loader to be a little to magical for my taste and solving a problem that didn't really exist for me (the need for refreshless hot reloading).
