title: Rails asset pipeline with ES6 modules and browserify
body: <p>I'm trying to implement something with the rails asset pipeline that is proving harder than I'd hoped.</p>
  
  <p>In order to structure the app cleanly, I plan to use a module system for the javascript. For this I want to use CommonJS modules, but I'd like to write them using the new ES6 syntax for future compatibility.</p>
  
  <p>I've found the ES6 module transpiler extension for the asset pipeline, which works well, but this only converts it into the CommonJS format. I still need to get this into JS that the browser understands. For that I'm looking at using Browserify but my problem lies in combining these 2.</p>
  
  <p>The module transpiler works in a per file basis, but browserify works by checking all of the files needed. The problem is that browserify can't use the original files as they're no in CommonJS format, they're in ES6, so it needs the transpiled versions, but because that happens in the pipeline, I can't point browserify at a file.</p>
  
  <p>Are there any ways around this?</p>
