Compatibility with Chrome DevTools Autosave

[NV]

Chrome DevTools Autosave doesn’t work with Sprockets (NV/chrome-devtools-autosave#27). The culprit of the problem is in the assets URLs — I cannot decipher the actual file path by its URL. For example, /assets/application.css may refer to either app/assets/stylesheets/application.css, lib/assets/stylesheets/application.css, or vendor/assets/stylesheets/application.css.

I wonder, how do I change assets URLs to one of the following?

• /app/assets/stylesheets/application.css (matches actual file path, perfect solution)
• /assets/application.css?source_url=app/assets/stylesheets/application.css (introduces source_url query parameter)

I think we'll handle this with Source Maps.

[NV]

I don’t think we will since files transformed by Source Maps cannot be edited.

They will have pointers to the source files.

They do, but in my case it doesn’t help at all since all resources become unable to edit in Chrome DevTools.
