These factors allow for a dramatically simpler and faster asset pipeline compared to previous options, like Sprockets.

So that's what Propshaft doesn't do. Here's what it does provide:

Configurable load path: You can register directories from multiple places in your app and gems, and reference assets from all of these paths as though they were one. Digest stamping: All assets in the load path will be copied (or compiled) in a precompilation step for production that also stamps all of them with a digest hash, so you can use long-expiry cache headers for better performance. The digested assets can be referred to through their logical path because the processing leaves a manifest file that provides a way to translate. Development server: There's no need to precompile the assets in development. You can refer to them via the same asset_path helpers and they'll be served by a development server. Basic…
