Master the Rails Asset Pipeline: Best Practices for Apps & Gems
summary
Explains exact fixes not fluff: shows three ways to ship assets in gems (pin vendor files for importmaps, bundle JS into the gem, or publish an npm package), compares Sprockets vs Propshaft (Propshaft only does four things: fingerprinting, dev server, minimal transpile, load paths), demos with AO and Marksmith sample repos so code actually runs, calls out surprising duplication (37signals included) and when middleware, rake tasks, or symlinks are practical.
