Propshaft and the Modern Asset Pipeline
summary
Propshaft replaces sprockets as Rails 7’s minimal asset pipeline: it drops transpiling and bundling, keeps and improves fingerprinting, and auto-discovers asset folders from gems and apps. It boots an Assembly that builds a load path hash, serves digested assets in development, writes a manifest for production, and uses a file-watcher to refresh caches. Integrates with importmaps or JS/CSS bundling gems (esbuild, rollup, bun) and skips digesting already-digested bundles. drops bundling and transpilation 100 commits in two months
