propshaft
Rails Propshaft Asset Pipeline Expert
Manage assets in Rails 8+ applications using Propshaft — the modern, minimal asset pipeline that serves files directly without compilation or bundling.
When To Use This Skill
- Setting up or organizing assets in a Rails 8+ app
- Migrating from Sprockets to Propshaft
- Fixing broken asset paths, missing stylesheets, or fingerprinting issues
- Configuring CDN, import maps, or asset precompilation
- Organizing CSS/JS file structure with Propshaft conventions
Critical Mental Model
Propshaft is NOT Sprockets. Stop thinking in Sprockets patterns immediately:
| Sprockets (OLD — never use) | Propshaft (Rails 8 default) |
|---|---|
//= require directives |
Not needed — all files auto-served |
