Trailblazer A New Architecture For Rails

on YouTube ↗32m

" summary

Trailblazer claims to be a thin architecture on Rails that extracts high‑level endpoints into operations (one public method, process), moves validation into reform form objects, and moves view fragments into cells; it changes file layout to app/concepts, keeps models persistence‑only, lets operations run in background workers, be reused by controllers, consoles and tests, accept JSON or XML, and handles roughly “75%” of common create/validate/save flows while making each use case a small, testable class.
