Does this skill support Devise or Sidekiq?

No, this skill follows the DHH philosophy of avoiding those gems in favor of custom authentication and database-backed queues like Solid Queue.

What is the DHH Rails Style?

It is an opinionated approach to Rails development used at 37signals, emphasizing REST purity, fat models, Hotwire, and minimal external dependencies.

Can I use this for frontend development?

Yes, it provides specific guidance on using Turbo and Stimulus for interactivity and modern native CSS with layers and OKLCH colors.

How does it handle testing?

It favors Minitest and Rails fixtures over RSpec and FactoryBot, prioritizing the standard Rails testing suite for simplicity and speed.

API Development

Implements 37signals' opinionated Ruby on Rails conventions to build lean, maintainable, and REST-pure applications.

About

This skill transforms Claude into an expert on the '37signals way' of Ruby on Rails development, as championed by David Heinemeier Hansson (DHH). It provides deep domain expertise for building applications that prioritize vanilla Rails patterns, RESTful purity, and Hotwire for the frontend while avoiding unnecessary abstractions like service objects or heavy JS frameworks. It is ideal for developers who want to follow the 'One Person Framework' philosophy, utilizing database-backed queues, thin controllers, and rich domain models to ship software faster and with less complexity.

Key Features

Implements 'fat models' using horizontal concerns and state-based records
Prioritizes Minitest and fixtures for simplified, fast-executing test suites
0 GitHub stars
Configures Hotwire (Turbo/Stimulus) for interactive frontends without SPA complexity
Enforces RESTful resource mapping over custom controller actions
Replaces common gems with native Rails features and database-backed solutions

Use Cases

Refactoring existing Rails code to follow 37signals/Basecamp architecture patterns
Performing code reviews to ensure alignment with DHH’s 'clarity over cleverness' standards
Building new features using the 'One Person Framework' philosophy and REST purity
