Structure a Ruby gem for Rails integration by using proper ActiveSupport.on_load hooks for lazy loading and setting up Railtie or Engine components to avoid common loading order issues. This ensures your library loads correctly within Rails applications.

Zero-runtime-dependency Ruby gem development requires avoiding unnecessary external libraries, implementing class macro DSLs cleanly, and using Minitest for testing. This approach ensures maintainable, performant gems that are easy for other developers to adopt.

Set up Minitest for a Ruby gem by following established test configuration patterns from production-ready libraries. This provides a lightweight testing framework that avoids the overhead of larger testing dependencies while ensuring reliable test coverage.

Support multiple database adapters in a Ruby gem by implementing modular adapter patterns that isolate database-specific logic. This allows your library to function across different database systems without coupling to a single backend.

Use ActiveSupport lazy loading in gem development when your library integrates with Rails to prevent constant loading conflicts and improve boot performance. Proper lazy loading ensures your gem initializes components only when Rails requires them.

Avoid anti-patterns in Ruby gem development such as improper loading order, excessive runtime dependencies, and tightly coupled Rails integration. Following established class macro DSL patterns and modular organization prevents maintainability issues.
