Zeitwerk is an efficient, thread-safe code loader for Ruby that maps file paths to constant paths. It supports autoloading, eager loading, reloading, and is the loader used by Ruby on Rails.

Use cases

  • autoload Ruby classes and modules from file paths
  • eager load an entire Ruby application or gem
  • reload code in development without restarting
  • load code in a thread-safe web server environment
  • enforce file-constant naming conventions in a project
  • set up autoloading for a Ruby gem

When to choose

  • you are building a Ruby gem or application and want convention-based autoloading
  • you need thread-safe lazy loading or eager loading
  • you want Rails-style autoloading outside Rails

When to avoid

  • your project does not follow file-path-to-constant-path conventions and cannot be restructured
  • you need dynamic loading of files with arbitrary names
