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
