const_missing_autoload

🔍 Lazy Loading with const_missing and Autoload​

Implement const_missing or use autoload to load modules or classes only when referenced. This approach reduces memory footprint and speeds up startup times in large applications.

module MyApp
  autoload :User, 'my_app/user'
  autoload :Order, 'my_app/order'
end

# Or custom const_missing
def MyApp.const_missing(name)
  require "my_app/#{name.to_s.downcase}"
  const_get(name)
end
