🛠️ Custom config.x Settings

Rails provides a convenient config.x namespace to store custom configuration in a centralized place. You can define arbitrary settings in config/application.rb and override them per environment in config/environments/*.rb. This keeps your magic numbers or feature flags organized and accessible throughout the app via Rails.configuration.x.

# config/application.rb
module MyApp
  class Application < Rails::Application
    # Define default custom settings
    config.x.api_timeout_seconds = 5
    config.x.feature_flags = { new_checkout: false }
  end
end

# config/environments/production.rb
Rails.application.configure do
  # Override in production
  config.x.api_timeout_seconds = 10
  config.x.feature_flags[:new_checkout] = true
end

Now you can call Rails.configuration.x.api_timeout_seconds anywhere in your code or initializers.
