Split routes into multiple files

If your routes file is overwhelmingly big, you can put your routes in multiple files and include each of the files with Ruby’s require_relative method:

config/routes.rb

YourAppName::Application.routes.draw do
  require_relative 'routes/admin_routes'
  require_relative 'routes/sidekiq_routes'
  require_relative 'routes/api_routes'
  require_relative 'routes/your_app_routes'
end
config/routes/api_routes.rb
YourAppName::Application.routes.draw do
  namespace :api do
    # ...
  end
end
