draw(name)
public

Loads another routes file with the given `name` located inside the `config/routes` directory. In that file, you can use the normal routing DSL, but *do not* surround it with a `Rails.application.routes.draw` block.

# config/routes.rb
Rails.application.routes.draw do
  draw :admin                 # Loads `config/routes/admin.rb`
  draw "third_party/some_gem" # Loads `config/routes/third_party/some_gem.rb`
end

# config/routes/admin.rb
namespace :admin do
  resources :accounts
end

# config/routes/third_party/some_gem.rb
mount SomeGem::Engine, at: "/some_gem"

*CAUTION:* Use this feature with care. Having multiple routes files can negatively impact discoverability and readability. For most applications — even those with a few hundred routes — it’s easier for developers to have a single routes file.
