module Shoelace
  # The only reason this class exists is to clarify that we have a custom static file server after
  # `ActionDispatch::Static`. We could just use `ActionDispatch::Static` directly, but it would make the result of
  # `rake middleware` more difficult to understand, as the output would look like:
  #
  #    use ...
  #    use ActionDispatch::Static
  #    use ActionDispatch::Static # Why do we use the same middleware twice?
  #    use ...
  #
  # It is much more straightforward if it looks like:
  #
  #    use ...
  #    use ActionDispatch::Static
  #    use Shoelace::AssetProvider
  #    use ...
  #
  class AssetProvider < ActionDispatch::Static; end
