ruby - How to serve static files via Rack?

Question

I am currently developing a Rack-based application and want to redirect all file requests(e.g. filename.filetype) to a specified folder.

Rack::Static only supports file requests for a special folder(e.g. "/media").

Do I have to write an own Rack middleware or does a out-of-the-box solution exist?

Best regards

To redirect every request to a particular path, use Rack::File (for some reason this class is absent in recent documentation, but it is still part of the latest Rack):

run Rack::File.new("/my/path")

To redirect every request, and add an HTML index of all files in the target dir, use Rack::Directory:

run Rack::Directory.new("/my/path")

To combine several directories or serve only a some requests from the target dir:

map "/url/prefix" do
  run Rack::File.new("/my/path")
end

# More calls to map if necessary...

# All other requests.
run MyApp.new
