Defined in:
lib/orange-core/middleware/static.rb

Overview

The Orange::Middleware::Static middleware intercepts requests for static files (javascript files, images, stylesheets, etc) based on the url prefixes passed in the options, and serves them using a Rack::File object.

This differs from Rack::Static in that it can serve from multiple roots to accommodate both Orange static files and site specific ones. urls and root act the same as they do for Rack::Static. Only :libs option acts specially.

Each lib is responsible for responding to static_url and static_dir

Examples:

  use Orange::Middleware::Static  :libs => [Orange::Core, AwesomeMod]
  use Orange::Middleware::Static  :libs => [Orange::Core, AwesomeMod],
                                  :urls => ["/favicon.ico"]

=> Example 1 would load a file root for Orange::Core and Awesome Mod
    Orange::Core static_url is _orange_, and dir is the
    orange lib/assets folder
=> Example 2 would also redirect favicon.ico to the assets dir

Note that as a general rule, Orange will assume everything static to be in an /assets/ subfolder, therefore, ‘/assets’ will be prepended to the url given by static_url Also note, that since this is the case - setting up a match for general ‘/assets’ could yield unpredictable results

a static_url corresponds to the :module => in the add_css and add_js helpers
