Sinatra-rraoute provides `gget'/`ppost'/`ddelete'/... methods which work just like Sinatra's built-in `get'/`post'/`delete'/... methods, but which map named routes to functions so that they can be referenced in redirects etc. The `path' helper will return a route for a certain route name and the given values for this route and comes in handy in both, the controller/model component of the application, and the view where you can use it to render links, assets URLs, AJAX calls... The nestable `nnamespace' method is useful for API versioning and does not interfere with other namespace extensions for Sinatra.
