The app demonstrates how one can render jade templates server side. This can be helpful if the app/page in question should be easily crawlable/indexable by 'bots and client side only rendering would prevent that. I've used it successfully when both the server and client side rendering are turned on, then Google sees the server side rendered content and the client sees the client side rendered content and gets all the javascript interactivity.
To get started just clone the repo
git clone git@github.com:geapi/server-side-jade.git
cd server-side-jade
yes
bundle
rails s
