Defined in:
lib/vitrine.rb

Overview

A little idiosyncrastic asset server. Does very simple things:

  • sensible detector for default pages (they render from Sinatra view templates)

  • automatic compilation of CoffeeScript and SASS assets - just request them with .js and .css

and Vitrine will find them and compile them for you on the spot
