Sinatra with Sprockets 2 (Asset Pipeline)
An example Sinatra app configured with the Sprockets 2 asset pipeline. A custom guard file is available to run the asset pipeline precompiler whenever an asset changes.
In this fork of sinatra-asset-pipeline, I've setup the project using sprockets-helpers and sprockets-sass.
To run:
$ bundle install
$ bundle exec guard
$ bundle exec rackup
