Heroku: Build CSS using Compass/SASS for Clojure application

For our latest project (photo duel site) we have decided to use the Clojure language. In order to make it easy for us at the beginning, we chose Heroku to host our application so that we don't have to manage deployment, hosting and database by ourselves.

So far I'm really happy about this choice, but nevertheless there were a few issues along the way. In order to reuse some CSS stuff and knowledge from our other project (Albumino) we had to find out how to compile our CSS files using Compass. So how do you do that when using Heroku? First let's look how your Clojure application is being built.

Using The Command Line

The Command Line (CLI) is the primary user inferface of many Unix-like operating systems. Over the years it has evolved into a powerful thing which will make your life a lot easier if you invest some time to learn it.

This post is based on one of my internal presentations which I created for my teammates at Netsafe. It assumes that you are already familiar with the CLI.
