If You are such a person You can use activator and start Your journey with Spray and Slick using my seed.
Best way to do that is to use Typesafe Activator, but You can also clone my repository on github.
What i’ve got in package?In my seed I use: Spray.io 1.3.2, Slick 2.1.0, Akka 2.3.9 and H2 database (but You can use any database). For testing purposes there is Spec2 and additional helper for creating test data.
I’ve also prepared sample API so You can run it and test it out of the box.
