scalatra-sample-API
This project does not include SBT, so you will need to install it via your package manager (brew install sbt on Mac OS X), or use an IDE plugin like the IntelliJ sbt plugin.
This sample project is used for my tutorial here: http://jieyanghu.com/2014/07/08/setting-up-a-barebones-hello-world-rest-api-using-scalatra/
