Scalatra is an HTTP micro-framework, written in the up-and-coming new language, Scala. Scalatra is used by LinkedIn, the BBC, the Guardian newspaper, games website IGN, social identity provider JanRain, the Wordnik online dictionary, and the British government’s new flagship website. It’s fast, battle-tested, and in production. This article introduces you to the simplicity of Scalatra micro-framework.
