Scalatra is a free and open source web application framework written in Scala. [2] It is a port of the Sinatra framework written in Ruby. Scalatra is an alternative to the Lift, Play!, and Unfiltered frameworks.
Scalatra is an example of a microframework, a web software development framework which attempts to be as minimal as possible.
A full Scalatra application can be written in very few lines of code:
packageorg.example.appimportorg.scalatra._classMyScalatraFilterextendsScalatraFilter{get("/hello/:name"){<h1>Hello,{params("name")}</h1>}}From this tiny domain-specific language, Scalatra can be expanded into a minimal but full-featured model-view-controller web framework. For example, additional libraries can be attached in order to provide templating, object-relational mapping, and unit testing or behaviour driven development support.
