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:

package org.example.app

import org.scalatra._

class MyScalatraFilter extends ScalatraFilter {

  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.
