Cask 0.9.4: a Scala HTTP micro-framework

object MinimalApplication extends cask.MainRoutes{
  @cask.get("/")
  def hello() = {
    "Hello World!"
  }

  @cask.post("/do-thing")
  def doThing(request: cask.Request) = {
    request.text().reverse
  }

  initialize()
}

Cask is a simple Scala web framework inspired by Python's Flask project. It aims to bring simplicity, flexibility and ease-of-use to Scala webservers, avoiding cryptic DSLs or complicated asynchrony. Cask makes it easy to set up a website, backend server, or REST API using Scala

• Documentation

If you use Cask and like it, you will probably enjoy the following book by the Author:

• Hands-on Scala Programming

Hands-on Scala has uses Requests-Scala extensively throughout the book, and has the entirety of Chapter 14: Simple Web and API Servers dedicated to the library. Hands-on Scala is a great way to level up your skills in Scala in general and Cask in particular.
