Cask: a Scala HTTP micro-framework
object MinimalApplication extends cask.MainRoutes{
@cask.get("/")

"Hello World!"

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