Cask – Scala HTTP micro-framework

Cask is a simple Scala web framework inspired by Python’s Flask project. Cask allows you to define your web applications endpoints using simple function defs that you already know and love, annotated with the minimal additional metadata necessary to work as HTTP endpoints.

It aims to bring simplicity, flexibility and ease-of-use to Scala web servers, avoiding cryptic DSLs or complicated asynchrony.

This is free and open source software.

It turns out that function defs already provide almost everything you need in a HTTP endpoint:

• The parameters the endpoint takes
• If any parameters are optional, and their default values
• The ability to return a Response

Cask extends these basics with annotations, providing:

• What request path the endpoint is available at
• Automated deserialization of endpoint parameters from the respective format (Form-encoded? Query-string? JSON?)
• Wrapping the endpoint’s function def with custom logic: logging, authentication, …
