Porting Prezi to Elm in 99 lines of code

Elm is a statically-typed functional programming language. Its compiler produces safe JavaScript which is guaranteed to be free of runtime exceptions. Moreover Elm is packed with a bunch of powerful abstractions which let us build visual and reactive Web applications in a few lines of code.

As an example, I show the implementation of a simple framework for building Prezi-like presentations. It's just 99 lines of code!

def Secured[A](username: String, password: String)(action: Action[A]) = Action(action.parser) { request =>
  request.headers.get("Authorization").flatMap { authorization =>
    authorization.split(" ").drop(1).headOption.filter { encoded =>
      new String(org.apache.commons.codec.binary.Base64.decodeBase64(encoded.getBytes)).split(":").toList match {
        case u :: p :: Nil if u == username && password == p => true
        case _ => false
      }
    }.map(_ => action(request))
  }.getOrElse {
    Unauthorized.withHeaders("WWW-Authenticate" -> """Basic realm="Secured"""")

# The best way would be to create a group able to modify the "/etc/hosts" file:
# $ sudo addgroup host-manager
# $ sudo chgrp host-manager /etc/hosts
