Cake Pattern and Self-Type Annotation

  • Probably the best coverage of the cake design pattern that I’ve ever seen can be found in the pages of the superb book entitled Scala Design Patterns by Ivan Nikolov (Packt Publishing).
  • As Ivan nicely describes it, “The cake design pattern is the Scala way to implement dependency injection. It is something that is used quite a lot in real-life applications, and there are numerous libraries that help developers achieve it. Scala has a way of doing this using language features, and this is what the cake design pattern is all about.”
