Jonas Bonér » Blog Archive » Real-World Scala: Dependency Injection (DI)
Update: Corrected typo in the Cake Pattern version of the last example. Update: Added a version of the last example using the Cake Pattern for easier comparison (see end of post). In this second post in the Real-World Scala series I am going to discuss how to implement/achieve Depenency Injection (DI) in Scala.

In this pattern, a trait (or class) can play one of three roles: the base, a core, or a stackable. The base trait (or abstract class) defines an abstract interface that all the cores and stackables extend, a

The Builder Pattern is an increasingly popular idiom for object creation. Traditionally, one of it's shortcomings in relation to simple constructors is that clients can try to build incomplete objects, by omitting mandatory parameters, and that error will only show up in runtime. I'll show how to make this verification statically in Scala. So, let's say you want to order a shot of scotch. You'll n
