Dependency Injection Containers vs Hard-coded Constants
Dependency injection (DI) is a somewhat contentious topic in the Ruby community. Some argue that DI containers are unnecessary complexity cargo-culted from Java. Some argue that DI is the path to cleaner, simpler, more-testable code. In this article, I want to compare and contrast two approaches: hard-coded constants versus using a DI container. The difference might not be as big as you think!
