133: Dependency Injection and Service Locators in a Kotlin world with Danny Preussler
A hotly debated topic at the moment is the use of a library like Dagger for dependency injection in the world of Kotlin. In this episode, we talk to Danny Preussler. Danny's a pro who's been around from the Java 1.0 days! He helps trace the history of dependency injection in Java all the way to today, in a Kotlin world where there exists alternatives like Koin and Kodine. We dive into how some of these use a Service Loader/Locator pattern and the subtle differences with dependency injection. Listen on for an action packed episode. http://fragmentedpodcast.com/episodes/133/
