Koin vs Dagger (Service Locator vs D.I.)
summary
Compares Koin 2.0 and Dagger by showing how each resolves dependencies: Koin uses Koin 2.0 runtime resolution with reified types and the lazily injected helper, while Dagger uses Dagger compile-time codegen that generates factories and verifies graphs at build time. Notes tradeoffs: compile-time guarantees versus runtime flexibility, build-time and onboarding costs, scoping behavior, and how constructor injection forces testability and reveals bad smells; concludes both give separation of concerns and can even be combined depending on team and project constraints.
