Android Architecture Design with Koin
summary
Koin is a Kotlin DI library focused on constructor injection and a small DSL; the project has 7K stars and about 5M downloads/year. Version 3 merges Android modules so you import one artifact, adds Jetpack Compose and Jetpack Navigation support including nav graph scoped viewModel, and documents scope patterns (scoped, factory, single, activity retain). A KSP-based compiler prototype aims to generate module bindings to remove repetitive get calls and a benchmark shows ~10,000 components generated in ~5s.
