Android, Compose, MP & Server - Inject them all with Coin
summary
Coin is a Kotlin DSL IOC container that drops Dagger-style codegen for a runtime container, claims Coin 4.0.0 is ready and requires Kotlin 2, and reports growth from 5 million to 11–12 million downloads per month. It shows concrete APIs: module/single/factory, byInject and byViewModel delegates, Compose helpers (coinInject, conViewModel), AndroidX Startup and lazy module loading to cut startup by ~25–45%, and KMP/ Ktor integrations with a KSP-based optional compile-time verifier.
