KMP Dependency Injection

Cross-platform dependency injection with Koin.

Koin Multiplatform Setup

Dependencies

// build.gradle.kts (shared module)
sourceSets {
    val commonMain by getting {
        dependencies {
            implementation("io.insert-koin:koin-core:${koinVersion}")
            implementation("io.insert-koin:koin-test:${koinVersion}")
        }
    }
    val androidMain by getting {
        dependencies {
            implementation("io.insert-koin:koin-android:${koinVersion}")
        }
    }
}

Module Definition

// commonMain/kotlin/di/AppModule.kt
val sharedModule = module {
    // ViewModels (Android) / ScreenModels (multiplatform)
    factory { HomeViewModel(get(), get()) }
    factory { DetailViewModel(get()) }

    // Use Cases
    factory { GetUsersUseCase(get()) }
    factory { GetUserDetailUseCase(get()) }

    // Repositories
    single<UserRepository> { UserRepositoryImpl(get(), get()) }

    // Data Sources
    single { UserApi(get()) }
    single { createDatabase(get()) }
}

Platform Modules

// androidMain/kotlin/di/PlatformModule.kt
val androidPlatformModule = module {
    includes(sharedModule)

    // Android-specific dependencies
    single { android.content.Context() }
    single { PlatformConnectivityMonitor(get()) }
    single { PlatformFileService(get()) }
}

// iosMain/kotlin/di/PlatformModule.kt
val iosPlatformModule = module {
    includes(sharedModule)

    // iOS-specific dependencies
    single { PlatformConnectivityMonitor() }
    single { PlatformFileService() }
}

Koin Start

Android

// androidMain/kotlin/MyApp.kt
class MyApp : Application() {
    override fun onCreate() {
        super.onCreate()
        startKoin {
            androidContext(this@MyApp)
            modules(androidPlatformModule)
        }
    }
}

iOS

// iosMain/kotlin/di/KoinInit.kt
fun initKoin() {
    startKoin {
        modules(iosPlatformModule)
    }
}

// Called from Swift
// KotlinKMMSharedKt.doInitKoin()
