IDK much about the Android specifics, but it’s always nice to see the articles on framework-less DI.

If only to realize that framework-full DI is pretty darn useful 🙂

Meh, I only seem to use DI frameworks when forced to 😛

I have yet to see a convincing DI native approach that offers something even remotely similar to modules (which are a very important part of an effective DI solution).

after using gorgeous spring di i can't look on other "lightweight" di frameworks without tears (hello dagger2)

This is my kotlin dependency injection framework:

abstract class InjectionModule {
    fun <T : Any> singleton(provider: () -> T) = lazy(provider)
    
    fun <T : Any> provide(provider: () -> T) = TransientProviderProperty(provider)
}

class TransientProviderProperty<out T : Any>(private val _provider: () -> T) {
    operator fun getValue(thisRef: Any?, property: KProperty<*>) = _provider()
}

@deviant Interesting, to me it’s Spring DI that looks bloated and inconvenient, while Dagger 2 is lean and more statically typed too
