For me I can mention ConfigurableDI is pretty handy thing

Something like this

class MyInitializer : Initializer<Unit> {
  override fun create(context: Context) {
    val module = DI.Module("myModule") {
      ...
    }
    ((context as DIAware).di as ConfigurableDI).addImport(module)
  }
}

But It has its cost. Decoupling your code like this it’s even much easier to forget to add binding of something (as we don’t have graph integrity safety)

And what is your favorite thing?

Not sure I have a favorite. It generally just works. Lots of integration points, customizability, easy and clean to configure (especially with the

new

function recently added, inspired by Koin), Seems relatively performant at startup time, though I wonder if KSP could help improve this even more in the future by moving some runtime init to compile time.

I even wrapped it with own wrappers 🙂 So instead of this:

bind<Repository>() with singleton { new(::RepositoryImpl) }

I write this:

bind<Repository>() with singletonOf(::RepositoryImpl)
