I'm trying to do my research in comparing <#C67HDJ...

# koin

I'm trying to do my research in comparing #C67HDJZ2N with #C5FT9Q36G, #C0B8ZTWE4 mostly (I've been told about #C0BLU9K96 too)

This is for server only usage (which I think cuts out dagger hilt for me) so perhaps my usage is simpler than a lot of what some kotlin DI tools are doing

So far, the consensus online is really mixed. However, one of the main sticking points I see debated is that #C67HDJZ2N is not compile time checked, as #C5FT9Q36G is

However, I have tried out #C67HDJZ2N in a part of our codebase using the annotations + ksp compiler plugin. Does this not now mean koin can be considered compile time safe for the dependency graph? Or is it still required to check things that #C5FT9Q36G handles automatically

In usage though, I do prefer the annotation setup Koin has vs Dagger. So I'd like to use koin if possible..

Hi @Adam Jarvis, yes...annotations is bringing the compile time safety aspect to Koin.

[Adam Jarvis]

That’s great, thanks

Another common item I’ve seen is that koin isn’t aligned with the Jakarta @inject annotations?

[Kibet Theophilus]

not sure what you mean by "they are not aligned"

Basically, posts I’ve read have said apparently not using this means it’s hard to move away from koin in the future

I’m coming from having only used spring boot as DI - other than that I’ve always hand wired everything

I’m unsure of the pros / cons of following the JSR-330 spec

[Kibet Theophilus]

@Adam Jarvis I am not sure about this too, so I can't provide an answer.

[Adam Jarvis]

Perhaps @arnaud.giuliani could answer 🙌

Koin Annotations does not support @Inject for now. You have more details here about current annotations: https://insert-koin.io/docs/reference/koin-annotations/definitions

[Adam Jarvis]

Is there an accepted plan to allow it to recognize them in the future?

I’d be happy to take a look at working on that as a feature for koin

[arnaud.giuliani]

You can open a featue request on Koin Annotations Github 👍

[Adam Jarvis]

Yeah 😅

I meant, I’m happy to take a look at contributing and seeing if I could introduce it as a feature

However before going down the rabbit hole, I wanted to check if you’d even accept that as a feature

Context: I like koin, and want to use it in my company. However one sticking point that worries some people is that it cannot be used with the @inject annotation set

[arnaud.giuliani]

yeah. I would say that we need to identify what's expected behind @inject annotation as standard behavior. But shouldn't be complex to add it to current annotations
