I have a KMM project. It has one module storage, which implements a SqlDelight DB, per the SqlDelight Documentation (it’s worth noting that docs specify using implementation() for dependencies). I have a second module feature which has a dependency on the storage module, like so:

sourceSets {
    val commonMain by getting {
        dependencies {
            implementation(project(":shared:storage"))
        }
    }
}

In my feature module, I can see/import/use classes and objects from the SqlDelight library:

import app.cash.sqldelight.EnumColumnAdapter

...
val someValue = EnumColumnAdapter<MyEnum>().encode(someEnumValue)

That seems … not right? SqlDelight is an implementation detail of the storage module, and should not be exposed to other modules that have a dependency on storage. What am I missing here? I’m a bit of a novice with gradle, so perhaps it’s something obvious.

#squarelibraries might be a better channel to ask 🙂

Since storage is the module that generates the queries and schemas, that code is added to the module’s source set. So your feature module gets access to those non-internal/private APIs, just like any other code.

implementation just means that APIs from :shared:storage won’t be further exposed to other modules that pull in feature module.

Thanks @Kirill Zhukov, I didn’t know #squarelibraries exists 😄

I guess I thought that same logic would apply … because I use implementation("app.cash.sqlDelight") in :shared:storage, so none of the sql delight api’s would be further exposed to things (like :shared:feature) that pull in the storage module.
