A modern programming language that makes developers happier.

kotlinlang

I'm wondering what's the thoughts about making a Kotlin Library which uses the kotlin serialization compiler plugin? Or should I try to avoid using `@Serializable` for libraries?

I do not see that they are using it.
<https://github.com/ktorio/ktor/search?p=1&amp;q=Serializable> Only gives results for their unit testing

Why wouldn’t you?

I have a library, and the library can save its “storage” in a file and load from that file. Some sort of a file cache.

I'm just unsure how compiler plugins fully work and how it will effect users of this library. Example if some users using the library are using one version of kotlinx.serialization while the library is using another version.
Maybe all this doesn't matter at all?

That doesn't matter for compiler plugins, they only affect code in the project they are added to.  Of course, that's still an issue with the runtime, but that's expected.  You could use Kotlinx serialization internally and hide it with `serialize(data: MyData): String` style methods just fine.
