Thanks for the response! So, for example, https://github.com/rozag/kozy-redux is written entirely in Kotlin, but it should also explicitly support the common platform somehow?

Yes, it should be built as a multiplatform library (with common, jvm and js parts). If it does not contain any deps on JVM world, it would be relatively easy to rebuild it in such way

Thanks. From the looks of it, there’s no JVM parts there.

You’ll want to specifically look at the build.gradle files. You’re looking to see if it has 3 modules, each w one of the following plugins: kotlin-platform-common kotlin-platform-jvm kotlin-platform-js The kotlin plugin actually relies on the java plugin, which makes it a jvm lib.
