Using Kotlin for JS Client and JVM Server

on YouTube ↗33m

" summary

Kotlin compiles to JavaScript for production while Kotlin Multiplatform remains experimental; the workflow uses expect/actual declarations, multiplatform libraries like kotlinx.serialization, and Gradle to produce JVM server and JS client artifacts. A demo full‑stack app shares data classes, HTTP suspend APIs and validation logic between server and browser, reusing common modules compiled twice; iOS UI stays in Swift. Tooling works but needs explicit JS name exports, Gradle tasks for tests, and Xcode for iOS builds.
