A Frontend Developer’s View of a Full-stack Kotlin Application

on YouTube ↗31m

" summary

A working full‑stack Kotlin prototype: a Ktor server with an in‑memory database, a Kotlin/JS React web client using JS wrappers, and shared business models and RPCs compiled from one Multiplatform codebase. It uses Kotlin Multiplatform (expect/actual) for platform glue, kotlinx.serialization for JSON, Ktor and React (wrappers) with Gradle build config, shows IDE navigation from frontend call to backend implementation, includes JUnit and enzyme-based tests, and the posts/users/comments demo is available on GitHub and runs end‑to‑end.
