# multiplatform

[Iliyan Germanov]

Hey folks, I have a Kotlin WASM JS web app that I published via GitHub pages on https://ivylearn.app. I used the :wasmJsBrowserDistribution Gradle task. However, the app only seems to work on Google Chrome (desktop). It's broken on:
• Safari (Desktop)
• Google Chrome (Android)
By broken I mean that click handling isn't working. Any ideas?

Here's the code:

Safari doesn't support WasmGC yet, so Kotlin/Wasm apps will not work. Don't know about mobile chrome.

Chrome on iOS also uses Apples WebKit without WasmGC too.

[Iliyan Germanov]

Got it. Thanks for the quick replies! Is there any ETA when it'll have full support? I'll just probably Google that 😄

Chrome (Android) might be something in my code cuz I use many Compose features. I'll investigate and let you know if I find the culprit.

Tl;dr;
• Kotlin WASM JS isn't yet ready for testing MVPs / validating ideas.
I've never tried Koltin JS - is it possible to re-use Compose multiplatform code like in WASM?

[Pablichjenkov]

The terminology is a bit wide. Kotlin-js is basically everything related to kotlin compilation/transpilation to js. In this particular case you might want to look for compose-js. Which is a target very similar to wasmJs but compiled to js not wasm

[Iliyan Germanov]

Awesome - seems like exactly what we need. Goal: "Re-use our Compose UI from commonMain for all platforms"

[Pablichjenkov]

Definitely doable yes.

[Iliyan Germanov]

I'm new to KMP is there any good resource/project that can help me migrate my setup from Kotlin WASM to Kotlin JS?

[Pablichjenkov]

You can actually have both in the same project.

[Iliyan Germanov]

I'll get rid of WASM for now cuz some libraries doesn't support it

[Pablichjenkov]

Check this one https://github.com/pablichjenkov/kmp-amadeus-api
It still uses the old KMP project structure. I have to migrate from share to composeApp

[Pablichjenkov]

GitHub is full of examples by the way

[Iliyan Germanov]

Yup, I just gotta dig. Btw, I migrated everything myself - it was easier than it sounds 😄

[Iliyan Germanov]

Thank you very much for the help! Kotlin JS saved my day 🙏
