Hey friends, it's been a while!
It's time for another summer sale — starting today, you can get the book for 50% off. Just head on over to wasmgroundup.com, no discount code required.
So, if you've been meaning to pick it up (or you know someone who has), what better time than now?

I usually include a destkop/JVM client in Compose Multiplatform projects I work on as I think faster to iterate on. Just realised that also very useful to have a Kotlin/Wasm based client as Claude is able to drive it faster using following plugin
