Does anyone know if it's possible to implement React's useState hook in pure kotlin? Or does it rely on JS's var magic?

@Big Chungus, check this Jetbains Sample.

I did and they use react's rawUseState, which I want to avoid

@Big Chungus, I'm new with react.
What do you mean with react's rawUseState?

[Big Chungus]

rawUseState is just react's useState renamed on kotlin external declarations

[Big Chungus]

Anyways, figured it out

@Big Chungus how did you do it?

[Big Chungus]

Via delegates. Here's how https://gitlab.com/lt.petuska/kvdom/-/blob/feature/MPE_DOM_REWORK/kvdom/kvdom-hooks/src/jsMain/kotlin/lt/petuska/kvdom/hooks/useState.kt

@Big Chungus, I'm new with Kotlin.

What advantages does your project have over kotlix.html or kotlin-react?

[Big Chungus]

Main goal is VDOM lib for WASM that essentially mirrors what kotlinx.html does but on common code 🙂

[Big Chungus]

Allowing you to compile your entire web UI from common-only code for either js or wasm

[Big Chungus]

It's veeery experimental now, though and I'm reworking entire diffing algorithm

The link above is broken. Getting a 404.

[Big Chungus]

Yeah, the branch was merged

Try this https://gitlab.com/lt.petuska/kvdom/-/blob/v0.1.0-M2/kvdom/kvdom-core/src/commonMain/kotlin/lt/petuska/kvdom/core/module/hooks/useState.kt

That is really cool! I found the example usage in your project here: https://gitlab.com/lt.petuska/kvdom/-/blob/v0.1.0-M2/kvdom-sample/src/commonMain/kotlin/lt/petuska/kvdom/sample/index.kt
