so i got compose web working when rendering on a canvas, but for some reason i cannot get my code to render to the dom, trying to follow https://github.com/JetBrains/compose-jb/tree/master/tutorials/Web/Getting_Started loosely but no matter what i do this gets thrown..
Copy code
CompositionLocal LocalDensity not present
my main function is
Copy code
fun main() {
    renderComposable(rootElementId = "root") {
        console.log("rendering root element")

        Text("Test")
    }
}
and the index.html looks like so
Copy code
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Pentagame</title>
<!--    <script src="skiko.js"> </script>-->
</head>
<body>
    <div id="root"></div>
<!--    <canvas id="ComposeTarget" width="1024" height="720"></canvas>-->
    <script src="app.js"></script>
</body>
</html>

Maybe just a wild guess, but what happens if you wrap your 
renderComposable
invocation in this snippet?
Copy code
fun main() {
    document.addEventListener("DOMContentLoaded", {
        // renderComposable
    })
}

Wow, is canvas rendering already implemented? 😮

its not there yet.. some components will just break when rendering

Out of curiosity (no expectation of support), I provided a 
LocalDensity
and two other 
Local
requirements that arose; like this:
Copy code
fun main() {
    initLogTags()
    renderComposable(rootElementId = ROOT_DIV_ID) {
        CompositionLocalProvider(
            LocalDensity provides Density(1.0f),
            LocalLayoutDirection provides LayoutDirection.Ltr,
            LocalViewConfiguration provides JsViewConfiguration(Density(1.0f))
        ) {
            ...
        }
    }
}
This resulted in the browser logging, what I interpreted as, an end to the fun:
Copy code

🤷 Oh well, its interesting to try. This is with a more complex scene though, might pare it back and see if individual Text/Button components etc. render...
...no luck with plain 
Text
or a 
Surface
either.
