Hi Guys ^^,

I need to call this kotlin function from wasm index.html script.

@JsExport
fun submitJsonToKMM(jsonData: String) {
    
}

My index.html code

<script>

const editor = ace.edit("editor");

function submitJson() {
        const jsonData = editor.getValue();
        // Pass the JSON data to the KMM WASM project
        submitJsonToKMM(jsonData);
      }
</script>

It’s not working, getting submitJsonToKMM is not defined, Can anyone please help…

Depends on which output do you consume.
If it’s webpack output (dist) you need to configure Webapck in build.gradle.kts like:

browser {
    commonWebpackConfig {
        output = KotlinWebpackOutput("Foo", KotlinWebpackOutput.Target.VAR)
        ...
    }
}

Then at runtime you will have a Foo with Promise<Module>

In index.html, after mains script included you can do:

<script type="module">
    // to avoid writing await ..ю  every time 
    globalThis.Foo = await Foo;

    // call exported fun bar
    Foo.bar();
</script>
