How would I create a module definition jszip? it has a namespace JSZip with new(): this; and (): JSZip but I can't figure out how to call it. I tried external fun JSZip as well as external class JSZip and both give errors.

@file:JsModule("jszip")

external class JSZip {
    constructor()

    fun file(name: String, data: String, options: FileOptions = definedExternally): JSZip 
    // ... Other functions, didn't bother to write them all out
}

external interface FileOptions { /* ... */ }

Try this?

OR try this:

external class JSZip {
    companion object {
        operator fun invoke(): JSZip
    }
}

1. Uncaught TypeError: _ref_anN6aXA_.JSZip is not a constructor
2. See image

Try adding: @JsName("default") to the external class JSZip maybe it's exported via default export.

We already have JsZip declarations in Kotlin Wrappers

I fixed WASM compatibility.
In next release (probably today) JSZip should work on WASM too.

Ready for use in Wrappers 2025.6.11 🎉🎉🎉
