func main() {

}

 GOOS=js GOARCH=wasm go build -o  main.wasm

bjorn3 commented on issue #8841:

GOOS=js uses a Go specific syscall interface which is only implemented by the JS code available at https://github.com/golang/go/blob/master/misc/wasm/wasm_exec.js This only works in the browser and with Node.JS and is incompatible with any native WASM runtime. For Wasmtime and other native WASM runtimes you have to use GOOS=wasip1 instead and are not allowed to use the syscalls/js package.
