Try it
(module
  (import "console" "log" (func $log (param f32)))
  (func $main
    f32.const 2.7 ;; load a number onto the stack
    f32.ceil ;; round up
    call $log ;; log the result
  )
  (start $main)
)
const url = "{%wasm-url%}";
await WebAssembly.instantiateStreaming(fetch(url), { console });
