Investigate WebAssembly.instantiateStreaming

juniorrojas opened this issue a year ago · comments

Currently using WebAssembly.instantiate.

async function loadWasm() {
  const response = await fetch("algovivo.wasm");
  const bytes = await response.arrayBuffer();
  const wasm = await WebAssembly.instantiate(bytes);
  return wasm.instance;
}

but WebAssembly.instantiateStreaming might be a better option.

No need to do response.arrayBuffer() if we use WebAssembly.instantiateStreaming.

async function loadWasm() {
  const wasm = await WebAssembly.instantiateStreaming(
    await fetch("algovivo.wasm")
  );
  return wasm.instance;
}
