Transferable Detection? about remote-web-streams HOT 2 CLOSED

Both new RemoteWritableStream() and fromWritablePort() take an optional options object which can have a transferChunk callback. It receives a chunk, and it can return a transfer list that will be passed as second parameter to postMessage(). (It looks like I didn't write any documentation about this yet, sorry about that! 😅)

const { writable, readablePort } = new RemoteWebStreams.RemoteWritableStream({
  transferChunk(chunk) {
    if (chunk instanceof Uint8Array) {
      return [chunk.buffer];
    }
    return [];
  }
});
worker.postMessage({ readablePort }, [readablePort]);
const writer = writable.getWriter();
writer.write(new Uint8Array([1, 2, 3, 4])); // will be transferred to other end

Thank you. This was perfect and the library is exactly what I needed.
