// Setting up WebSocket for binary data as ArrayBuffer
const ws = new WebSocket("ws://localhost:8080");
ws.binaryType = "arraybuffer";

ws.onmessage = (event) => {
  if (event.data instanceof ArrayBuffer) {
    // Process binary data
    const view = new Uint8Array(event.data);
    console.log(`Received binary data of ${view.length} bytes`);
  } else {
    // Process text data
    console.log(`Received text: ${event.data}`);
  }
};

// Sending binary data
const binaryData = new Uint8Array([1, 2, 3, 4]);
ws.send(binaryData.buffer);
