const dgram = require('dgram');

const socket = dgram.createSocket('udp4');

socket.on('listening', () => {
  const address = socket.address();
  console.log(`UDP Socket listening on ${address.address}:${address.port}`);
});

socket.on('message', (message, remoteInfo) => {
  console.log(`Received message from ${remoteInfo.address}:${remoteInfo.port} - ${message}`);
});

socket.on('error', (err) => {
  console.error(`Socket error:
${err.stack}`);
  socket.close();
});

// Send SCTP packet over UDP
socket.send(Buffer.from('hello'), 5000, '127.0.0.1', (err) => {
  if (err) {
    console.error(`UDP message send error:
${err.stack}`);
    socket.close();
  } else {
    console.log('UDP message sent to 127.0.0.1:5000');
  }
});

socket.bind(5001);

// Example of sending SCTP packet over UDP
// sctp.send(socket, Buffer.from('hello'), 5000, '127.0.0.1', 5001, (err) => {
//   if (err) {
//     console.error(`SCTP send error:\n${err.stack}`);
