npm i

DTLS Server API:

// Key is the only required option. The rest are optional.
const options = {
  key:                '...', // Path to the server's private key.
  identityPskCallback: null, // Callback. PSK resolver, if we're using PSK.
  handshakeTimeoutMin: 3000, // How many milliseconds can a handshake subtend before being dropped?
  debug:               0     // How chatty is the library? Larger values generate more log.
};

const dtlsserver = dtls.createServer(opts, socket => {
  // socket is a duplex stream.
  socket.on('data', data => {
    // Handle incoming data.
  });
});
