ERROR TypeError: dgram_1.default.createSocket is not a function

[regetskcob]

The following code...

  connect() {

    // Create tunnel socket with source knx address 1.1.100
    const knxClient = new KNXTunnelSocket("1.1.31");

    knxClient.on(KNXTunnelSocket.KNXTunnelSocketEvents.error, err => {
        if (err) {
            console.log(err);
        }
    });

    // Call discoverCB when a knx gateway has been discovered.
    knxClient.on(KNXTunnelSocket.KNXTunnelSocketEvents.discover,  info => {
        const [ip,port] = info.split(":");
        discoverCB(ip,port);
    });

    // start auto discovery on interface with ip 192.168.1.99
    knxClient.startDiscovery("192.168.178.28");

    const handleBusEvent = function(srcAddress: string, dstAddress: string, npdu: NPDU) {
      console.log(`${srcAddress.toString()} -> ${dstAddress.toString()} :`, npdu.dataValue);
    };

    const discoverCB = (ip: string, port: number) => {
      console.log("Connecting to ", ip, port);
      
      // Connect to the knx gateway on ip:port
      knxClient.connectAsync(ip, port)
          .then(() => console.log("Connected through channel id ", knxClient.channelID))
          .then(() => {
              console.log("Starting bus monitoring");
              knxClient.on("indication", handleBusEvent);
              knxClient.monitorBus()
          })
          .catch(err => {console.log(err);})
      };
  }

... is producing an error/exception inside the KNXClient code:

May you be able providing me help to solve this error? what is going wrong there?

Do not install with ng. knx-ip is a pure backend lib. No reason to use ng. Try with a simple npm install.
