Node.js TCP Socket - if either of them breaks, they'll keep trying to reconnect

client.js

var net = require('net');

//
// Client
//

function openSocket() {
    var socket = net.connect(3e3);
    socket.setKeepAlive(true);
    socket.on('connect', onConnect.bind({}, socket));
    socket.on('error', onError.bind({}, socket));
}

var interval;
function onConnect(socket) {

    console.log('Socket is open!');

    interval = setInterval(function() {
        var msg = parseInt(+new Date) + '';
        socket.write(msg, function() {
            console.log('Sent:', msg);
        });
    }, 500);
}

function onError(socket) {

    console.log('Socket error!');

    // Kill socket
    clearInterval(interval);
    socket.destroy();
    socket.unref();

    // Re-open socket
    setTimeout(openSocket, 1e3);
}

openSocket();

server.js

var net = require('net');

//
// Server
//

var server = new net.Server();

server.on('connection', function(socket) {

    console.log('Socket is open!');

    socket.setEncoding('utf8');
    socket.on('data', function(data) {
        console.log('Received:', data);
    });

    socket.on('error', function() {
        console.log('Socket error!');
    });
});

server.listen(3e3, function() {
    console.log('Server is listening!');
});

Printing the error is a simple fix. in the 'error' listener; change the console log to 'console.log(error);' this will output the error instead of the verbiage he has written.
