I want to call a function when the net.serverCreate is up. It need to call this function when the server is started and not when a new connection appears. Event 'listening' dont fire...When I start the server I want to check something in Mysql data-base... How to execute functions when server starts? My app:

var server = net.createServer(function (socket) {
    socket.on('listening', function () {
        console.log("Console is listening! "); //Its dont log
    });


    socket.on('data', function (message) {      

    });

    socket.on('end', function () {
        socket.end();
    });
});
server.listen(1337,function(){ 
    console.log("Server starts succefully"); //Its working!
});

Event 'listening' dont fire

The callback to createServer is handed a client Socket. Client-side sockets don't listen for requests; they make requests. So a listening event is never emitted by Sockets

On the other hand, net.createServer() returns a server-side socket(similar to Java's ServerSocket)

This should work.

server.listen(1337,function(){ 
//mysql db query
});

The callback to listen is executed when the server is bound to the specified port, i.e., when the server starts listening. The last parameter to listen is added as a listener for the listening event.

Another way to monitor the server-start event is:

server.on('listening', function() {
//mysql db query
});

Listening event
