NodeJS TCP server multiple PORT et multiple Client

Je suis un développeur débutant Node Js, j'essaie de développer un serveur TCP asynchrone avec plusieurs clients et plusieurs ports sans bloquer la chaîne d'exécution. Ce code peut faire l'affaire?

var net = require('net');
 
var HOST = '127.0.0.1';
var PORT = 6969;
var PORT2 = 6967;
 
// Create a server instance, and chain the listen function to it
// The function passed to net.createServer() becomes the event handler for the 'connection' event
// The sock object the callback function receives UNIQUE for each connection
net.createServer(function(sock) {
 
    // We have a connection - a socket object is assigned to the connection automatically
    console.log('CONNECTED: ' + sock.remoteAddress +':'+ sock.remotePort);
 
    // Add a 'data' event handler to this instance of socket
    sock.on('data', function(data) {
 
        console.log('DATA ' + sock.remoteAddress + ': ' + data);
        // Write the data back to the socket, the client will receive it as data from the server
        sock.write('You said "' + data + '"');
 
    });
 
    // Add a 'close' event handler to this instance of socket
    sock.on('close', function(data) {
        console.log('CLOSED: ' + sock.remoteAddress +' '+ sock.remotePort);
    });
 
}).listen(PORT, HOST);
 
 
net.createServer(function(sock) {
 
    // We have a connection - a socket object is assigned to the connection automatically
    console.log('CONNECTED: ' + sock.remoteAddress +':'+ sock.remotePort);
 
    // Add a 'data' event handler to this instance of socket
    sock.on('data', function(data) {
 
        console.log('DATA ' + sock.remoteAddress + ': ' + data);
        // Write the data back to the socket, the client will receive it as data from the server
        sock.write('You said "' + data + '"');
 
    });
 
    // Add a 'close' event handler to this instance of socket
    sock.on('close', function(data) {
        console.log('CLOSED: ' + sock.remoteAddress +' '+ sock.remotePort);
    });
 
}).listen(PORT2, HOST);

Si ce code est correctement codé, j'ajouterai une fonction CRUD à l'intérieur de la section sock.on ( 'data', function (data) {... // HERE});
