I guess the OP needs to use WebSockets on the server side. Please see this example.

Previous replies are not correct. OP is trying to use a QTcpServer with javascript client, so he's actually working on the server side. The correct Qt class for that is QWebSocketServer. The page also has examples, so should be straightforward.

@Taytoo So i nedd to use QWebsocket, but how can I include the .h file? As i said I put in .pro qwebsocket but the compiler cant found qwebsocket header file. Im new in qt, I suppose something its needed install?

As i said I put in .pro qwebsocket

It's

QT += websockets

as shown here https://doc.qt.io/qt-5/qwebsocket.html

With due respect, I do consider my reply correct since I pointed the OP to the Websokects echo server example, which according to its description:

The Echo Server Example shows how to create a simple server application that sends back the messages it receives, using the WebSocket API.

and looking at its source code, you can see clearly that it uses a QWebSocketServer

EchoServer::EchoServer(quint16 port, bool debug, QObject *parent) :
    QObject(parent),
    m_pWebSocketServer(new QWebSocketServer(QStringLiteral("Echo Server"), QWebSocketServer::NonSecureMode, this)),

and the .pro clearly shows how to reference the Qt Websockets module:

QT = websockets

TARGET = echoserver
CONFIG   += console
...

@Pablo-J-Rogina yes as I said in .pro added websockets BUT can't include in project, always show error QT= websockets file not foud. Here the problem id not the use it the example, I think its the configuration.
Here show:

"Project ERROR: Unknown module(s) in QT: websockets"

@Mhamon 1) what is your Qt version ? 2) How have you installed Qt? 3) what is your OS?

Thanks to all.
Solved - reinstalled qt and work fine.
