javascript node socket.io too much requests

Hello guys i have simple example with sockets:

const app = express();  const server = require("http").createServer(app);  const io = require("socket.io")(server, {    cors: {      origin: "http://localhost:3000",      methods: ["GET", "POST"],      credentials: true    }  });    var userCount = 0;  io.on('connection', function (socket) {    userCount++;    io.emit('userCount', { userCount: userCount });      socket.on('disconnect', function() {      userCount--;      io.emit('userCount', { userCount: userCount });    });    });  

and frontend:

  const [userCount, setuserCount] = useState(0);    socket.on('userCount', function (data) {      setuserCount(data.userCount);    });  

I dont understand, but it fire so much requests .. And my question is this proper way to work with sockets?
