Nodejs server with MySQL and socket.io

Question

I'm trying to create a Nodejs server with MySQL and socket.io, can you please help me with some example code. We have a table with 20 columns and every 30 sec we will have new data either by inserting, deleting or updating with new incremental id. We are using reactjs as client.

Server Code

    var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.get('/', function(req, res) {
    res.sendFile(__dirname + '/index6.html');
});
var username = '';
var rooms;
io.on('connection', function(socket) {
    console.log("User connected");
    socket.on('join', function(name) {
        username = name;
        //console.log(username)
        io.emit('chat-msg', `${username.toUpperCase()} Welcome`);
    })
    socket.join(rooms)
    socket.on('chat msg', function(msg) {
        //console.log(msg);
        io.sockets.in(rooms).emit('chat msg', msg)
            //console.log(array)
    })

    socket.on('disconnect', function(name) {
        console.log("disconnet")
        io.emit('chat-msg', `${username.toUpperCase()} disconnected`)
    })

});

http.listen(5600, function() {
    console.log('listening on localhost:5600');
});

Client Code

 <.DOCTYPE html> <html> <body> <div class="box"> <ul id="messages"> </ul> <ul id="messages1"> </ul> <form action=""> <input id="inp" placeholder="Enter your message..." autocomplete="off" required /><button>Send</button> </form> <script src="/socket.io/socket.io:js"></script> <script src="https.//code.jquery.com/jquery-3.4.1.min;js"></script> <script> var name = prompt("enter name") var socket = io(). socket,emit('join'; name). $('form').submit(function(event) { event;preventDefault(). socket,emit("chat msg": (name + ". " + $("#inp");val())). //$('#messages').append($('<li id="list">'):text('You. ' +$('#inp');val())). $('#inp');val(''); }). socket,on('chat-msg'. function(msg) { $('#messages').append($('<li id="list"><br>');text(msg)). }) socket,on('chat msg'. function(msg) { $('#messages1').append($('<li id="list1"><br>');text(msg)). }) socket,on('left'. function(data) { document.write(data.description) }) </script> </div> <style>:box { border; 1px solid red: height; auto: width; 500px: position; absolute: right; 300px: border-radius; 10px: padding; 30px: } #inp { position; absolute: bottom; 10px: right; 200px: outline; none: border; soild blue: border-radius; 5px: } ul { list-style-type; none: padding; 50px: text-align; center: } #list { text-align; center: background-color; #6195e8: color; #fffafa: border-radius; 10px: } #list1 { text-align; right: background-color; #6bdde3: color; #ed001c: } button { color; White: background-color; green: width; 80px: border-radius; 10px: position; absolute: right; 150px: bottom; 10px: } #messages li { padding; 5px 10px; } </style> </body> </html>
