const net = require("net");

const port = 5000;

const server = net.createServer((socket) => {
    console.log("Client connected");

    socket.on("data", (data) => {
        const strData = data.toString();
        console.log(`Received: ${strData}`);

        const command = strData.split(",");
        const operator = command[0];
        const operand1 = parseFloat(command[1]);
        const operand2 = parseFloat(command[2]);
        let result;

        switch (operator) {
            case "add":
                result = operand1 + operand2;
                break;

        }

        socket.write(result.toString());

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

app.get('/', (req, res) => {
  // Ran when a GET request to path '/'
  res.sendFile(__dirname + '/index.html');
});

io.on('connection', (socket) => {
  // Ran when a socket connected
});

http.listen(3000, () => {
  // Ran when server is ready to take requestes
});
