En başta istemci bacağında nasıl bir js dosyası çalışacak:
$(document).ready(function () {
// connect to the socket server
var socket = io.connect();
// if we get an "info" emit from the socket server then console.log the data we recive
socket.on('info', function (data) {
console.log("info client tarafı");
console.log(data);
});
});app.js içindeki kritik nokta:
/* SESSION Ayarları */
var session = require('express-session');
var RedisStore = require('connect-redis')(session); // Redis'te tutacağız
