Trying to use session data in socket resulting to "undefined". '

(app.js)

const express = require("express"); const express_validator = require("express-validator"); const path = require("path"); const body_parser = require("body-parser"); const nunjucks = require("nunjucks"); const socket = require("socket.io"); const mysql = require("mysql"); const cookieParser = require("cookie-parser"); const session = require("express-session")({ resave: true, saveUninitialized: true, secret: "Test" });

//Main application var app = express(); var server = app.listen(3000, () => { console.log("Server is started.."); });

//Static configuration app.use(express.static("public"));

//View configuration nunjucks.configure("views", { express: app, watch: true, autoescape: true }); app.set("views", path.join(__dirname, "views")); app.set("view engine", "nunjucks");

//Middlewares app.use(express_validator()); app.use(body_parser.json()); app.use(body_parser.urlencoded({extended: false})); app.use(cookieParser()); app.use(session);

var sharedsession = require("express-socket.io-session");

var socket_handler = require("./socket.io/socket")(io);

(socket.js)

module.exports = function(io) { io.sockets.on("connection", (socket) => { console.log(socket.handshake.session.username) //Username is set when logging in } }

(index.js) //Route handler
