Using socket.io in modules and routes Express - node.js

Question

I am having some issues using socket.io is modules. I have changed the way I do it quite drastically, however everything seems to be working, except being able to send userdata back to my socket connection:
Here is my io.js file: /config/io
/*jshint esversion: 6*/
var io = require('socket.io')();
const moment = require('moment');
// Socket stuff
io.on('connection', function (socket) {
socket.on('login', function (userdata) {
socket.handshake.session.userdata = userdata;
socket.handshake.session.save();
console.log(socket.handshake.session.userdata);
});
// Server Time
var interval = setInterval(function () {
var momentNow = moment();
var data = momentNow.format('LT');
socket.emit('time', data);
}, 60000);
// Chat - Needs work
socket.on('chat', function (msg) {
console.log(msg);
var username = 'Message'; //socket.handshake.session.userdata.username;
var message = '[' + moment().format('LT') + '] ' + username + ': ' + msg;
io.emit('message', message, username);
});
socket.on('disconnect', function () {
if (socket.handshake.session.userdata) {
delete socket.handshake.session.userdata;
socket.handshake.session.save();
}
console.log('user disconnected');
});
});
module.exports = io;
Here is where I'm trying to emit the data /config/passport: (please note that userdata does indeed contain the right information!)
/*jshint esversion: 6 */
const LocalStrategy = require('passport-local').Strategy;
const db = require('../config/db');
const bcrypt = require('bcryptjs');
var io = require('./io');
module.exports = function(passport) {
// Local Strategy login
passport.use(new LocalStrategy(function(username, password, done) {
// Match Username
let sql = 'SELECT * FROM users WHERE username = ?';
db.query(sql, [username], function(err, rows) {
if (err)
return done(err);
if (!rows.length) {
return done(null, false, {
type: 'loginMessage',
message: 'Wrong Login',
});
}
// Match Password
bcrypt.compare(password, rows[0].password, function(err, isMatch) {
if (err)
return done(err);
if (isMatch) {
var userdata = rows[0];
io.emit('login', userdata); // HERE IS WHERE I TRY TO EMIT IT
// console.log(rows[0]);
return done(null, rows[0]);
} else {
return done(null, false, {
type: 'loginMessage',
message: 'Wrong Login',
});
}
});
});
}));
Now here is my main app file: (leaving out a bunch of stuff)
var io = require('./config/io');
// Init App
const app = express();
// Init http server
const server = http.createServer(app);
// Attach IO
io.attach(server);
// Listen
server.listen(8080, function () {
console.log('Server listening on port 8080...');
});
Now, everything seems to be working fine, except being able to emit the data. Now I tried logging it client side as well (just in case it was emitting on client-side and not server-side) but it is not doing that as well.

Okay, so here is an actual working answer. It s a work-around, and I completely abandoned trying to do it from the passport login handler itself. But here is how I did it:
IO code:
var session = socket.handshake.session;
socket.on('login', function () {
if (socket.handshake.session.passport === undefined) {
var destination = '/';
socket.emit('not logged', destination);
} else {
console.log('user logged in');
var userId = session.passport.user;
var sql = 'SELECT * FROM users WHERE id = ?';
var query = db.query(sql, userId, function (err, rows) {
session.userdata = rows[0];
session.save();
var dataObj = session.userdata;
socket.emit('sart up', dataObj);
});
}
});
And jQuery:
// Connection Successful
socket.on('connect', function () {
connected = true;
socket.emit('login');
});
socket.on('disconnect', function () {
connected = false;
});
socket.on('not logged', function (destination) {
window.location.href = destination;
});
socket.on('start up', function (dataObj) {
});
I'm not a huge fan of having to do it this way, I would have liked to handle everything sever-sided, but for now this is working, and will use until I figure out how to do it the way I'd like to.
