Before write this i tried the solution at Using socket.io in Express 4 and express-generator's /bin/www
The terminal show an error on /routes/messages.js:12
io.on('connection', function(socket){
TypeError: Cannot read property 'on' of undefined
Here comes my files:
/routes/messages.js
var express = require('express');
var controller = require('../controllers/messageController');
var passport = require('passport');
var router = express.Router();
router.get('/', controller.plain);
module.exports = function(io){
var router = express.Router();
io.on('connection', function(socket){
console.log('**********************************************************');
console.log('mensaje desde socket.io en el archivo de rutas messages.js');
console.log('**********************************************************');
});
return router;
};
