Posted 2021-05-03

var app = require('../app');
var http = require('http');

/**
 * Get port from environment and store in Express.
 */

var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);

/**
 * Create HTTP server.
 */

var server = http.createServer(app);

/**
 * Create Socket.IO server
 */
 
var io = require('socket.io')(server);

/**
 * Listen on provided port, on all network interfaces.
 */

server.listen(port);
