How to configure ssl on express - node.js

Question

I am trying to configure ssl in express with the following configuration but I keep on getting errors and I am not able to figure out how to solve this.
use strict';
//dependencies
var config = require('./config'),
//uuid = require('node-uuid'),
express = require('express'),
session = require('express-session'),
mongoStore = require('connect-mongo')(session),
http = require('http'),
path = require('path'),
passport = require('passport'),
mongoose = require('mongoose'),
helmet = require('helmet'),
https = require('https');
//create express app
var app = express();
//keep reference to config
app.config = config;
app.server = https.createServer(app.config.ssl_options, app);
//listen u
app.server.listen(443);
Here is how I am importing the config files, the config files are placed in config.js
exports.ssl_options = {
key: fs.readFileSync('./ssl.key'),
cert: fs.readFileSync('./2b62bb384fb2b9.crt'),
ca: fs.readFileSync('./gd_bundle-g2-g1.crt')
};
Here are my errors
events.js:72
throw er; // Unhandled 'error' event
^
Error: listen EACCES

The line that I am getting the errors is
//listen u
app.server.listen(443);

If you're binding to a port < 1024, you have to use sudo to start your server because only privileged users (root) can bind to those ports.
