Enabling HTTPS on express.js

I'm trying to get HTTPS working on express.js for node, and I can't figure it out.

This is my app.js code.

var express = require('express');
var fs = require('fs');

var privateKey = fs.readFileSync('sslcert/server.key');
var certificate = fs.readFileSync('sslcert/server.crt');

var credentials = {key: privateKey, cert: certificate};


var app = express.createServer(credentials);

app.get('/', function(req,res) {
    res.send('hello');
});

app.listen(8000);

When I run it, it seems to only respond to HTTP requests.

I wrote simple vanilla node.js based HTTPS app:

var   fs = require("fs"),
      http = require("https");

var privateKey = fs.readFileSync('sslcert/server.key').toString();
var certificate = fs.readFileSync('sslcert/server.crt').toString();

var credentials = {key: privateKey, cert: certificate};

var server = http.createServer(credentials,function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello Worldn');
});

server.listen(8000);

And when I run this app, it does respond to HTTPS requests. Note that I don't think the toString() on the fs result matters, as I've used combinations of both and still no es bueno.

EDIT TO ADD:

For production systems, you're probably better off using Nginx or HAProxy to proxy requests to your nodejs app. You can setup nginx to handle the ssl requests and just speak http to your node app.js.

EDIT TO ADD (4/6/2015)

For systems on using AWS, you are better off using EC2 Elastic Load Balancers to handle SSL Termination, and allow regular HTTP traffic to your EC2 web servers. For further security, setup your security group such that only the ELB is allowed to send HTTP traffic to the EC2 instances, which will prevent external unencrypted HTTP traffic from hitting your machines.

In express.js (since version 3) you should use that syntax:

var fs = require('fs');
var http = require('http');
var https = require('https');
var privateKey  = fs.readFileSync('sslcert/server.key', 'utf8');
var certificate = fs.readFileSync('sslcert/server.crt', 'utf8');

var credentials = {key: privateKey, cert: certificate};
var express = require('express');
var app = express();

// your express configuration here

var httpServer = http.createServer(app);
var httpsServer = https.createServer(credentials, app);

httpServer.listen(8080);
httpsServer.listen(8443);

In that way you provide express middleware to the native http/https server

If you want your app running on ports below 1024, you will need to use sudo command (not recommended) or use a reverse proxy (eg nginx, haproxy).

I ran into a similar issue with getting SSL to work on a port other than port 443. In my case I had a bundle certificate as well as a certificate and a key. The bundle certificate is a file that holds multiple certificates, node requires that you break those certificates into separate elements of an array.

    var express = require('express');
    var https = require('https');
    var fs = require('fs');

    var options = {
      ca: [fs.readFileSync(PATH_TO_BUNDLE_CERT_1), fs.readFileSync(PATH_TO_BUNDLE_CERT_2)],
      cert: fs.readFileSync(PATH_TO_CERT),
      key: fs.readFileSync(PATH_TO_KEY)
    };

    app = express()

    app.get('/', function(req,res) {
        res.send('hello');
    });

    var server = https.createServer(options, app);

    server.listen(8001, function(){
        console.log("server running at https://IP_ADDRESS:8001/")
    });

In app.js you need to specify https and create the server accordingly. Also, make sure that the port you're trying to use is actually allowing inbound traffic.

This is how its working for me. The redirection used will redirect all the normal http as well.

const express = require('express');
const bodyParser = require('body-parser');
const path = require('path');
const http = require('http');
const app = express();
var request = require('request');
//For https
const https = require('https');
var fs = require('fs');
var options = {
  key: fs.readFileSync('certificates/private.key'),
  cert: fs.readFileSync('certificates/certificate.crt'),
  ca: fs.readFileSync('certificates/ca_bundle.crt')
};

// API file for interacting with MongoDB
const api = require('./server/routes/api');

// Parsers
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

// Angular DIST output folder
app.use(express.static(path.join(__dirname, 'dist')));

// API location
app.use('/api', api);

// Send all other requests to the Angular app
app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, 'dist/index.html'));
});
app.use(function(req,resp,next){
  if (req.headers['x-forwarded-proto'] == 'http') {
      return resp.redirect(301, 'https://' + req.headers.host + '/');
  } else {
      return next();
  }
});


http.createServer(app).listen(80)
https.createServer(options, app).listen(443);
