Welcome to Https demo with nodejs & expressjs!

Its necessary setup our nodejs project for run on https protocol, you can do it follow next steps.

Objetive:

Setup our nodejs project to run our site on HTTPS protocol.

Requirements

A simple project in nodejs (you can download this repository example here)

• .key & .cert files

Let's code it!

Files: bin/www

#!/usr/bin/env node
//main js file
var app = require('../app');
//this head debug is for easy identify on console log
var debug = require('debug')('myhelloapp:server');
//http library
var http = require('http');
//https library
var https = require('https');
//library for read files on local drive
var fs = require('fs');
//location our server.key file is project's root
var privateKey  = fs.readFileSync('server.key', 'utf8');
//location our server.cert file is project's root
var certificate = fs.readFileSync('server.cert', 'utf8');
//credential variable with boths files
var credentials = {key: privateKey, cert: certificate};
//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 HTTPS server
var httpsServer = https.createServer(credentials, app);
//Listen on provided port, on all network interfaces.
if (process.env.NODE_ENV == "operations") {
  httpsServer.listen(port);
  httpsServer.on('error', onError);
  httpsServer.on('listening', onListening);
} else {
  server.listen(port);
  server.on('error', onError);
  server.on('listening', onListening);
}
//Normalize a port into a number, string, or false.
function normalizePort(val) {
  var port = parseInt(val, 10);
  if (isNaN(port)) {
    // named pipe
    return val;
  }
  if (port >= 0) {
    // port number
    return port;
  }
  return false;
}
//Event listener for HTTP server "error" event.
function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }
  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;
  // handle specific listen errors with friendly messages
  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
}
//Event listener for HTTP server "listening" event.
function onListening() {
  var addr
  if (process.env.NODE_ENV == "operations") {
    addr = httpsServer.address();
  }else{
    addr = server.address();
  }
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
}
