How to create session cookies with Node.js + Express

nodejs-express-cookies-example.js

var     express = require('express'),
        app = express(),
        https = require('https'),
        fs = require('fs'),
        keys = require( "keygrip" )(['secret1', 'secret2']),
        cookies = require( "cookies" );

// This line is from the Node.js HTTPS documentation
var options = {
  key: fs.readFileSync('private_key_cert.pem'),
  cert: fs.readFileSync('public_cert.pem')
};

app.use(cookies.express(keys));

app.get('/', function(req, res){
  if (req.cookies.remember) {
    res.send('Remembered :). Click to <a href="/forget">forget</a>!.');
  } else {
    res.send('<form method="post"><p>Check to <label>'
      + '<input type="checkbox" name="remember"/> remember me</label> '
      + '<input type="submit" value="Submit"/>.</p></form>');
  }
});

app.get('/forget', function(req, res){
  res.clearCookie('remember');
  res.redirect('back');
});

app.post('/', function(req, res){
  var minute = 60 * 1000;
  if (req.body.remember) res.cookie('remember', 1, { maxAge: minute });
  res.redirect('back');
});

// Create an HTTPS service
https.createServer(options, app).listen(443);

console.log('Express started on port %d', 443);
