express session example:

var express = require('express'); var session = require('express-session'); var app = express();  // make sure defined before of routes // make use of session. app.use(session({   secret: 'keyboard cat',    cookie: { maxage: 60000 },   resave: false,   saveuninitialized: false }));  // access session req.session app.get('/login', function(req, res) {   req.session.user = 1;   res.end('user 1 logged in, please go /discussion page.'); });  app.get('/discussion', function(req, res) {   var sess = req.session;   if (typeof sess.user === 'undefined') {      res.redirect('/login');   } else {     res.setheader('content-type', 'text/html');     res.write('<p>user: ' + sess.user + '</p>');     res.write('<p>expires in: ' + (sess.cookie.maxage / 1000) + 's</p>');     res.end();   } });
