facebook.jade

doctype html html(lang='en') body a(href='/auth/facebook') facebook app 

thanks in advance!

if want log successful login put in app.js route home:

router.get('/home', isauthenticated, function(req, res, next) {   console.log('get /home login success [%s]', req.user.username);   res.render('home'); }); 

if want greet person on home page username...

somewhere in app.js since you're using router:

var isauthenticated = function (req, res, next) {   // if user authenticated in session, call next() call next request handler    // passport adds method request object. middleware allowed add properties   // request , response objects   if (req.isauthenticated())     return next();   // if user not authenticated redirect him login page   res.redirect('/login'); }  router.get('/home', isauthenticated, function(req, res, next) {   console.log('get /home login success [%s]', req.user.username);   res.render('home', { user: req.user }); }); 

and in home.jade file:

//- incoming param(s): user doctype html html(lang='en') body   #{user.username} 

note use of isauthenticated in router. use force private content seen after authentication. if have bookmarked /home on website , want revisit next day they'll forced re-authenticate.
