Feras,
My point is that you'll find your application easy to manage if you keep
your login code (authenticate) separate from your presentation code
(JQuery). See below for an (untested) example based on your original code:
It'll also help you if you explain what exactly is happening that you don't
expect. If you just say it "isn't working" then its much harder to for us
to help.
Good luck!
// Server JS
app.get('/', function(req, res, next) {
passport.authenticate('local', function(err, user, info) {
if (err) return next(err);
if (!user) return res.send(401);
// Not sure what the difference between authenticate and logIn is
in this context. Persistence maybe?
req.logIn(user, function(err) {
if (err) return next(err);
return res.send(200);
});
})(req, res, next);
});
// Client JS
$.get("/")
.failure(function(){
$("#error")
.text("YOUR MESSAGE")
.show()
.delay(800)
.fadeOut(400);
})
.success(function(){
document.location.href = "/account"
})
