Redirecting POST to GET after Database Addition - node.js

Question

I am using Mongoose and Express.js .
My Post request looks like this :
$('#update').on('click', function() {
var uname = $('#username').val();
var name = $('#name').val();
var json = {
user_name: name,
user_username: uname,
};
$.post("/saveprofile", json, function(data, error, xhr) {
if(!err)
window.location.href = "/feed";
});
});
This is how I'm handling the request :
app.post('/saveprofile', isLoggedIn, function(req, res) {
var username = req.body.user_username;
var uname = req.body.user_name;
User.findOne({$or:[{"facebook.email":req.user.facebook.email},{"local.email":req.user.local.email}]}, function (err, user){
user.name = uname;
user.username=username;
user.save();
res.send({redirect: '/feed'});
})
});
My documents get added into the db successfully but what I want is, when that happens it should redirect to a new page /feed . The above snippets mention 2 methods I've tried. But I've got no result . It doesn't redirect !
Edit:
Testing with exception handling gives undefined
app.post('/saveprofile', isLoggedIn, function(req, res) {
var username = req.body.user_username;
var uname = req.body.user_name;
try{
User.findOne({$or:[{"facebook.email":req.user.facebook.email},{"local.email":req.user.local.email}]}, function (err, user){
user.name = uname;
user.username=username;
user.save();
res.redirect("http://stackoverflow.com")
});
}
catch(ex){
console.log(ex) ;
}
});
Edit 2 :
I tried a sample request ...even it doesn't seem to redirect !
app.post('/test', isLoggedIn, function(req,res){
res.redirect("http://www.stackoverflow.com")
})

Answer 1

You can't make a redirection after an AJAX. You need to do it with Javascript.
So here is how we can do it,
Post request :
$('#update').on('click', function() {
var uname = $('#username').val();
var name = $('#name').val();
var json = {
user_name: name,
user_username: uname,
};
$.post("/saveprofile", json, function(data, err, xhr) {
if(!err)
window.location.href = data.redirect;
});
});
Server
app.post('/saveprofile', isLoggedIn, function(req, res) {
var username = req.body.user_username;
var uname = req.body.user_name;
User.findOne({$or:[{"facebook.email":req.user.facebook.email},{"local.email":req.user.local.email}]}, function (err, user){
user.name = uname;
user.username=username;
user.save(function(err){
if(!err)
res.send({redirect: '/feed'});
});
})
});

Try res.redirect() instead :
res.redirect("/feed");
