how to send json as a response after passport authenticationin node.js

Question

I am trying this git example.

Which works well when I integrated it with my project, but what I want to achieve is to send json as a response to the client/request,

Answer 1

here I modified my code to send json as a response

// process the signup form
app.post('/signup', passport.authenticate('local-signup', {
    successRedirect : '/successjson', // redirect to the secure profile section
    failureRedirect : '/failurejson', // redirect back to the signup page if there is an error
    failureFlash : true // allow flash messages
}));

app.get('/successjson', function(req, res) {
    res.sendfile('public/index.htm');
});

app.get('/failurejson', function(req, res) {
    res.json({ message: 'hello' });
});
