Node js JQuery Ajax json_encode equivalent

Question

So, I have a JQuery Ajax client side. But now I want to handle the ajax post Node.js side.

I have my route and body parser.

app.post('/register', function(req, res){
    var firstname           = req.body.firstname;
    var lastname            = req.body.lastname;
    var email               = req.body.email;
    var password            = req.body.password;
    var confirm_password    = req.body.confirm_password;

    // Save into my database

         ...

    // Ajax callback return ???
});

In PHP I used json_encode($array) to get an ajax callback success. But how can I do that in node.js ?

Thanks for your answer, but with that I don't have any return. I set console.log('AJAX OK') inside my route and it works but the JSON.stringify returns me nothing — John

JSON.stringify returns json, just like json_encode does in PHP. It doesn't output anything. Are you asking how to send the json response? It looks like you're using express, so take a look at the docs for the Response. You could use: res.json( array );. — Paul

You're welcome. I made my comment into an answer since it seems to be the answer to your question anyway. — Paul

It looks you're using express and want to send a JSON response. You can use res.json for that.
