Get data from mongo while post request in node?

I have a simple POST request with sending mail by nodemailer.

app.post("/sendMail", function(req, res) {
    nodemailer.sendMail({ from: 'xx', to: userEmail }, function(error, info) {
        if (error) {
            return res.send(500, 'Internal error, try again later');
        }

        res.send(200, 'Mail sent!');
    });
});

However, for security reasons, Im not storing user mail anywhere in client-side. But in the request, I have user id.

Single collection in db looks like:

{
   id: '1312feew3',
   email: '[email protected]',
}

So if my req.body.id equals to 1312feew3, I need to get that specified collection and take the email out from it

What I tried

I tried to do simple:

var userEmail = getUserById(req.body.id, function (err, user) {
    if (err) {
        return res.send(400, 'Something went wrong');
    }
    return res.json(user);
}).email;

(I placed it on the second line in the first code)

Unfortunately it didnt work as I expected.

It doesnt throw any errors, however the mail is not being sent.

Assuming that getUserById is async, it can't return the user directly and you have to access it from within the callback function:

getUserById(req.body.id, function (err, user) {
    if (err) {
        return res.send(400, 'Something went wrong');
    }

    var userEmail = user.email;

    // Send the email here, within the callback as well.
    ...

    return res.json(user);
});
