Passport Authentication immediately after New User Registration

Here's the solution I came up with after reading about req.login:

app.post('/register', function(req, res) {
  // attach POST to user schema
  var user = new User({ email: req.body.email, password: req.body.password, name: req.body.name });
  // save in Mongo
  user.save(function(err) {
    if(err) {
      console.log(err);
    } else {
      console.log('user: ' + user.email + " saved.");
      req.login(user, function(err) {
        if (err) {
          console.log(err);
        }
        return res.redirect('/dashboard');
      });
    }
  });
});

I would like to clean it up a bit and think that the err section could be more robust, but this is a functioning solution. Note that is someone else implements this, they should be aware that it is tailored to using the passport-local strategy with email instead of username.
