Answer 1

You have to use the express.urlencoded() and express.json() middleware in order to parse body data that was sent via HTTP DELETE / POST / PUT .

After that, there will be a body property on the req object and you can use it like that:

this.handleSignup = function(req, res, next) {
    "use strict";

    var data = req.body,
        email = data.confirmEmail,
        // etc.
};

Answer 2

from the success response in your http post you could just assign a scope to it then display it to your partials. Something like this.

$http.post('/register', $scope.form).
  success(function(data) {
    $scope.data = data;
  });

Then from your partials/view

<div>{{data}}</div>
