How to pass client-side parameters to the server-side in Angular/Node.js/Express

Question

Probably a very basic question, but I cannot seem to find a simple answer.

I have a GET method leveraging Angular\'s $http that is requesting a promise

You can create a JS object with your parameters, and then use jQuery's $.param (http://api.jquery.com/jquery.param/) to easily serialize them into a URL query string:

var parameters = {
   amount: 123,
   description: 'test'
};

And on your $http call:

$http.get('URL_OF_INTEREST'+'?'+$.param(parameters))
        .success(
            function(success){
                console.log(success)
            })
        .error(
            function(error){
                console.log(error)
            });

EDIT: OR if you don't want to use jQuery:

$http.get('URL_OF_INTEREST', { params: parameters })
        .success(
            function(success){
                console.log(success)
            })
        .error(
            function(error){
                console.log(error)
            });

On server-side, just use the req object to get the parameters:

var amount = req.query.amount;
var description = req.query.description;
