[NodeJS + MongoDB] Mongoose/BodyParser not correctly accepting urlencoded POST requests

item.js

var mongoose = require('mongoose');

//Defining a schema for database entries.
var itemSchema = new mongoose.Schema({
   name: String,
   quantity: Number
});

//Exporting the model (containing the schema) to use as a module in other files
module.exports = mongoose.model('Item', itemSchema);

server.js

var express = require('express');
var mongoose = require('mongoose');
var bodyParser = require('body-parser');
var Item = require('./item');

//Express Application is the main component of the web app.
//Used to define routes, listen on http connections, perform routing for requests, and more
var app = express();

//Enable the body-parser package for use in our application
app.use(bodyParser.urlencoded({
    extended:true}));
app.use(bodyParser.json());

var dbUrl = "mongodb://localhost:27017/testdatabase";
var port = 3000;

//Connecting to the Mongo Database
var connection = mongoose.connect(dbUrl);


//Router are similar to "mini applications" - capable only of middleware and routing
//Every express application has a built in app router.
//Routers behave like middleware and can be .use()'d by the app or in other routers
var router = express.Router();

router.use(function(req, res, next){
   console.log("Request Made");
   next();
});

//Creating a route for '/' to return a JSON object
router.get('/', function(req, res) {
    res.json({ message: "response!" })
});

//Creates a new route within the already created router for '/'
var itemRouter = router.route('/items');

//Creating an endpoint for POSTS /api/beers
itemRouter.post(function(req, res){
    console.log(req.body);
    var newItem = new Item();
    newItem.name = req.body.name;
    newItem.quantity = req.body.name;
    //Code below works with JSON formatted inputs.
    //newItem.quantity = req.body[1].value;
    //newItem.quantity = req.body[1].value;

    //Saves the new item to the database
    newItem.save(function(err){
        if(err) {
            res.send(err);
        }
        //sends a response

        res.json({
            message: 'Item added to the database!',
            data: newItem
        });
    });
});

//Creating the endpoint for GET requests on '/api/items'
itemRouter.get(function(req, res){
   item.find(function(err, items) {
       if(err){
           res.send(err);
       }
       res.json(items);
   });
});

//Creating a new route to add items to our
//Register all previously defined routes with the prefix '/api'
app.use('/api', router);


app.listen(port);
