Modulus has a good beginner's guide to node.js. They are also "a premier Node.js hosting platform that provides a complete technology stack for application developers. This includes custom SSL, WebSockets, MongoDB, statistics, and more. Signup is quick and free" (from the 'About' box on the web page: http://blog.modulus.io/absolute-beginners-guide-to-nodejs

I've used node.js for cross-domain file retrieval and, although a it is a little arcane, it is relatively easy to get running.

Not sure if you still need this but here we go:
The code snippet bellow just retrieve Google's web page. It's trivial and self-explanatory. If you need more explanations, feel free to ask.

var http = require('http'),
 options = { 
  host: 'www.google.com',
  port: 80,
  path: "/",
  method: "GET",
  headers:{
    "Host" : 'www.google.com',
    "User-Agent" :	'Nodejs',
  }
};
	  
var request = http.request(options, function(res) {
       // console.log('STATUS:', res.statusCode);
       // console.log('HEADERS:', res.headers);
        res.setEncoding('utf8');
        res.on('data', function (chunk) { console.log('BODY:', chunk); });
   }).end();

Copy past the code above in let's say a get.js file then at your command line run it as follow:

node get.js

All the data will be dumped at your console. If you also want to see the sent headers comment out the adhoc line in the code.

Note: Of course you must have Node.js installed for this to work.

Good luck.

Lately I have started using JavaScript Web stack : MEAN. MongoDB, ExpressJS, AngularJS, and NodeJS, for web app development.

I'm following this tutorial to create RESTful API: https://scotch.io/tutorials/build-a-restful-api-using-node-and-express-4

Angular JS is awesome MVC framework for build single page apps.
