node.js

Whether you are building social platform or a simple website, sometimes you need to let users upload their own files. The typical scenario might be: uploading the user's photo for a profile page. With Node.js and express it is quite easy to create your own file upload service. In this post I will show you how. In the new folder run `npm init`, and create `package.json` as you usually do for every fresh Node project.

REST services became a de-facto standard of data exchange for public APIs. Twitter, GitHub, Parse are just few examples that rely on REST to exchange data with the clients. Before we start to write our first REST service with Node, let's see what exactly is REST and how it works. REST stands for 'REpresentational State Transfer'. It leverages the semantics of HTTP protocol to express operations over a some collection of items (data). REST typically uses JSON to send and receive data. NOTE: This is a common misconception to call every HTTP-based JSON service REST.
