Build a page counter service in Node

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine, which enables you to run JavaScript code on the server. It has excellent support for modern JavaScript, using the latest and most modern syntax. It's fast and scalable.

An often-touted advantage of using JavaScript on a web server—as well as in the browser—is that your brain no longer needs to switch modes. You can do everything in the same language, which, as a developer, makes you more productive (and hopefully, happier).

In Chapter 2 of Your First Week With Node.js, you'll build your first Node app: a simple page counter service that can be used to display “this page has been viewed X times”, just like HTML developers did twenty years ago.

You'll start by builiding a counter that stores the number of views in memory, and then refine that counter to make use of file storage so that the view count is not lost when he Node application is restarted. Along the way you'll discover how to initialize a Node application and get an introduction to some of Node's commonly used modules.
