In this tutorial, we'll create a simple date of birth dropdown menu.

In my previous article I showed a tutorial on "Uploading data to Amazon S3 from Node.js". This is a good fist step to move your project to a cloud, but there's another important aspect that you have to consider. Your data. Luckily Amazon offers a range of services that supports the needs of many kinds of applications.

What can be simpler than uploading file to the server and saving it to hard drive, right? Open read stream, read bytes, open write stream, write bytes, done. Now let's explore the same question but from a high-load high-availability service perspective. You're designing new Instagram, where will you store the photos? Remember, at a bare minimum you need to make sure that a failure to a single node in a data center will not interrupt your service (you can't allow to lose those precious cat pictures that your users are uploading).

In this small project we'll see how to implement Facebook authentication for your Node app with a help of Passport.js. Facebook authentication might sound like a lot of work but with the help of Passport, it is a surprisingly easy task. To give you a good feeling about the volume of code that you're about to write: It is about 80 lines of JavaScript and couple more lines of HTML. Before we start let's see how our application will look like. This is a truely minimalistic app with two pages: a login page and a "secret" page that only authenticated users are allowed to see.
