It's time to build our very own Facebook Friends' Birthday Reminder app folks!
In the previous chapter, we saw how to consume a REST web service and display the data that we received from a web service using a factory. We learned about promises and why they are important while making asynchronous calls via factories.
Building on this, we will now see how to build an app that will consume Facebook's open graph, Application Programming Interface (API), to display your friends' upcoming birthdays.
We will also be learning about AngularJS directives, and build our very first directive to implement Facebook's authentication.
Before you proceed, make sure you are comfortable with the following features of AngularJS:
Routes
Controllers and Partials
The concept of promise
You are also going to need to have a Facebook account with some friends in it who have agreed to share information with your app
