Getting started with Facebook Connect & News Feed

Facebook connect has been one of those things that I’ve been tinkering with for a while now. I started by downloading the example Facebook connect application from Facebook. and gradually found my way around using it. Im using the same authentication methods as Noah Hendrix’s did over at Nettuts, but extending this method to include updating a users newsfeed.

So to get started you need to head over to Facebook and create a new application

Below are the steps to setting up an application on Facebook.

Firstly navigate to the Facebook developer homepage to register your application


Choose a name for your app and agree to the Terms


Your application key along with your secret is displayed on the next page


Click connect in the menu to add the URL to which your application will be hosted


You now need to put your API key in here.


The complete Facebook connect demo code is below. Lets take a look at it. In this example we’re simply authenticating a facebook user with javascript and posting their comment to the users news feed using the API. We also need to include a cross domain receiver file which allows us to transfer data between our domain and Facebook platform. If the user is authenticated we pull in their name, avatar, and profile url, and hide the name input field and facebook connect login button. Now when the user submits a comment (after the javascript alert which is there for demo purposes) they are given the option to post the comment to their newsfeed. Check out the video from the facebook connect developers below which explains how to setup the json code to dynamically update their newsfeed.
