I’m happy to share the code from a Facebook app I created for a workshop earlier this year.
This is an example of a simple Facebook canvas application. This code was originally demoed during the Freedom for Our Files Facebook API workshop at the 2011 Art Meets Radical Openness festival in Linz, Austria. You can view and download the source code on github
The application is very simple; it creates a Facebook object, performs calls to get data belonging to the current user, then prints the data exactly as it is returned. It has examples of basic Facebook Graph API calls as well as an example of FQL (Facebook Query Language).
