Facebook JS SDK, tracked and de-minified

This project aims to provide a useful resource to developers who are working with Facebook's JS SDK and would like to see what has changed recently.

My server runs a cronjob every 10 minutes that downloads the latest, commits any changes, and then pushes to github.

(debug.js is the non-minified version of that you're probably using in production.)

The script does not commit if only the timestamp at the top has changed.


To run your own copy (which I recommend), you'll need to fork the github project, test the shell script, and then set up cronjob like so:

# m h dom mon dow command
0 5 * * * /home/nfriedly/facebook/connect-js/ > /dev/null

This setup sends an email if there were errors, but not if everything worked successfully.

Setup on Heroku

This script works well on a free Heroku instance. Put your github username and password (or token) in environmental variables like so:

heroku config:add GH_USER=<username>
heroku config:add GH_PASS=<password>

Then add the Heroku Scheduler addon and create a task that runs ./ as often as you'd like.

To Do

  • Track individual components (init.js, json.js, xfbml.js, etc)
  • Keep a copy of the minified file in addition to debug.js
  • Track the xdm.swf file
  • Track the beta js
  • Figure out how to get error notifications if the heroku process fails
