Note: I had issues with setting up my Facebook app so authentication would work. I'd receive the error at the bottom, and it took me a while to figure out what was wrong
Here are the steps I took:
- Go to
http://developers.facebook.com/
, create, and setup your app - When inside the dashboard, click "Settings"
- Click "Add Platform"
- Choose website (for authentication via the web app)
- Add
http://localhost:3000/
as "Site URL" (and "Mobile URL" if necessary) - Add
localhost
to "App Domains" above
