I want to understand how facebook notifications work. When someone like your posts, comments, send message, etc, facebook sends a notification as soon as the event done. I want to know if there is any server side script or events fired when users hit like button, posts, send messages, etc. I need to know how to implement something like that using jquery and php to use on my wbsite.
Push notifications on Facebook are the alerts you receive when your phone is locked or when you aren't actively browsing Facebook. Think of a Facebook push notification as an alert that pushes through the closed app to make you aware of any Facebook activities that may interest you.
When you turn on notifications, you'll get updates each time that person or Page posts something shared with you.
No, Facebook doesn't let people track who views their profile. Third-party apps also can't provide this functionality. If you come across an app that claims to offer this ability, please report the app. Was this helpful?
If you comment on a post, post notifications will automatically be turned on. If you turn on notifications for a post, you'll get notified whenever someone comments on the post. You won't get notified when someone replies to a comment. Go to the post that you'd like to turn notifications on or off.
It's done using push events: http://en.wikipedia.org/wiki/Push_technology
