Offline.js is a library to automatically alert your users when they've lost internet connectivity, like Gmail.
It captures AJAX requests which were made while the connection was down, and remakes them when it's back up, so your app reacts perfectly.
It has a number of beautiful themes and requires no configuration.
The easiest way to add Offline to your site is with Eager.
