We want to enable you to build complete web apps in days, without having to worry about backends, databases or servers, all with an open-source library that's as simple to use as jQuery. That's why we're making Hoodie. Hoodie is a noBackend architecture for frontend-only web apps.

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.
