html5 offline application

2 days ago I’ve lost my internet connection at home. But I had very important emails for me on the gmail. But I thought I have offline application for gmail developed by google.

I’ve installed this chrome app just for checking possible implementation for offline apps. because on my current work we are working on the creation with the same functionnality application. Offline gmail is using web sqlite storage for saving cached / synced data.

it looks like

Time to completely client side applications. Yeah, it’s really awesome. But for less complex applications it’s pretty simple to use localStorage for saving synced data.

Also as I see guys in google added syncing process on the background and refresh button for manually syncing by user action. 

For opening application they are using html5 application manifest for caching resources like css/js/images. In Rails we are using rack-offline for generating same manifest file choosing files for caching.
