There has been many ideas about a offline storage mechanism for web applications. Dojo implemented this<\/a> in its Library. Firefox 3 promises this<\/a>. Now we have a new arrival in this area – Google Gears<\/a>. Unlike Dojo’s implementation, Gears require an extension for it to work.<\/p>\n

Google Gears is an open source browser extension that lets developers create web applications that can run offline.<\/p>\n<\/blockquote>\n

To see Gears in action, first install the extension…<\/p>\n

Then go to Google Reader – you will see a ‘Offline’ mode button in the top right corner. If you click on that the script will download 2000 entries into your local database(SQLite<\/a>).<\/p>\n

Downloading Online Entries using Google Gears<\/p>\n

To see this database, open up the Firefox Profile folder<\/a> and enter the ‘Google Gears for Firefox’ folder. You will find many Database files there. Just open any of these in a SQLite V3 supporting viewer.<\/p>\n

After the download is complete, you can use the Reader without a net connection.<\/p>\n

When you get the connection back, just click on the same button – all the changes will be send to the online server.<\/p>\n
