Google has released a new beta product called “Google Gears” which looks to be a really slick JavaScript API that will allow you to take dynamic website applications and give them an off line instance. This way users can work in a disconnected state and then, when back online, resynchronize their data.

Gears contains three components:


Cache and serve application resources (HTML, JavaScript, images, etc.) locally


Store data locally in a fully-searchable relational database


Make your web applications more responsive by performing resource-intensive operations asynchronously

The offline version is updated automatically everytime a user reconnects so long as the online versions “manifest.json” file has it’s version number properly incremented.

Overall it looks really slick and I can’t wait to dig into it a bit. You can check it out at
