Starting Skeleton, Template, For Sqlite Google Gear Self-Contained Client Apps

Client side applications using google gears for locally storing SQL data are obviously the future. They allow applications to be run on any operating system without coding user interfaces, learning new languages, or managing SQL database daemons/servers. You can start by running the application off a server. But it’s much better to simply download the web page and run it disconnected from the internet. To start the application in the future you simply click on the html file you downloaded.¬† It is so cool.

Where are all the example sites describing how to use google gears for client side applications though? I’ve looked for starting point skeletons and have found NONE! I believe it is because the subject is new. So I’m publishing my own skeleton. It can be found at http://ioconnor.atbhost.net/google.gears.skeleton.html. I’ll probably upgrade it as time goes on but my skeleton is quite good already. After you read through Google’s tutorials at http://code.google.com/apis/gears/tutorial.html download my code and use it as a starting point for your own project. Don’t reinvent the wheel!

My skeleton is self-contained. There’s no need to download a set of files or update a registry, run an installation script, etc., assuming your environment is complete.

However if your base environment is not complete no problem. The environment is tested to verify the gears addon has already been installed, that javascript is enabled, and that you have an up-to-date browser. If something is lacking you must click “ok” to acknowledge the problem and then your browser takes you to the URL where¬† the fix is.

I wish I had this easy to use skeleton a long time ago. It makes client side browser applications using SQL easy!

I’m probably going to make quite a few client side browser applications using this template. Having a free interface, sql database, and programming language across all OS platforms levels the playing field so much it can’t be ignored.

Update 2009.04.08: The code was refined yet again tonight. There’s nothing in it that seems to be lacking that can be done better. However please comment on it if there is something more that could be done…
