Addressbook History goes into the cloud with App Engine

Ajax, JavaScript, Python, Tech with tags: Add comments

I recently built an example of the Form History Pattern using an Addressbook case study.

I found myself talking about App Engine on the On Air tour, so I decided to change the example to not store the data locally with Gears, but instead to save it away into the cloud via App Engine.


Why did people want to hear about App Engine at an Adobe conference? I think that Jonathan Schwartz got it when he mentioned rich internet back-ends. As you build rich clients, you suddenly realise that the promised benefits of web services can kick into gear nicely.

Addressbook Services

Back to the sample. The architecture change was quite simple. Where I was doing a local DB save, I would call a back-end service such as /loadcontacts or /savecontact depending on the task.

You can view and download the full App Engine project code for this sample, and you can see it running live on App Engine

Check out the video below, or view the high quality version (recommended) to see the code walk through, and the various tools that App Engine gives you to develop, debug, and monitor your application running at a few thousand feet.

    Great tutorial! Two for one (App Engine & Javascript)

    Quick example sites like this are really helpful while I try and learn App Engine programming.

    Thank you :)
