This little AIR app is just a step above a basic rx-gen generated AIR application. It adds the ability to:

• Go from online mode to offline mode and back. When you are in offline mode the application saves all the records to local AIR SQLite database.

• Synchronize records when you are back online. When you go back online the application switches to AS3JSONHTTPServiceProvider and you can optionally synchronize all the data you modified/created/deleted while offline using Rx.changes.push().

• Undo/redo. You can perform undo/redo on all creates/updates and deletes in both online and offline mode.

To try this app out do the following:

ruby soup.rb

This will start up your Sinatra server on localhost:4567

Next, go to localhost:5984/_utils (this is your CouchDB admin URL) and create a database called “sinatra”.

Then start your Soup AIR client:

rake air:run

Create some records, etc to try it out. To go into off-line mode simply stop the sinatra server. You can keep creating records after you go off-line. To go back online, start the server again. To synchronize push “Synchronize” button and check out your CouchDB server to make sure all the new stuff made it there.
