Coffeeshop screencast: HTTP conneg, resource representations and JSON

After yesterday’s screencast showing the use of coffeeshop from the command line, here’s one that expands upon the direction I’m taking the implementation, following the REST/HTTP philosophy. It shows, I hope, that embracing REST-orientated HTTP features, such as content negotiation (“conneg”), and the concepts of resources and representations, gives you a fantastically flexible and straightforward application protocol to work with and be guided by. (I’m not doing full-blown conneg, that will come later. But what I am doing works well for me).

In this shorter screencast, I continue on from where I left off — viewing the message detail resource in the web browser. I use conneg to request that same resource in JSON instead of HTML, and show how the JSON representation can be easily parsed, and the data reused, further along the pipeline.
