ColdFusion 8 is beautiful. Without question untouchable. During lunch today I threw together a crude but effective proof of concept feed reader in 45 minutes and with around 55 lines of code. 55. You heard me right. A dynamic Ajaxified feed reader. If you subtract the html tags it's probably more like 40 lines.

I've got a demo hosted up at HostMySite.

Let me break down a few of the new bits to show how some of it is done in CF8. The complete example is attached as a zip to this post.

First cool thing is the cflayout with a type of 'border'. This layout gives us a cool bordered layout in which we can use different cflayoutarea's (top, left, bottom, etc) to get a nice structured feel to our application.

So I've got a border layout here with a left panel and a main content panel (position="center"). In the left panel I simply output a dynamic spry dataset of feeds (of course created with cfsprydataset). In the main content area I'm binding the layoutarea to the url 'feed.cfm'. By default I'm not displaying anything - but I could have easily displayed a "Please choose a feed message" by checking to see if my url variable was passed.

So in my feed list I'm calling getFeed() and passing the url in my dataset. Here's a look at my getFeed() function.

More easiness. I use the built in ColdFusion.navigate() function to load the feed from feed.cfm and return the contents of that page to the 'feedContainer' (which is the name of my cflayoutarea).

What about feed.cfm? Must be a complicated template right? Wrong. Without showing every bit of display code - here's the heart of the page:

Using cffeed gets the contents of the feed and returns the items as a query (by specifying the query attribute) as well as a struct of metadata (by specifying the properties attribute). A bit of outputting this data in some div's and that is it.
