Rich Client is a term thats been hanging around for a while now, it describes a group of applications that provide more client end functionality than traditional websites would.
Encompassed in this group are technologies and methodologies such as Flash, AJAX, XUL and XForms. It’s all about giving users more interactivity and providing an experience that would normally be associated with desktop client software.
Recently our Department was approached by a customer to produce a prototype vehicle dashboard for an offroad vehicle, it would be a browser based app which would take vehicle stats and display them for engineers to examine. Aha I thought, the perfect opportunity to try out Laszlo. I had a very short timescale (as we usually do with these prototype projects, in this case 10 days) in which to get a fully functioning system that would take raw data straight from a vehicle and present it in a graphical manner.
As I continued I kept discovering little niceties of Laszlo. For one it’s extremely simple to work with XML, binding UI elements to data just involves setting an xpath on the UI element. There are also plenty of server communication options including standard HTTP connections, RPC, and WebServices setting it up nicely for an SOA implementation. There is also a nifty persistent connection interface which allows you to push data down to the client from the server, perfect for pubsub or Instant Messaging applications.
At the end of the day, I’ve come out with a very pleasant impression of Laszlo. I managed to produce an XML data driven graphical UI application in less than 10 days that most importantly worked and that our customer was happy with.
