Question:
2. What template module do you use the View?
I'm a fan of Template::Declare. You can try it via Catalyst::View::Template::Declare by Jonathan Rockway. I've also used Template::Toolkit and HTML::Mason as well.
3. Do you use any _javascript_ stuff as well? I use Dojo and wondering if they can have a complimentary relationship.
I tend to prefer jQuery and friends, but Dojo should work fine. Integration of your templates with your _javascript_ library is mostly up to you, but is pretty simple to manage. There are some tools for sending back JSON or XML. I've not used it, but I'd look at Miyagawa's Catalyst::View::JSON. I have used Doran's Catalyst::Action::REST module, which takes some setup, but works well if you want a more flexible REST API and supports JSON, XML, and other formats.
Cheers,
