Catalyst is an elegant, open source web application framework,
flexible yet very simple. This means that developers can help build
applications that run on the web, or that run using protocols used for
the web. Catalyst is designed to make it easy to manage the various
tasks you need to do to run an application on the web, either by doing
them itself, or by letting you "plug in" existing Perl modules that do
what you need.
Catalyst is written using Moose, a modern object system for
Its design is heavily inspired by such frameworks as Ruby on Rails,
Maypole, and Spring.
Catalyst follows the Model-View-Controller (MVC) design
pattern, allowing you to easily separate concerns, like content,
presentation, and flow control, into separate modules. This separation
allows you to modify code that handles one concern without affecting
code that handles the others. Catalyst promotes the re-use of existing
Perl modules that already handle common web application concerns well.
Catalyst is based on a "don't repeat yourself" (DRY)
principle, which means that definitions should only have to be made
Catalyst is used by a number of different popular sites
iPlayer, Edit Grid, and Manchester Evening News.
