Accelerating Perl Web Application Development

• Understand the Catalyst Framework and MVC architecture
• Build and test a site with Catalyst
• Detailed walkthroughs to create sample applications
• Extend Catalyst through plug-ins

In Detail
Many web applications are implemented in a way that makes developingthem painful and repetitive. Catalyst is an open-source Perl-basedModel-View-Controller framework that aims to solve this problem byreorganizing your web application to design and implement it in anatural, maintainable, and testable manner, making web development fun,fast, and rewarding.
Everything that your web application needs to do is only writtenonce; you connect to the database in one place, have configuration inone place, etc. Then, you just write actions for each URL that yourapplication needs, without worrying about the database connections orHTML to produce. Catalyst will handle the details so you can worryabout writing your application.
Catalyst is designed to be reliable. There are hundreds ofproduction applications and thousands of users. The code iswell-tested, and new releases almost always maintain compatibility withapplications written for older versions. You don’t have to worry aboutCatalyst breaking your application and slowing down your development.It just works.
Most importantly, Catalyst has a thriving community. You can ask aquestion on the IRC channel and get a response at almost any time ofthe day.
This book embodies Catalyst’s philosophies of Do It Yourself and Don’t Repeat Yourself.
