This screencast shows how easy it is to create a web application form with HTML5 form fields and client and server-side validation using Mojolicious::Lite, Validation::Class and Validation::Class::Plugin::FormFields. #cpan #perl #mojolicious

I has only just occurred to me that Validation::Class is not a new approach, concept or execution for me. It is merely the result of a refinement process after lots of trial-and-error (mostly error) and time.

Where are we now:

Validation::Class now has a pretty solid core and test coverage, a plugin system, and I just git-push'd an HTML form field rendering p…

I have completely rewritten Validation-Class using Moose. The new Validation::Class is better documented and well-tested.
