Data.FormValidator

Data.FormValidator's aim is to bring all the benefits of the Perl module Data::FormValidator over to JavaScript, using the same input profiles. They can be dumped into JavaScript objects using the Perl module Data::JavaScript. Profiles declare the required and optional fields and any constraints they might have. They may be shared between your backend Perl code. Frontend JavaScript validation may be done, allowing for consistent and thorough validation on both the backend and frontend. The results are provided as an object, which makes it easy to handle missing and invalid results, return error messages about which constraints failed, or process the resulting valid data.
