Why use it?
-----------

[](#why-use-it)

Exposing your application's validation rules can be very useful for e.g. completely separated frontend applications. Imagine a React frontend for your API being able to realtime configure (very fast) local validation rules exactly matching your CakePHP API backend's validation rules. Some benefits:

- no more mismatches between local and backend validations
- backend validation changes instantly applied in frontend application
- no more fire-and-hope POSTing of data
- less local 412 validation errors
