Using Yii's validators with frontend frameworks

Has anyone experimented with using Yii’s validators (serverside) with Angular?

You don’t realize how Yii helps you until you have to write validators in Angular, so I got to thinking…

Why not use Yii’s model validators, call them the same way as a frontend written in Yii would do, and capture the output (success/failure) on the Angular side and show on the form?
