Why?
Since switching the bulk of my programming work from Angular to Vue I was missing a simple to use and lightweight form validation library. I was looking for something similar to Angulars's Reactive forms and FormBuilder APIs. After a bit of tinkering, I found that something like this is easily achievable by building on top of Vue's powerful reactivity system. I've been using a private version of this library for most of my projects for a while now. I've decided to clean things up, write some documentation and make it a proper publicly available library.
Other stuff
If this library is not your jam check out one of the other great form validation libraries out there:
