Form schema validation library.

let's get fonky

Fonk is a pure javascript, framework agnostic, form validation library.

It allows you to:

  • Define validations that apply to your form in a declarative way.
  • Isolate your form validation business logic from the ui.
  • Unit test your form validation without having to mount the ui.
  • Create reusable validation rules that can be easily unit tested.


Live Demo (Fonk + React Final Form)

Fonk can be easily plugged into many libraries / frameworks or just be used in plain vanilla js.

Available integration examples:

Coming soon integration examples:

  • Vuejs.
