How to validate a date format in version 3

[gkuper]

I found example of using a rule "date_format". It looks like this was removed between version 2.x and 3. Is there another way to do this with vee-validate now?

Thanks for your time.

You can implement your own rules, you will probably need to use a 3rd party library like date-fns as well.

import { parse } from 'date-fns';
import { defineRule, isValid } from 'vee-validate'; // or `extend` if vee-validate is v3

defineRule('date_format', (value, [format]) => {
   const d = parse(format, value);

  return isValid(d) ? true : 'Invalid date';
});
