hasLengthLessThan

hasLengthLessThan tests that the value is less than a predefined length. It wraps a call to createValidator, so you must first call it with the max length.

import { hasLengthLessThan } from 'revalidate';

hasLengthLessThan(4)('My Field')('hello');
// 'My Field cannot be longer than 3 characters'
