FORM PART VALIDATOR

The validator allows you to specify easily what each input should contain to be valid you can then watch for errors :

import Validator from "./validator.js";

const validator = new Validator();
validator.watch(document.querySelectorAll("input"));

you simply add a keyword to it's data-form-constraints attribute, separated by spaces :

<input type="text" name="foo" data-form-constraints="length:0:38 nodot nowhitespace nonumber">

this will, when using the watch function, produce an error badge when the input doesn't match it's constraints
