adjusting datepicker widget in order form

[edde_jong]

Hi there ,

I am using oye's deliovery date module as a learning method :-) (http://oyenetwork.com/articles/magento2-devliery-date-module-creation-from-scratch/)

at the order form where user gives adres and so on , there's now a nice datepicker element, it works fine.

Offcourse i want to look into that and try to make it only weekends and maybe range too, i googled a lot and found out about noweekend function and thought"well thats easy "  but WRONG !, i cant find the place where to add the noweekend option.

it should be something like 

$(function() {
 $( "#datepicker" ).datepicker({
 beforeShowDay: $.datepicker.noWeekends
 });
 });

but the closest i can find in the oyes module is

        $jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children']
        ['shippingAddress']['children']['shipping-address-fieldset']['children']['delivery_date'] = [
            'component' => 'Magento_Ui/js/form/element/abstract',
            'config' => [
                'customScope' => 'shippingAddress',
                'template' => 'ui/form/field',
                'elementTmpl' => 'ui/form/element/date',
                'options' => [],
                'id' => 'delivery-date'

in which i tried just filling in 'options' ['noweekend'] but did not bring solution 

the code of oye's order form is below 

<?php

namespace Oye\Deliverydate\Model\Checkout;

class LayoutProcessorPlugin
{

    /**
     * @param \Magento\Checkout\Block\Checkout\LayoutProcessor $subject
     * @param array $jsLayout
     * @return array
     */

    public function afterProcess(
        \Magento\Checkout\Block\Checkout\LayoutProcessor $subject,
        array  $jsLayout
    ) {
        $jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children']
        ['shippingAddress']['children']['shipping-address-fieldset']['children']['delivery_date'] = [
            'component' => 'Magento_Ui/js/form/element/abstract',
            'config' => [
                'customScope' => 'shippingAddress',
                'template' => 'ui/form/field',
                'elementTmpl' => 'ui/form/element/date',
                'options' => [],
                'id' => 'delivery-date'
            ],
            'dataScope' => 'shippingAddress.delivery_date',
            'label' => 'Delivery Date',
            'provider' => 'checkoutProvider',
            'visible' => true,
            'validation' => [],
            'sortOrder' => 200,
            'id' => 'delivery-date'
        ];
        return $jsLayout;
    }
}

 any guidance or help?
