I have a piece of javascript that acts upon the reloadPrice function. It inserts a block of html into the dom to add a corresponding sample product (cloth sample for sofas). This works fine so far.

But to make sure a sample does not get added to cart more than once I need to access the quote (check items) via javascript. Now I am struggeling how to do it.

This is my code:

], function ($, $t, quote, wrapper) {
    'use strict';

    return function(targetModule){

        var reloadPrice = targetModule.prototype._reloadPrice;
        var reloadPriceWrapper = wrapper.wrap(reloadPrice, function(original) {
            var result = original();

            var simple = this.options.spConfig.children[this.simpleProduct];

            if (typeof simple != 'undefined') {
                if (simple.sample != '') {


                    if ($('#order-sample').length) {
                    } else {
                        addToCartButtonTextDefault: $.mage.__('Order a cloth sample')
                } else {

            return result;

        targetModule.prototype._reloadPrice = reloadPriceWrapper;
        return targetModule;

My idea was to inject Magento_Checkout/js/model/quote and check the quote's items using getItems. Unfortunately this does only work inside the cart/checkout. When I use it like above I get the error TypeError: window.checkoutConfig is undefined in the console.

So my question is: how can I access the cart/quote and it's items outside checkout via javascript.

Thank you
