catalog/product/composite/configure.js does not support RequireJS mixins because it doesn't return a module

[miljkovic5]

Preconditions and environment

Preconditions

• Magento 2.4.x (tested on 2.4.7)
• Admin panel, product composite configuration popup
• JS module: Magento_Catalog/catalog/product/composite/configure.js

Steps to reproduce

1. Try to create a mixin for ProductConfigure via config.mixins in requirejs-config.js
2. Magento ignores the mixin
3. I'm forced to patch window.ProductConfigure using a setTimeout or poller pattern

Expected result

The file should return the ProductConfigure constructor as an AMD module to extend it via proper config.mixins mechanism.

Actual result

The file does not return anything, so require('Magento_Catalog/catalog/product/composite/configure') returns undefined, and RequireJS mixins cannot be applied.

Additional information

This is backward-compatible and would allow proper mixin usage without breaking global usage (window.ProductConfigure = ProductConfigure).

Hello @miljkovic5,

Thanks for the report and collaboration!

We have tried to reproduce the issue in the latest 2.4-develop branch and it seems to reproducible for us. In order to reproduce it, we have created a custom module with the below code:

product-configure-mixin.js

define([], function () {
    'use strict';
    return function (ProductConfigure) {
        // Try to extend or modify ProductConfigure
        ProductConfigure.prototype.myCustomMethod = function () {
            console.log('Mixin applied!');
        };
        return ProductConfigure;
    };
});

requirejs-config.js

var config = {
    config: {
        mixins: {
            'Magento_Catalog/catalog/product/composite/configure': {
                'Magz_Issues39908/js/product-configure-mixin': true
            }
        }
    }
};

As per the expected result, it should log in the console Mixin applied!, but it shouldn’t by clicking on the configure button in admin panel for configurable product.

Is this the correct way to reproduce this issue? Or we have missed anything.

Thanks
