Using Partytown with Shopify App Extension Scripts

[bennobuilder]

Hey everyone,

I'm exploring the possibility of using Partytown to load scripts for Shopify app extensions. As far as I know, this isn't feasible due to Partytown's requirement for library files to be hosted on the same origin as the webpage (see lib config). Shopify app extensions are served from Shopify's CDN (https://cdn.shopify.com/), which differs from the store's origin (https://bennos-dev-store.myshopify.com/).

I attempted to configure the Partytown library path in a Shopify app extension, but the differing origins seem to violate Partytown's requirements:

    {% assign full_url = 'partytown.js' | asset_url %}
    {% assign url_parts = full_url | split: '/' %}
    {% assign partytown_lib_path = '/'
        | append: url_parts[3]
        | append: '/'
        | append: url_parts[4]
        | append: '/'
        | append: url_parts[5]
        | append: '/'
        | append: url_parts[6]
        | append: '/'
    %}
    <script>
        partytown = {
            lib: '{{ partytown_lib_path }}'
        };
    </script>
    <script type='module' src='{{ 'partytown.js' | asset_url }}'></script>
    <script type="text/partytown" src="https://example.com/random-script.js"></script>

With this setup, Partytown tries to load the scripts from the origin:

https://bennos-dev-store.myshopify.com/extensions/03b259ba-6447-4248-a82e-7be394c9b5db/0.0.0/assets/partytown-sw.js

although they are only available at the Shopify CDN:

https://cdn.shopify.com/extensions/03b259ba-6447-4248-a82e-7be394c9b5db/0.0.0/assets/partytown-sw.js

Since the Partytown main script is also served from the Shopify CDN, is it somehow possible to make Partytown work in this environment?

Thanks :)
