[PP-1] Make Media Library widget work when JS aggregation is enabled

Thanks, @akhil babu! 😄

Couldn't figure out why the widget is not working with js aggregation enabled :( Maybe something to do with the order in which the js is executed?

So I think I understand why this is happening, but I'm not yet sure how to solve it yet:

In experience_builder/ui/src/services/processResponseAssets.ts we have:

    try {
      await Drupal.AjaxCommands.prototype['add_js'](
        {
          instanceIndex: Drupal.ajax.instances.length + 1,
          selector: 'head',
        },
        {
          command: 'add_js',
          status: 'success',
          data: js.filter(
            (item: JsAttachItem) =>
              item.src && !document.querySelector(`script[src="${item.src}"]`),
          ),
        },
      );
    } catch (e) {
      console.error(e);
    }
  }

The following line:

item.src && !document.querySelector(`script[src="${item.src}"]`),

makes sure we don't add a JavaScript file that's already been added. The problem is that when we have aggregation enabled the file name is random and will contain multiple libraries/files.

So what's happening here is that multiple JS files already loaded will be loaded again, and e.g core/misc/ajax.js gets loaded twice, and I can see that it doesn't get the commands registered correctly (openDialog, closeDialog) from e.g dialog.ajax.

If aggregation is on in console I see

processResponseAssets.ts:45 TypeError: Cannot read properties of undefined (reading 'prototype')
    at processResponseAssets (processResponseAssets.ts:36:33)
    at executeEndpoint (chunk-ROQIBUHR.js?v=6a6fe84e:757:37)
    at async chunk-4IJSOCZX.js?v=6a6fe84e:2594:27
    at async Promise.all (index 1)

upon logging Drupal we get- the ajax,AjaxCommands is not getting attached.

Turns out ajax, AjaxCommands are not getting attached because of this error

Uncaught 
TypeError: Cannot read properties of null (reading 'classList')

this error comes from core/themes/olivero/js/navigation-utils.js. I solved this error manually and media library widget works with aggregation on.

Moving this to needs review just to check If others getting same error in console.

I am also encountering the same issue when JavaScript aggregation is enabled.

I tested MR 277 and the media library widget works fine with JS aggregation enabled

@akhil babu,

Check the screenshot in IS, the media library widget should look like it.

Please test again with a fresh install.
1. Install Drupal
2. Enable Media, Media Library, XB, Xb Vite Integration modules,
3. Add article and go xb/node/1
4. Click on the image component & check the console for errors.
5. If you click on Add Media it does not work.

Unassigning myself. I will check this once this issue 🐛 XBEndpointRenderer & processResponseAssets() do not support `ajaxPageState` ⇒ duplicate CSS/JS loading Needs review is fixed.

I was going to say this too, I'm ~90% confident that 🐛 XBEndpointRenderer & processResponseAssets() do not support `ajaxPageState` ⇒ duplicate CSS/JS loading Needs review will fix this. See my detailed analysis at #3472900-13: XBEndpointRenderer & processResponseAssets() do not support `ajaxPageState` ⇒ duplicate CSS/JS loading → for why.

(I haven't read this issue in detail, otherwise it'd probably be 99%.)
