I can help you with this jQuery/DataTables error in your Backpack implementation. This is a common issue that occurs when jQuery isn't properly loaded before DataTables tries to use it.

Based on the knowledge sources, there are several possible causes and solutions:

1. jQuery Loading Order: The error "Uncaught ReferenceError: $ is not defined" typically happens when scripts that depend on jQuery are loaded before jQuery itself. This has been reported in several issues with Backpack, particularly in list views with DataTables.

2. Possible Solutions:

   • Check APP_URL: Make sure your APP_URL in the .env file is set correctly. As mentioned in one issue, changing APP_URL from "localhost" to the correct domain (like "http://yourproject.test") solved this problem for some users.

   • Clear Cache: Try running php artisan cache:clear and php artisan view:clear to ensure you're not using cached versions of views or assets.

   • Check for Duplicate jQuery: Some users reported that having multiple versions of jQuery loaded caused conflicts. If you've added jQuery manually in your views, this might be causing the issue.

   • Publish Assets: Try republishing Backpack assets with php artisan vendor:publish --force and select the Backpack assets option.

3. Similar Issues: In issue #3034, a user found that their template included its own DataTables version which conflicted with Backpack's version.

4. Check Browser Console: Look for any other errors in your browser console that might provide more context about what's failing to load.

If these solutions don't work, you might need to check if you've customized any views or if there are any JavaScript errors preventing the proper loading of resources. The error suggests that jQuery isn't available when DataTables tries to initialize, which is a dependency issue rather than a problem with your CRUD setup itself.

Let me know if any of these solutions help resolve your issue!

Hello.

We are aware of the current issue with unpkg :(

So we’re already working on Basset v2. It will make it much easier to swap assets without touching views, support local caching and pushing to production.

Meanwhile, can you add BASSET_DEV_MODE=false to your .env and run php artisan basset:cache

This will force caching the assets locally and server from the local cache.

Cheers!
