If Laravel 5.5 is not loading jQuery or Vue.js, it could be due to a few common reasons. Let's go through some troubleshooting steps to identify and resolve the issue:

  1. Check Your Blade Layout File: Ensure that your Blade layout file (usually located in resources/views/layouts) includes the necessary JavaScript files. By default, Laravel includes jQuery and Vue.js in the resources/views/layouts/app.blade.php file. Make sure you have the following lines in your layout file:

    <!-- jQuery --> <script src="{{ asset('js/jquery.min.js') }}"></script> <!-- Vue.js --> <script src="{{ asset('js/vue.js') }}"></script>

    If your layout file is different or if you have a custom layout, make sure you have included these script tags in the appropriate location.

  2. Check File Paths: Ensure that the file paths to the jQuery and Vue.js files are correct. By default, these files are located in the public/js directory. If you have moved or renamed these files, update the file paths accordingly in your Blade layout file.

  3. Check Console for Errors: Open your browser's developer tools (usually by pressing F12 or right-clicking and selecting "Inspect") and go to the Console tab. Check if there are any JavaScript errors or 404 errors for the jQuery and Vue.js files. If there are errors, they can provide valuable clues about the issue.

  4. Check Asset Versioning: Laravel uses asset versioning to cache-bust assets for production environments. Make sure that you have run the npm run production command to compile the assets. This ensures that the latest version of the JavaScript files is being loaded.

  5. Check for Conflicts: Ensure that there are no conflicts with other JavaScript libraries or plugins that may be preventing jQuery and Vue.js from loading properly. Conflicts can occur if multiple versions of jQuery or Vue.js are included or if there are other JavaScript errors on the page.

  6. Inspect Blade Views: If you are loading jQuery and Vue.js on specific Blade views instead of the layout file, check those views for any errors or missing script tags.

  7. Cache Clearing: If you have recently made changes to your JavaScript files or the layout file, try clearing the cache to ensure that the latest changes are being served. Run the following commands:

    php artisan cache:clear php artisan view:clear
  8. Check Configuration Files: If you have modified the default configuration for Laravel's JavaScript scaffolding, make sure that the settings are correct. Check webpack.mix.js and other configuration files for any misconfigurations.

  9. Update Laravel and Packages: If you are using an older version of Laravel or its related packages, consider updating to the latest versions. Newer versions often come with bug fixes and improvements that might resolve issues.

By following these steps, you should be able to identify and fix the issue of jQuery and Vue.js not loading in your Laravel 5.5 application. If you encounter specific error messages or issues, be sure to include them in your troubleshooting, as they can provide valuable insights into the problem.
