How can I properly use jQuery in Laravel Blade files with Vite?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I’ve encountered an issue where my inline jQuery code in a Laravel Blade file throws a '$ is not defined' error, even though I’m importing and assigning jQuery in my app.js using Vite.

I've tried several approaches and reviewed similar questions, but none have resolved my problem.

My app.js:

JAVASCRIPT
import $ from 'jquery';

$(document).ready(function () {
    ...
});

window.$ = $;

My index.blade.php file:

HTML
<html>
  <head>
    @vite(['resources/js/admin/app.js', 'resources/css/admin/app.css'])
  </head>
  <body>
    ...
    
    <script type="text/javascript">
        $(document).ready(function() {
             // Throws: $ is not defined
        });
    </script>
  </body>
</html>

I need to know how to properly use jQuery in this setup so that it’s available when my inline code executes.

The problem is that your inline script is executing before jQuery is attached to window. When you use the @vite directive, the generated module scripts (loaded with type="module" and deferred by default) may not be available immediately for inline code in the body.

How to Resolve

You have a couple of options:

Move the Inline Script into a Module File
Instead of writing your inline code in the Blade template, create a separate JavaScript file (for example, resources/js/admin/init.js) and import jquery from there. This guarantees that your code will run after the module has loaded. For example:
```
JAVASCRIPT
// resources/js/admin/init.js
import $ from 'jquery';

$(document).ready(function() {
    // Your code here.
});
```
Then update your Blade template to include both files with @vite:
```
HTML
<html>
  <head>
    @vite(['resources/js/admin/app.js', 'resources/js/admin/init.js', 'resources/css/admin/app.css'])
  </head>
  <body>
    ...
  </body>
</html>
```

Delay the Execution of the Inline Script
If you must keep the inline script in your Blade file, wrap it in an event listener that waits until the window has loaded. This ensures that the module scripts (and jQuery assignment) have been executed.

HTML
<html>
  <head>
    @vite(['resources/js/admin/app.js', 'resources/css/admin/app.css'])
  </head>
  <body>
    ...
    <script type="text/javascript">
      window.addEventListener('load', function() {
        $(document).ready(function() {
          // Your code here.
        });
      });
    </script>
  </body>
</html>

Either solution will ensure that jQuery is available when you try to use it.

Why This Happens

The @vite directive injects module scripts that are deferred, meaning they execute after the HTML parsing is complete. Plain inline scripts do not defer by default, so when the inline code runs, the deferred module might not have run yet. Moving the code into a module or waiting for the window load event helps synchronize your code execution.

You were so close... Vite loads JS as Modules, so you need to use <script type="module"> instead of <script type="text/javascript"> for this to work:

HTML
<script type="module">
  $(document).ready(function() { 
             
  });
</script>

I also have this in my vite.config.js, but I'm not 100% sure it's needed:

JAVASCRIPT
// ...
  resolve: {
    alias: {
      '$': 'jQuery',
    }
  }
