Assets added by @vite being blocked by cors

The issue you're experiencing with CORS (Cross-Origin Resource Sharing) is likely due to the fact that your assets are being served from a different subdomain than your main application. Browsers enforce CORS policies to prevent security issues, and this can cause problems when assets are loaded from different origins.

To resolve this, you need to configure your server to allow cross-origin requests for your assets. Here’s a step-by-step solution:

1. Configure CORS in your server: Ensure that your server is set up to allow requests from your subdomains. If you're using Laravel, you can use the fruitcake/laravel-cors package to handle CORS.

2. Install the CORS package:

   composer require fruitcake/laravel-cors
   

3. Publish the configuration:

   php artisan vendor:publish --tag="cors"
   

4. Configure the CORS settings: Open the config/cors.php file and configure it to allow your subdomains. You can use a wildcard for subdomains like this:

   return [
       'paths' => ['api/*', 'sanctum/csrf-cookie', 'your-vite-assets-path/*'],
       'allowed_methods' => ['*'],
       'allowed_origins' => ['*.yourdomain.com'],
       'allowed_origins_patterns' => [],
       'allowed_headers' => ['*'],
       'exposed_headers' => [],
       'max_age' => 0,
       'supports_credentials' => false,
   ];
   

5. Ensure Vite is serving assets with the correct headers: If you're using Vite's development server, you might need to configure it to allow CORS. You can do this by adding a server configuration in your vite.config.js file:

   export default {
       server: {
           cors: {
               origin: 'http://*.yourdomain.com',
               methods: ['GET', 'POST', 'PUT', 'DELETE', 'OPTIONS'],
               allowedHeaders: ['Content-Type', 'Authorization'],
               credentials: true
           }
       }
   }
   

6. Check your web server configuration: If you're using Nginx or Apache, make sure they are configured to allow CORS. For Nginx, you can add the following to your server block:

   add_header 'Access-Control-Allow-Origin' '*';
   add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
   add_header 'Access-Control-Allow-Headers' 'Content-Type, Authorization';
   

   For Apache, you can add the following to your .htaccess file or your virtual host configuration:

   <IfModule mod_headers.c>
       Header set Access-Control-Allow-Origin "*"
       Header set Access-Control-Allow-Methods "GET, POST, OPTIONS"
       Header set Access-Control-Allow-Headers "Content-Type, Authorization"
   </IfModule>
   

By following these steps, you should be able to resolve the CORS issues and allow your Vite-built assets to be loaded correctly from your subdomains.
