how to add cors origin in public folder laravel


If you're working on a Laravel application, you might encounter Cross-Origin Resource Sharing (CORS) issues when your frontend application is hosted on a different domain than your Laravel API. CORS is a security feature implemented in web browsers to prevent malicious websites from accessing resources from another domain without permission. In this article, we will guide you on how to add CORS origins in your Laravel project, specifically focusing on configuring the CORS settings directly in the public folder.

Understanding the Problem

Here's the original problem scenario:

To rephrase it for clarity, we can say: "How can I configure CORS origins in the public folder of a Laravel application?"

Step-by-Step Guide to Add CORS in Laravel

Step 1: Install CORS Package

Laravel provides a simple way to manage CORS with the help of a package called barryvdh/laravel-cors. You can easily install this package via Composer. Run the following command in your terminal:

composer require barryvdh/laravel-cors

Step 2: Publish the Configuration File

After installing the package, you need to publish the configuration file to customize it as per your requirements. Use this command:

php artisan vendor:publish --provider="Barryvdh\Cors\ServiceProvider"

This will create a cors.php configuration file in the config directory of your Laravel project.

Step 3: Configure CORS Settings

Open the newly created config/cors.php file. Here you can specify the allowed origins, methods, headers, and more. To allow all origins (which may not always be recommended in production), you can set:

'paths' => ['api/*'],
'allowed_methods' => ['*'],
'allowed_origins' => ['*'], // or specify your domains
'allowed_origins_patterns' => [],
'allowed_headers' => ['*'],
'exposed_headers' => [],
'max_age' => 0,
'supports_credentials' => false,

For better security, consider specifying the exact domains instead of using *. For example:

'allowed_origins' => ['https://your-frontend-domain.com'],

Step 4: Add Middleware

After configuring CORS, you need to register it as middleware. Open app/Http/Kernel.php and add the CORS middleware to the $middleware array:

protected $middleware = [
    // other middlewares
    \Barryvdh\Cors\HandleCors::class,
];

Step 5: Test Your Configuration

To verify that CORS is working correctly, you can use tools like Postman or simply run your frontend application to check if it can successfully communicate with your Laravel API. If set up correctly, you should not see any CORS-related errors in the console.

Practical Example

Imagine you have a Laravel backend and a React frontend, hosted separately. Your React app tries to make a request to your Laravel API. If CORS isn’t configured, the browser will block the request. By following the above steps, you're allowing your React frontend to access the resources from your Laravel backend without facing CORS issues.

Conclusion

Configuring CORS in your Laravel application is essential for allowing communication between different origins securely. By following the steps outlined in this guide, you can easily add CORS origins in your public folder, ensuring your web applications can interact without running into restrictions.
