CORS Middleware for Laravel

On November 18, 2020 . By CodimTh

The laravel-cors package allows you to send Cross-Origin Resource Sharing headers with Laravel middleware configuration.

Features

Handles CORS pre-flight OPTIONS requests
Adds CORS headers to your responses
Match routes to only add CORS to certain Requests

Installation

Require the fruitcake/laravel-cors package in your composer.json and update your dependencies:

composer require fruitcake/laravel-cors

If you get a conflict, this could be because an older version of barryvdh/laravel-cors or fruitcake/laravel-cors is installed. Remove the conflicting package first, then try install again:

composer remove barryvdh/laravel-cors fruitcake/laravel-cors
composer require fruitcake/laravel-cors

Global usage

To allow CORS for all your routes, add the HandleCors middleware at the top of the $middleware property of app/Http/Kernel.php class:

protected $middleware = [
  \Fruitcake\Cors\HandleCors::class,
    // ...
];

Now update the config to define the paths you want to run the CORS service on, (see Configuration below):

'paths' => ['api/*'],

Configuration

The defaults are set in config/cors.php. Publish the config to copy the file to your own config:

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

Note: When using custom headers, like X-Auth-Token or X-Requested-With, you must set the allowed_headers to include those headers. You can also set it to ['*'] to allow all custom headers.
