Labrador HTTP CORS

A PHP 8+ library intended to provide spec-compliant CORS middleware for projects running on Amp’s http-server.
Though this library lives under the Labrador namespace it has only one dependency, amphp/http-server, and does not depend
on any other Labrador packages.

Installation

Composer is the only supported method for installing Labrador packages.

composer require cspray/labrador-http-cors

Below is an example using the fluent API. Please check out the documentation for more details and examples of non-fluent

use Cspray\Labrador\Http\Cors\ConfigurationBuilder;
use Cspray\Labrador\Http\Cors\SimpleConfigurationLoader;
use Cspray\Labrador\Http\Cors\CorsMiddleware;
$configuration = ConfigurationBuilder::forOrigins('https://example.com', 'https://foo.example.com')
    ->allowMethods('GET', 'POST', 'PUT', 'DELETE')
    ->withMaxAge(8600)
    ->allowRequestHeaders('X-Request-Header')

    ->doAllowCredentials()
    ->build();
$loader = new SimpleConfigurationLoader($configuration);
$middleware = new CorsMiddleware($loader);
