README

PSR-15 middleware for Cross-Origin Resource Sharing. It validates request origins, handles preflight OPTIONS requests, and adds CORS response headers.

Installation

composer require componenta/http-cors-middleware

This package has no config provider. Create CorsConfiguration and CorsMiddleware explicitly in the application container or route middleware list.

Quick Start

use Componenta\Http\Middleware\Cors\CorsConfiguration;
use Componenta\Http\Middleware\Cors\CorsMiddleware;

$middleware = new CorsMiddleware(
    config: new CorsConfiguration(
        allowedOrigins: ['https://example.com'],
        allowedMethods: ['GET', 'POST', 'OPTIONS'],
        allowedHeaders: ['Content-Type', 'Authorization'],
        allowCredentials: true,
    ),
    responseFactory: $responseFactory,
);

Configuration

CorsConfiguration accepts allowed origins, methods, request headers, exposed headers, optional maxAge, allowCredentials, and allowPrivateNetwork.

CorsMiddleware also requires a PSR-17 ResponseFactoryInterface to create preflight and rejection responses.

Wildcard origins and headers are supported. When credentials are enabled, wildcard handling follows browser CORS rules and specific values should be configured.

Boundary

This package only handles CORS. Authentication, CSRF, trusted proxy handling, and rate limiting are separate middleware packages.
