Elissa Bundle - PSR-7 & PSR-15 Made Easy!

Elissa Bundle by Carthage Software brings out-of-the-box PSR-7 and PSR-15 support to your Symfony project.

The package allows developers to write PSR-15 handlers and middleware, which are auto-tagged and ready to use as controllers.

It also provides ready access to all PSR-7 factories, and enables seamless integration of middleware from third-party vendor packages.

Installation 🚀

Install the Elissa Bundle using Composer with the following command:

composer require carthage-software/elissa-bundle

Enabling the Bundle 🎚

To enable the bundle in your Symfony project, add the following line in the config/bundles.php file:

return [
    //...
    CarthageSoftware\ElissaBundle\ElissaBundle::class => ['all' => true],
    //...
];

Usage 💼

PSR-7 Factories 🏭

The Elissa Bundle comes with autowired and pre-configured PSR-7 factories. You can conveniently create PSR-7 objects in your services without any extra configuration.

<?php

declare(strict_types=1);

namespace App\Service;

use Psr\Http\Message\StreamFactoryInterface;
use Psr\Http\Message\ResponseFactoryInterface;
use Psr\Http\Message\RequestFactoryInterface;
use Psr\Http\Message\ServerRequestFactoryInterface;
use Psr\Http\Message\UriFactoryInterface;
use Psr\Http\Message\UploadedFileFactoryInterface;

final class MyService
{
    public function __construct(
        private StreamFactoryInterface $streamFactory,
        private ResponseFactoryInterface $responseFactory,
        private RequestFactoryInterface $requestFactory,
        private ServerRequestFactoryInterface $serverRequestFactory,
        private UriFactoryInterface $uriFactory,
        private UploadedFileFactoryInterface $uploadedFileFactory,
    ) {}
}

PSR-15 Handlers 🎛

After installing and enabling the Elissa Bundle, writing PSR-15 handlers becomes a breeze. The handlers will automatically function as controllers in your Symfony project.

<?php

declare(strict_types=1);

namespace App\Handler;

use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ResponseFactoryInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\StreamFactoryInterface;
use Psr\Http\Server\RequestHandlerInterface;
use Symfony\Component\Routing\Annotation\Route;

final class HomeHandler implements RequestHandlerInterface
{
    public function __construct(
        private StreamFactoryInterface $streamFactory,
        private ResponseFactoryInterface $responseFactory,
    ) {}

    #[Route('/', name: 'home')]
    public function handle(ServerRequestInterface $request): ResponseInterface
    {
        $body = $this->streamFactory->createStream('Hello World!');

        return $this->responseFactory->createResponse(200)
            ->withBody($body);
    }
}

PSR-15 Middleware 🛠

Just like handlers, you can write PSR-15 middleware, and they will automatically function.

<?php

declare(strict_types=1);

namespace App\Middleware;

use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ResponseFactoryInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\StreamFactoryInterface;
use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Server\RequestHandlerInterface;

final class MadeWithMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        $response = $handler->handle($request);
        
        return $response->withHeader('X-Made-With', 'Love');
    }
}

Configurations ⚙

The Elissa Bundle is designed to minimize configuration, but if you need to register additional PSR-15 middlewares from third-party vendors, you can use the elissa.middleware service tag.

# config/services.yaml

services:
    Some\External\ServiceMiddleware:
        tags:
            - { name: elissa.middleware }
