Symfony Main Request Trait

A convenience library for library maintainers of Symfony bundles or libraries using Symfony components. When Symfony changed the naming from master to main in multiple places this had the consequence that certain methods were deprecated in Symfony v5 and removed in v6.

This library will let you support Symfony v4-v6 and not even think about the renaming :)

Installation

composer require setono/symfony-main-request-trait

Usage

Example with the RequestStack

<?php

declare(strict_types=1);

use Setono\MainRequestTrait\MainRequestTrait;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RequestStack;

final class YourService
{
    use MainRequestTrait;

    private RequestStack $requestStack;

    public function __construct(RequestStack $requestStack)
    {
        $this->requestStack = $requestStack;
    }

    public function action(): void
    {
        /**
         * This is how you get the main request from the RequestStack. No need to worry about master/main, just get it
         * @var Request|null $request
         */
        $request = $this->getMainRequestFromRequestStack($this->requestStack);

        // do something with the request
    }
}

Example with event subscriber

<?php

declare(strict_types=1);

use Setono\MainRequestTrait\MainRequestTrait;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\KernelEvent;
use Symfony\Component\HttpKernel\KernelEvents;

final class YourSubscriber implements EventSubscriberInterface
{
    use MainRequestTrait;

    public static function getSubscribedEvents(): array
    {
        return [
            KernelEvents::RESPONSE => 'handle'
        ];
    }

    public function handle(KernelEvent $event): void
    {
        if (!$this->isMainRequest($event)) {
            return;
        }

        // Now we know we are dealing with the main request
    }
}
