Add preload URLs generator and refactored caching strategy

[Spomky]

Introduced a preload URLs generator to efficiently handle URLs and refactored caching strategy to enhance efficiency. The changes include creating a preload URLs generator manager, implementing a dummy URLs generator for testing, and updating cache resource classes. Deprecated PageCache in favor of ResourceCache for better flexibility in handling resources.

Target branch: 1.2.x Resolves issue #154

How to use it?

1. Create your generator

   
   <?php

declare(strict_types=1);

namespace Acme\Services;

use SpomkyLabs\PwaBundle\CachingStrategy\PreloadUrlsGeneratorInterface; use SpomkyLabs\PwaBundle\Dto\Url;

class MyCustomUrlsGenerator implements PreloadUrlsGeneratorInterface { /**

• @return iterable<Url|string> */ public function generateUrls(): iterable { yield '/dummy/1'; yield Url::create('app_page', ['id' => 1]); yield Url::create('app_page', ['id' => 2]); } }

Declare this class as a service with a tag and unique alias

// config/services.php
namespace Symfony\Component\DependencyInjection\Loader\Configurator;

return function(ContainerConfigurator $container): void {
    $services = $container->services();

    $services->set(\Acme\Services\MyCustomUrlsGenerator ::class)
        ->tag('spomky_labs_pwa.preload_urls_generator', ['alias' => 'my-generator'])
    ;
};

Use it in your configuration. The alias shall be prefixed with @

pwa:
    serviceworker:
        workbox:
            resource_caches:
                - match_callback: 'navigate'
                  preload_urls:
                      - '@my-generator'

Is it possible to skip the manual wiring of the class in services.php|yaml and simply reference the class in the pwa.yaml config?

pwa:
    serviceworker:
        workbox:
            resource_caches:
                - match_callback: 'navigate'
                  preload_urls:
                      - 'Acme\Services\MyCustomUrlsGenerator'

I changed the interface. It is now required to indicate the alias so that the service declaration is much simple. Also, I created an attribute to indicate the whole controller class or the method should be preloaded.

<?php

namespace App\Controller;

use App\Form\ItemHandler;
use App\Repository\ItemRepository;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Attribute\Route;
use SpomkyLabs\PwaBundle\Attribute\PreloadUrl;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

#[PreloadUrl(alias: 'fooBar', params: ['_locale' => 'fr'], pathTypeReference: UrlGeneratorInterface::ABSOLUTE_URL)]
class HomepageController extends AbstractController
{
    public function __construct(
        private readonly ItemHandler $itemHandler,
        private readonly ItemRepository $itemRepository,
    ){}

    #[PreloadUrl(alias: 'homepage', params: ['_locale' => 'fr'])]
    #[PreloadUrl(alias: 'homepage', params: ['_locale' => 'en'])]
    #[PreloadUrl(alias: 'homepage', params: ['_locale' => 'it'])]
    #[Route('/', name: 'app_homepage', methods: [Request::METHOD_GET])]
    public function homepage(): Response
    {
        return $this->render('homepage/index.html.twig');
    }

    #[Route('/terms-of-service', name: 'app_tos', methods: [Request::METHOD_GET])]
    public function tos(): Response
    {
        return $this->render('tos/index.html.twig');
    }
}

Aliases are managed automatically. You just need to add @homepage or @fooBar to have them listed in the resource cache.

• @homepage will contain /?_locale=en, /?_locale=fr and /?_locale=it
• @fooBar will contain https://example.com/?_locale=fr and https://example.com/terms-of-service?_locale=fr
