SofascorePurgatoryBundle

Purgatory is a Symfony bundle for HTTP cache invalidation, designed to automatically generate and send cache purge requests to HTTP cache backends like Symfony's HTTP cache or Varnish. It leverages Doctrine events to track changes in entities and generates URLs that need purging based on configured routes.

Features

• Doctrine Event Integration: Listens to Doctrine lifecycle events (postUpdate, postRemove, postPersist) to automatically detect when entities are modified, created, or deleted.

• Automatic URL Generation: Automatically generates purge requests for relevant URLs based on the affected entities and their associated routes.

• Flexible Configuration:

  • Primary configuration is done through the #[PurgeOn] attribute, allowing you to annotate controller actions with cache purge rules based on entities used in the response.
  • Supports YAML configuration for flexibility depending on your project's requirements.

• Built-in Purger Support: Comes with built-in support for Symfony HTTP Cache and a basic Varnish implementation. For advanced use cases, you can create custom purgers by implementing the PurgerInterface.

• Asynchronous Processing: Includes built-in support for Symfony Messenger to process purge requests asynchronously for better scalability and efficiency.

Requirements

• PHP 8.1 or higher
• Symfony 5.4 or Symfony 6.4 or higher

Installation

Require the bundle using Composer:

composer require sofascore/purgatory-bundle

If your project doesn't use Symfony Flex, continue with the following steps:

1. Create a configuration file under config/packages/purgatory.yaml. Here's a reference configuration:

   purgatory:
   
       # List of files or directories where Purgatory will look for additional purge definitions.
       mapping_paths:        []
   
       # Route names that match the given regular expressions will be ignored.
       route_ignore_patterns: []
   
           # Examples:
           # - /^_profiler/
           # - /^_wdt/
       doctrine_middleware:
           enabled:              true
   
           # Explicitly set the priority of Purgatory's Doctrine middleware.
           priority:             null
   
       # Explicitly set the priorities of Purgatory's Doctrine event listener.
       doctrine_event_listener_priorities:
           preRemove:            null
           postPersist:          null
           postUpdate:           null
   
           # This event is not registered when the Doctrine middleware is enabled.
           postFlush:            null
       purger:
   
           # The ID of a service that implements the "Sofascore\PurgatoryBundle\Purger\PurgerInterface" interface
           name:                 null # Example: symfony
   
           # The hosts from which URLs should be purged
           hosts:                []
   
           # The service ID of the HTTP client to use, must be an instance of Symfony's HTTP client
           http_client:          null
       messenger:
   
           # Set the name of the messenger transport to use
           transport:            null
   
           # Set the name of the messenger bus to use
           bus:                  null
   
           # Set the number of urls to dispatch per message
           batch_size:           null
   
       # Enables the data collector and profiler panel if the profiler is enabled.
       profiler_integration: true

2. Enable the bundle in config/bundles.php by adding it to the array:

   Sofascore\PurgatoryBundle\PurgatoryBundle::class => ['all' => true],
