PSR-6: Caching Interface for Drupal 8+

Installation

composer require itk-dev/drupal_psr6_cache
vendor/bin/drush pm:enable drupal_psr6_cache

or add a composer dependency on itk-dev/drupal_psr6_cache (see below for details).

Usage

Add a dependency on the drupal_psr6_cache module to a module:

# composer.json
{
    "name": "drupal/my_module",
    …
    "require": {
        "itk-dev/drupal_psr6_cache": "^1.0"
    }
}

# my_module.info.yml
…
dependencies:
  - drupal:drupal_psr6_cache

Inject the cache pool into a service:

# my_module.services.yml
my_module.some_service:
  class: Drupal/my_module/SomeService.php
  arguments:
    - '@drupal_psr6_cache.cache_item_pool'

Use the cache pool:

// src/SomeService.php
namespace Drupal/my_module;

use Psr\Cache\CacheItemPoolInterface;

class SomeService {
  __construct(CacheItemPoolInterface $cacheItemPool) {
    …
  }
}
