rekalogika/psr-16-simple-cache-bundle

Enables PSR-16 Simple Cache services in Symfony projects. These were previously enabled in the older Symfony version but were removed in 4.3.

Installation

Make sure Composer is installed globally, as explained in the installation chapter of the Composer documentation.

With Symfony Flex

Open a command console, enter your project directory, and execute:

composer require rekalogika/psr-16-simple-cache-bundle

Without Symfony Flex

Step 1: Download the Bundle

Open a command console, enter your project directory, and execute the following command to download the latest stable version of this bundle:

composer require rekalogika/psr-16-simple-cache-bundle

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

config/bundles.php

return [
    // ...
    Rekalogika\Psr16SimpleCacheBundle\RekalogikaPsr16SimpleCacheBundle::class => ['all' => true],
];

Usage

Callers can simply wire in Psr\SimpleCache\CacheInterface. The service uses the same underlying pool used by Symfony's CacheInterface.

use Psr\SimpleCache\CacheInterface;

class SomeService
{
    public function __construct(private CacheInterface $cache)
    {
    }

    public function doSomething()
    {
        $this->cache->set('foo', 'bar');
    }
}

Rationale

We are using PSR-16 mostly as an expiring key-value storage. While PSR-6 and Symfony's CacheInterface are more powerful and easier to use for caching things, we don't feel their interfaces are suitable for key-value storage.

Credits

This package is just a service definition. The actual implementation is done by the Symfony project; they just don't make the service available by default.
