Cache

config/packages/cache.php wires the PSR-6 cache subsystem and registers the cache:clear console command.

What it does

• Initialises cache.paths and cache.pools as empty merge-lists so other packages can append to them.
• Binds CacheItemPoolInterface to cache.pool.default, making the default pool available for autowiring throughout the container.
• Constructs CacheClearCommand with all registered pools and paths, then adds it to the console.

Configuration parameters

Key	Default	Description
cache.paths	[]	File paths that should be deleted when the cache is cleared. Populated by other packages (e.g. the compiled container path in services.php).
cache.pools	[cache.pool.default]	PSR-6 pool instances that CacheClearCommand will flush. Add additional pools here if your application uses more than one backend.
cache.pool.default	Defined in services.php	The default CacheItemPoolInterface implementation. The standard install uses PredisCachePool.

Console commands registered

Command	Description
cache:clear	Flushes all registered cache pools and deletes all registered cache file paths.

Customising the cache backend

Swap the default pool in services.php:

// services.php
use ForestCityLabs\Framework\Cache\Pool\FilesystemCachePool;
use League\Flysystem\Filesystem;
use League\Flysystem\Local\LocalFilesystemAdapter;
use function DI\create;

'cache.pool.default' => create(FilesystemCachePool::class)
    ->constructor(
        new Filesystem(new LocalFilesystemAdapter(__DIR__ . '/../var/cache/pool'))
    ),

Adding a second cache pool

// services.php
use function DI\add;
use function DI\get;

'cache.pools' => add([
    get('cache.pool.sessions'),
]),
'cache.pool.sessions' => create(\ForestCityLabs\Framework\Cache\Pool\PredisCachePool::class)
    ->constructor(get('redis.session_client')),
