• Slim Framework 3.0

How to use

Register CacheMiddleware to Slim Dependency Container

<?php
...
use Juhara\ZzzCache\Contracts\CacheInterface;
use Juhara\ZzzCache\Cache;
use Juhara\ZzzCache\Storages\File;
use Juhara\ZzzCache\Helpers\ExpiryCalculator;
use Juhara\ZzzCache\Helpers\Md5Hash;

$container[CacheInterface::class] = function ($c) {
    // create a file-based cache where all cache
    // files is stored in directory name
    // app/storages/cache with
    // filename prefixed with string 'cache'
    return new Cache(
        new File(
            new Md5Hash(),
            'app/storages/cache/',
            'cache'
        ),
        new ExpiryCalculator()
    );
};

use Juhara\CacheMiddleware\CacheMidleware;
use Juhara\CacheMiddleware\ResponseCacheFactory;

$container[CacheMiddleware::class] = function ($c) {
    $cache = $c->get(CacheInterface::class);
    $factory = new ResponseCacheFactory();
    return new CacheMiddleware($cache, $factory);
};

Add CacheMiddleware to Slim Application

use Slim\App;
use  Juhara\CacheMiddleware\CacheMiddleware;

$app = new App($settings);
...
$app->add(CacheMiddleware::class);

Create Proper Configuration

If using Juhara\ZzzCache\Storages\File as storage, then you need to make sure that directory of cache is writeable by web server.
