Describe the process of implementing custom caching strategies in Slim Framework.

Describe the process of implementing custom caching strategies in Slim Framework.

Here’s a minimal approach to implementing custom caching strategies in Slim Framework:

1. Install a Caching Library

Install Symfony Cache via Composer:

Example

composer require symfony/cache

2. Set Up the Cache

Create a cache instance, such as a file-based cache:

Example

<?php
use Symfony\Component\Cache\Adapter\FilesystemAdapter;

$cache = new FilesystemAdapter(); // or RedisAdapter, etc.
?>

3. Implement Caching in Routes

Use the cache to store and retrieve data in a Slim route:

Example

<?php
$app->get('/data', function ($request, $response, $args) use ($cache) {
    $cacheKey = 'data_key';

    // Check cache
    $cachedData = $cache->getItem($cacheKey);
    if (!$cachedData->isHit()) {
        // Cache miss, fetch fresh data
        $data = fetchDataFromDatabase(); // or external API

        // Store in cache for 1 hour
        $cachedData->set($data)->expiresAfter(3600);
        $cache->save($cachedData);
    }

    // Return cached or fresh data
    return $response->withJson($cachedData->get());
});
?>

4. Clear Cache (Optional)

If needed, clear cache:

Example

<?php
$cache->deleteItem('data_key');
?>
