Laravel provides a unified API for various caching systems. The cache configuration is located in the .env file. In this file you may specify which cache driver you would like used by default throughout your application. Laravel supports popular caching backends like Memcached and Redis out of the box.

Differences From Laravel

The Lumen cache drivers utilize the exact same code as the full Laravel cache drivers. Beyond configuration, there are no differences between using the cache in Lumen and using the cache in Laravel; therefore, please consult the full Laravel documentation for usage examples.

Note: Before using the Cache facade, be sure you have uncommented the $app->withFacades() method call in your bootstrap/app.php file.

Redis Support

Before using a Redis cache with Lumen, you will need to install the predis/predis (~1.0) and illuminate/redis (5.4.*) packages via Composer. Then, you should register the Illuminate\Redis\RedisServiceProvider in your bootstrap/app.php file.

If you have not called $app->withEloquent() in your bootstrap/app.php file, then you should call $app->configure('database'); in the bootstrap/app.php file to ensure the Redis database configuration is properly loaded.
