Laravel 4 redis cache fallback to file

Redis cache fallback for Laravel4

If you use Redis as cache driver on Laravel 4 and for some reason Redis server became unavailable, you will end up with a Connection Refused exception. This package simply checks for the connection and if test fails, cache is switched to file driver. As soon as Redis come back it will be used again., _(*1)

How it works

LaravelRedisFallbackServiceProvider class extends Illuminate\Cache\CacheServiceProvider and overrides register() method as follow:, _(*2)

    public function register(){

        $this->app->bindShared('cache', function($app){
            return new \Davidepedone\LaravelRedisFallback\LaravelRedisFallback($app);
        });
        ...
    }

LaravelRedisFallback class extends Illuminate\Cache\CacheManager and overrides createRedisDriver() method as follow:, _(*3)

    protected function createRedisDriver() {

        $redis = $this->app['redis'];
        $redisStore = new RedisStore($redis, $this->getPrefix());

        try{

            $redisStore->getRedis()->ping();
            return $this->repository( $redisStore );

        }catch(\Exception $e){

            return parent::createFileDriver();
        }

    }

How to use

Install LaravelRedisFallback as a Composer package, adding this line to your composer.json:, _(*4)

"davidepedone/laravel-redis-fallback": "dev-master"

and update your vendor folder running the composer update command., _(*5)

Replace the default cache service provider:, _(*6)

'providers' => array(
    ...
    //'Illuminate\Cache\CacheServiceProvider',
    ...
    'Davidepedone\LaravelRedisFallback\LaravelRedisFallbackServiceProvider'
    ...
)

Enjoy!, _(*7)
