Cache Middleware for Laravel/Lumen

We use two middleware for cache, one for serving response from cache and another for generating cache.

• ServeCachedResponse
  • The only job will be serve the response from cache if available
  • This middleware should be below the Authentication in the Middleware stack
• CacheReponse
  • This middleware should analyze the response for it’s cacheability by checking the cache headers
  • If the response is cacheable, it should cache the response in configured cache store(Redis)
  • Currently, We are using only cache-control directive to cache the response

The package uses Laravel Cache to store and serve response. Any response having cache-control directive with max-age will be cached for duration defined in max-age parameter.

Installing the package using composer

composer require geniussystems-np/cache-middleware

Once the package is installed, enable the Middleware in app/Http/Kernel.php and add to your required middleware group.

protected $middleware = [
        \App\Http\Middleware\TrustHosts::class,
        \App\Http\Middleware\TrustProxies::class,
        \Fruitcake\Cors\HandleCors::class,
        \App\Http\Middleware\PreventRequestsDuringMaintenance::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
        .
        .
        \GeniusSystems\Http\Middleware\ServeCachedResponse::class,
        .
        .
        \GeniusSystems\Http\Middleware\CacheResponse::class,
  ];

ServeCacheResponse should be after authentication middleware since it doesn’t pass the request to other middleware in the stack if there’s a response. Above code asumes you’re enabling cache-middleware for all the routes. For specific routes, you need to added the middleware to it’s respective group and enable middleware in route.
