Middleware with various cache utilities
Middleware components with the following cache utilities:
This package is installable and autoloadable via Composer as middlewares/cache.
composer require middlewares/cache
To add the response headers for cache prevention. Useful in development environments:
Dispatcher::run([ new Middlewares\CachePrevention() ]);
This middleware adds the
Cache-Control: max-age headers to the response. You can configure the cache duration for each mimetype. If it's not defined, use the defaults.
// Use the default configuration $expires = new Middlewares\Expires(); // Custom durations $expires = new Middlewares\Expires([ 'text/css' => '+1 year', 'text/js' => '+1 week', ]);
Set the default expires value if the request mimetype is not configured. By default is 1 month. Example:
Saves the response headers in a PSR-6 cache pool and returns
304 responses (Not modified) if the response is still valid. This saves server resources and bandwidth because the body is returned empty. It's recomended to combine it with
Expires to set the lifetime of the responses.
$cachePool = new Psr6CachePool(); Dispatcher::run([ new Middlewares\Cache($cachePool), new Middlewares\Expires() ]);
Optionally, you can provide a
Psr\Http\Message\ResponseFactoryInterface as the second argument to create the
304 empty responses. If it's not defined, Middleware\Utils\Factory will be used to detect it automatically.
$cachePool = new Psr6CachePool(); $responseFactory = new MyOwnResponseFactory(); $cache = new Middlewares\Cache($cachePool, $responseFactory);
