Put a `Cache` in queue and use a `PSR-6 Cache` (`Filesystem` as backend - but you could also use `Redis`, `Memcached`, `MySQL` or any other backend implemented a `PSR-6` caching layer ...): ``` /** * Fill queue for running "Caching Middleware" * * @param \Psr\Http\Message\ServerRequestInterface $request Request (PSR) to process * @param \Psr\Http\Message\ResponseInterface $response Response (PSR) to use * @param callable $next Next middleware in stack * * @return \Psr\Http\Message\ResponseInterface A PSR compatible response */ $queue[] = function (Request $request, Response $response, callable $next) { // Create cache item factory $cacheItemFactory = function ($key) { return new CacheItem($key); }; // Create cache item key factory $cacheItemKeyFactory = function (Request $request) { static $key = null; if (null === $key) { $uri = $request->getUri(); $slugify = new Slugify(); $key = $slugify->slugify(trim($uri->getPath(), '/').($uri->getQuery() ? '?'.$uri->getQuery() : '')); } return $key; }; // Get cache $cachingMiddleWare = new Clickalicious\Caching\Middleware\Cache( new CacheItemPool('Filesystem'), $cacheItemFactory, $cacheItemKeyFactory ); return $cachingMiddleWare($request, $response, $next); }; ``` Requirements ------------ [](#requirements) - `PHP >= 5.6` (compatible up to version `7.2` as well as `HHVM`) Philosophy ---------- [](#philosophy) `Caching Middleware` is a `PSR-7` compatible middleware based on `PSR-6` compatible cache implementations. `Caching Middleware` isn't a unicorn - it's good but it maybe going to change with time. Try it, run it ... ♥ it ;) Versioning ---------- [](#versioning) For a consistent versioning we decided to make use of `Semantic Versioning 2.0.0` . Its easy to understand, very common and known from many other software projects. Roadmap ------- [](#roadmap) - Cache whole response instead just rendered HTML (Headers as well for example) - Implement [flysystem](http://flysystem.thephpleague.com/ "flysystem") as Driver for `PSR-Cache` [![Throughput Graph](https://camo.githubusercontent.com/57356211685a077ef69d62f708eacc1c4ef7e49cfe43ea8f331271e66f719d8c/68747470733a2f2f6772617068732e776166666c652e696f2f636c69636b616c6963696f75732f63616368696e672d6d6964646c65776172652f7468726f7567687075742e737667)](https://waffle.io/clickalicious/caching-middleware/metrics) Security Issues --------------- [](#security-issues) If you encounter a (potential) security issue don't hesitate to get in contact with us `opensource@clickalicious.de` before releasing it to the public. So i get a chance to prepare and release an update before the issue is getting shared. Thank you! Participate & Share ----------------------- [](#participate--share) ... yeah.
