Middleware that caches the response code and body of an URL list

Install

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.

composer require wyrihaximus/react-http-middleware-response-cache

This middleware caches the response code and body from a list of given URL's. Note that not headers will be cached at this point. The middleware accepts a cache configuration implementing CacheConfigurationInterface as first argument which will decide when to store something in the cache and what. As second argument it accepts a cache implementing CacheInterface so either ArrayCache shipping with react/cache or any cache implementing CacheInterface from the cache implementations listed at the ReactPHP users wiki.

Usage

$server = new Server([
    /** Other middleware */
    new ResponseCacheMiddleware(
        new CacheConfiguration(
            [
                '/',
                '/robots.txt',
                '/favicon.ico',
                '/cache/***', // Anything that starts with /cache/ in the path will be cached
                '/api/???', // Anything that starts with /cache/ in the path will be cached (query is included in the cache key)
            ],
            [ // Optional, array with headers to include in the cache
                'Content-Type',
            ]
        ),
        new ArrayCache() // Optional, will default to ArrayCache but any CacheInterface cache will work. 
    ),
    /** Other middleware */
]);
