This extension currently runs on TYPO3 v10, TYPO3 v11 and TYPO3 v12, and needs PHP 7.4 or higher. Installation ------------ [](#installation) Just use `composer req b13/http2` and install the extension via the Extension Manager, flush caches and you're ready to go. In order to see if the extension works, ensure that your webserver supports HTTP/2, runs via HTTPS and check your Response headers to see if "link: " headers are added to your HTTP response. Nothing to configure, it just works(tm). Requirements ------------ [](#requirements) You need a webserver with HTTP/2 support, and - of course - HTTPS. Also, use PHP7 - if you care about performance or supported PHP versions, there is nothing to discuss. How it works under the hood --------------------------- [](#how-it-works-under-the-hood) 1. Hook into the "PageRenderer" API class by fetching the concatenated CSS / JS files, and libraries. 2. If in FE, this is stored within TSFE together with cached data (could be run twice here for non-cached info) 3. Send to the client via `header()` - in BE directly or in FE at the end of the request via a PSR-15 middleware (TYPO3 v10+ only). ToDo ---- [](#todo) - Implement options to also allow to define other resources (fonts/images), e.g. via TypoScript. - Use proper DTOs instead of arrays.
