Speed up TYPO3 rendering via HTTP/2 Server Push
This TYPO3 extension fetches all CSS and JS resources that are used for a page-rendering and sends additional HTTP/2 Headers "Link" for each resource resulting in a faster first contentful paint for TYPO3 CMS.
This extension currently runs on TYPO3 v10, TYPO3 v11 and TYPO3 v12, and needs PHP 7.4 or higher.
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).
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.
- Hook into the "PageRenderer" API class by fetching the concatenated CSS / JS files, and libraries.
- If in FE, this is stored within TSFE together with cached data (could be run twice here for non-cached info)
- 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).
- Implement options to also allow to define other resources (fonts/images), e.g. via TypoScript.
- Use proper DTOs instead of arrays.
