As I want to increase my Google Lighthouse score for performance I want to load embedded videos “deferred” with an additional attribute which I tried to add like this in the /site/snippets/blocks/video.php:
<?= video($block->url(), [ ], [ 'async' => true, 'defer' => true ]) ?>
Sadly I can see no difference. How can I do it?
For browsers that already support this: https://web.dev/iframe-lazy-loading/
Otherwise you can use a JS library like: lozad.js/index.html at master · ApoorvSaxena/lozad.js · GitHub
Is this on 3.6 alpha?
If yes, I have a feeling this has something to do with it:
async and defer are not valid iframe attributes?
Yes, I am using alpha 3.6 and have changed the parameters to ‘loading’ => ‘lazy’ but YouTube seems still to be a big problem:
@rasteiner This is indeed the problem and I created a PR for it (tested on my installation): Add loading as an allowed attribute to the video helper by MaluNoPeleke · Pull Request #3654 · getkirby/kirby ·
