BoosterYoutube

We have integrated BoosterYoutube as an example to show how iFrame content must be integrated in a performance-optimized manner. For this purpose, a separate IntersectionObserver has been implemented, which detects a longer dwell time of the component in the viewport. The iFrame is initialized only after a positive detection. This prevents immense data from having to be loaded when simply scrolling through the page. So that no empty space is visible to the user, we use the functionality of the BoosterPicture and preload the corresponding Youtube poster in different renditions, so the illusion is perfect for the user and he does not notice anything of the optimized lazy load procedure.

Usage

The BoosterYoutubeis used to initialise Youtube videos with Youtube Iframe-API.

The Youtube Iframe-API is not part of nuxt-booster and will be loaded by an external script. Learn more

The url of the Youtube video must be specified.

The BoosterPicture is used for the poster, so the generation of the poster is automated, you can define the image sources with posterSources (What is posterSources?).

Important: For using BoosterYoutube do not disable @nuxt/image via disableNuxtImage.
