We have integrated SpeedkitVimeo 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 SpeedkitPicture and preload the corresponding Vimeo poster in different renditions, so the illusion is perfect for the user and he does not notice anything of the optimized lazy load procedure.


The SpeedkitVimeo is used to initialise Vimeo videos with Vimeo Player-SDK.

The SDK is not part of nuxt-speedkit and will be loaded by an external script.

The url of the Vimeo video must be specified.

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

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