👉 Description

You don't need to bother with extra attributes on elements (like data-src, only if you want to lazy load background-image), just add the module in nuxt.config.js and that's it 😊

// nuxt.config.js

📝 Updates

background image

lazy-background attribute

<div lazy-background="~/assets/images/background-image.jpg">
  Content
</div>

directiveOnly

If you don't want to use lazy load on every image/video/audio/iframe, set directiveOnly to true and use directive like this (with data-src/data-srcset/data-poster)

<img data-src="image.png" alt="" title="" v-lazy-load>

You don't need to add directive (v-lazy-load) on source elements

<video data-poster="~/assets/images/poster.jpg" v-lazy-load>
  <source data-src="video.mp4" type="video/mp4"> --> without directive
</video>

Manual lazy-load ($lazyLoad)

$lazyLoad is injected, so you can use it everywhere, you just need to call it on parent element or pass an element you want to lazy load. (example below)

data-manual-lazy

If you want to load image/video/audio/iframe only on hover or some other event you can use data-manual-lazy

<!-- 
  with markup like this (mouseenter is on parent element)
  you don't need to pass any element to function
-->
<div class="imageWrapper" @mouseenter="lazyLoadImage">
  <img src="image.png" alt="" title="" data-manual-lazy>
  <img src="second-image.png" alt="" title="" data-manual-lazy>
</div>
 
<!--
  but if you have something like this, then you'll need to
  call another function and to pass elements to it
-->
<div class="imageWrapper">
  <button @mouseenter="lazyLoadImage">Hover me to see the image</button>
  <img src="image.png" alt="" title="" data-manual-lazy>
</div>
methods: {
  lazyLoadImage(e){
    let media = e.target.parentNode.querySelectorAll('[data-manual-lazy]');
    [...media].forEach(m => this.$lazyLoad(m))
  }
}

data-not-lazy

If you don't want to lazy load single element, just add data-not-lazy attribute

<audio controls="controls" data-not-lazy>
  <source type="audio/mpeg" src="audio.mp3">
</audio>

dynamic content

If your content (html) is changing dynamically and you use v-html you can do it like this:

// instead of using v-html="yourHTML" use v-lazy-load="yourHTML"
<div v-lazy-load="yourHTML"></div>
