First things first, make sure WeWeb has the right plugins for lazy loading. The "Lazy Sizes" plugin is a good pick. You can grab it from WeWeb's plugin marketplace or import it directly if you can't find it there.

Swap out your standard image tags with img tags that use the data-src attribute instead of src. This way, images only load when they're needed.

<img class="lazyload" data-src="your-image-url.jpg" alt="description"/>

Change the image paths in your components to use data-src instead of the usual src attribute. This ensures images load only when they come into view.

<img class="lazyload" data-src="assets/images/lazy-image.jpg" alt="Lazy Loaded Image" />

Include the Lazy Sizes library in your project. You can add it via the CDN in your index.html file.

<script src="https://cdnjs.cloudflare.com/ajax/libs/lazysizes/5.3.0/lazysizes.min.js" async></script>

For SEO, add the noscript tag. This helps search engines crawl the images properly.

<noscript>
  <img src="assets/images/lazy-image.jpg" alt="Lazy Loaded Image" />
</noscript>

For elements with background images, use the data-bg attribute to make sure they load only when needed.

<div class="lazyload" data-bg="assets/images/bg-image.jpg"></div>

After setting up lazy loading, test all your pages thoroughly. Make sure images show up as expected when you scroll. If there are issues, check the console for errors and verify the paths and attributes.

Finally, review and optimize performance. Check loading times and see how lazy loading affects page speed. Tools like Google Lighthouse can help you verify the improvements.

By following these steps, you can efficiently implement lazy loading in WeWeb, boosting your website's performance and user experience.
