@svackages/lazy-action v1.0.2

Svelte action lazy load

This action uses the IntersectionObserver to load images or iframes lazily.

It will replace data-src with src.

And of course it is fully typed 😉

How to use

Install

npm i @svackages/lazy-action

Use in svelte component (svelte-kit only)

<script>
    import lazy, {newObserver} from '@svackages/lazy-action';

    // You can overwrite the standard
    // obeserver with the values you want
    newObserver({
        rootMargin: '70px 0px',
    });
</script>

<img
