Svelte Template Directives
@attach (Svelte 5.29+)
The reactive alternative to use: actions. Re-runs when dependencies
change, passes through components via spread, supports cleanup functions.
<script>
import ImageZoom from 'js-image-zoom';
function useZoom(options) {
return (element) => {
new ImageZoom(element, options);
return () => console.log('cleanup');
};
}
</script>
<!-- Re-runs if options changes (use: wouldn't!) -->
<figure {@attach useZoom({ width: 400 })}>
<img src="photo.jpg" alt="zoomable" />
</figure>
