svelte-disable-preload v0.0.3

svelte-disable-preload

SveltKit provides a client-side router that handles navigation when anchor elements are clicked. It can also be configured to preload data to make your app seem "snappier". It does this by listening for various click, mousedown, mousemove, and touchstart events on the document which will bubble from elements.

For typical "web-app" use, this is no problem. But if you're working with HTML canvas elements and requestAnimationFrame animations, you may not want these extra event handlers being invoked - it can introduce a slight 'juddering' effect and spoil an otherwise smooth animation.

There is an option to disable it but this only disables the behavior from being invoked, i.e. the preloading itself - the event listeners are still there.

This package provides a simple action to apply noop event listeners to an element that prevent the document-level SvelteKit event handlers being invoked.

Usage

Install using your package manager of choice, e.g.

pnpm i svelte-no-preload

Import it into your component and use: it on an element:

<script lang="ts">
  import { disablePreload } from 'svelte-disable-preload'
</script>

<canvas use:disablePreload />

Your canvas interactions should now be slightly smoother.
