Client-Only Component in SvelteKit

TODO: collapasable, copyable, download, etc

In SvelteKit, how can I make my component run client side only?In SvelteKit, if you need a component to run only on the client side, you can use Svelte's special <svelte:component> tag along with dynamic imports and the onMount lifecycle function. The idea is to dynamically import the component inside the onMount function, which only runs in the browser, ensuring that the component is loaded and executed only on the client side. Here's a step-by-step guide on how to achieve this:

1. Dynamic Import within onMount: Use the onMount function to dynamically import the component. This ensures that the component is only imported and rendered when the application is running in the client's browser.

2. Placeholder Rendering: Initially, you might want to render a placeholder or nothing until the component is loaded to manage the user's expectations or the layout shift.

Here is a basic example to demonstrate how you can implement this:

<script>
  import { onMount } from 'svelte';
  let ClientOnlyComponent;

  onMount(async () => {
    const module = await import('./ClientOnlyComponent.svelte');
    ClientOnlyComponent = module.default;
  });
</script>

<!-- This is where your client-only component will be rendered -->
<svelte:component this={ClientOnlyComponent} />

<!-- Optional: Placeholder or loading indicator -->
{#if !ClientOnlyComponent}
  <p>Loading...</p>
{/if}

In this example, ClientOnlyComponent.svelte is the component that you want to run on the client side only. The onMount function ensures that the component is loaded dynamically when the SvelteKit application is running in the browser, not during server-side rendering or static site generation.

This approach allows you to seamlessly integrate client-only components into your SvelteKit applications, which is particularly useful for components that rely on browser APIs or need to interact with the DOM directly, which is not available during server-side rendering.
