Using Leaflet in a Svelte App - the Correct Way - leaflet

Question

I have written a Svelte component that displays a map using Leaflet. The following code of the component works.
I'm just wondering if this is the way to do it, or if there is a "more correct" or "smarter" way? Especially in view of the await import('leaflet'); in loadMap() and the way the CSS is loaded from the CDN in onMount()...
<script>
import { onMount } from 'svelte';
let map;
onMount(() => {
const link = document.createElement('link');
link.rel = 'stylesheet';
link.href = 'https://unpkg.com/leaflet#1.6.0/dist/leaflet.css';
link.onload = () => loadMap();
document.head.appendChild(link);
return () => {
map.remove();
link.parentNode.removeChild(link);
};
});
async function loadMap() {
await import('leaflet');
map = L.map('map').setView([49, 12], 13);
L.tileLayer('https://a.tile.openstreetmap.org/{z}/{x}/{y}.png ', {
attribution:
'Map data © OpenStreetMap contributors, CC-BY-SA',
maxZoom: 18,
}).addTo(map);
}
</script>
<style>
#map {
height: 480px;
}
</style>
<div id="map" />

You could use <svelte:head> to load the css and javascript: According to the docs:
This element makes it possible to insert elements into document.head. During server-side rendering, head content is exposed separately to the main html content.
So the head component would look like this:
<svelte:head>
<link
rel="stylesheet"
href="https://unpkg.com/leaflet#1.6.0/dist/leaflet.css"
integrity="sha512-xwE/Az9zrjBIphAcBb3F6JVqxf46+CDLwfLMHloNu6KEQCAWi6HcDUbeOfBIptF7tcCzusKFjFw2yuvEpDL9wQ=="

<script
src="https://unpkg.com/leaflet#1.6.0/dist/leaflet.js"
integrity="sha512-gZwIG9x3wUXg2hdXF6+rVkLF/0Vi9U8D2Ntg4Ga5I5BZpVkVxlJWbSQtXPSiUTtC0TjtGOmxa1AJPuV0CPthew=="
crossorigin="">
</script>
</svelte:head>
