Ways to use Lordicon in a sveltekit project

+layout.svelte

<script lang="ts">
	// Best option
	//
	// onMount(() => {
	// 	let lottieInstance: any;

	// 	// eslint-disable-next-line @typescript-eslint/no-floating-promises
	// 	void (async () => {
	// 		try {
	// 			const lottie = (await import('lottie-web')).default;
	// 			const { defineElement } = await import('@lordicon/element');
	// 			defineElement();

	// 			// If you later create an animation, capture the instance:
	// 			// lottieInstance = lottie.loadAnimation({...});
	// 		} catch (err) {
	// 			// eslint-disable-next-line no-console
	// 			console.warn('could not load lottie / lordicon client libs:', err);
	// 		}
	// 	})();

	// 	// synchronous cleanup function (must be sync)
	// 	return () => {
	// 		if (lottieInstance?.destroy) lottieInstance.destroy();
	// 	};
	// });

	// Another alternative is to use IIFEs
	//
	onMount(() => {
		// Use promise chaining to avoid an async function that might return a Promise
		// (Svelte's onMount should return a synchronous cleanup function).
		import('lottie-web')
			.then((m) => m.default)
			.then(() => import('@lordicon/element'))
			.then(({ defineElement }) => defineElement())
			.catch((err) => {
				// Fail gracefully in environments where these client-only libs can't load
				// (e.g., during certain dev-tooling runs). Keep a console warning for debug.
				// No runtime-critical behavior depends on these imports here.
				// eslint-disable-next-line no-console
				console.warn('could not load lottie / lordicon client libs:', err);
			});
	});

	// Another alternative is IIFEs
	//
	// onMount(() => {
	//   (async () => {
	//     try {
	//       const lottie = (await import('lottie-web')).default;
	//       const { defineElement } = await import('@lordicon/element');
	//       defineElement();
	//       // if you need the lottie instance later, store it (example below)
	//       // (globalThis as any).__LOTTIE__ = lottie;
	//     } catch (err) {
	//       // eslint-disable-next-line no-console
	//       console.warn('could not load lottie / lordicon client libs:', err);
	//     }
	//   })();
	// });
