I see that Layer0 supports Layer0 Documentation - Svelte and Layer0 Documentation - Sapper.
What about SvelteKit https://kit.svelte.dev/ ?
We do have support for Sveltekit, but as it is currently in beta and changing rapidly so subject to bugs and change. The docs and connector can be updated once they reach v1(which can be tracked here: Issues · sveltejs/kit · GitHub)
WIP/POC Connector (for an earlier-this-year release of sveltekit): layer0-connectors/layer0-sveltekit-connector at main · layer0-docs/layer0-connectors · GitHub
