Implementation with SvelteKit

Hey everyone.

I am working on an idea I had for ActivityPub implementation. The initial functionality is supposed to be dead simple with only one user and the ability to post messages. I am using SvelteKit, Lucia Auth, and Drizzle ORM with SQLite db for now. However, I’m not a developer per se, so I’m having trouble figuring out how to implement AP on SvelteKit app, I’m assuming it shouldn’t be that difficult.

Anyways, can someone help me with ActivityPub setup on SvelteKit app? More specifically, how would you go about setting up the endpoints, webfinger, and signing functionality?
