The DB connection to Supabase can be made where ever you want it to be. It’s just JavaScript.

In Node, a “module” is generally scoped to a file. So you make a db.ts file and export the instance you create and it functions basically as a singleton. One DB connection per user per session. SvelteKit let’s you choose where to put that. The first place you import it is when it instantiates.

Auth in SvelteKit is trickier than it should be, but there’s a really good technique that I recommend you follow: https://www.captaincodeman.com/re-creating-the-sveltekit-ses...

I believe he uses firebase in his example. But don’t just copy paste, try to understand what is actually happening and why he had to do this workaround. Once you understand how SSR actually works, things get a lot easier.

Stores are a way of storing state on the client side, but to do SSR Svelte has to use stores on its “backend”. The key thing to understand is that stores that are used for SSR are server wide and persistent so you can’t store user specific data in them. There’s a special spot for that kind of state called events.locals.

It’s probably the trickiest area of SvelteKit IMO. I hope they make it better.

I recommend checking out Firebase. Was super easy to get started with for me. And here’s a really easy-to-follow example of using firebase auth with svelte

I just started using firebase too, recommend using this example for inspiration, got me going pretty quick.
