You can access the database from anywhere (client and server depending on your config). I use nextjs so many of my database calls are in Next serverless functions. However, I’ll probably explore moving some of that logic to supabase functions to keep them as close as possible to the database, but I haven’t wanted to move to deno. When you access supabase on the server you can either use their PostgREST features (basically an autogenerated REST API on top of your db which the supabase clients use), or just access Postgres directly though a typical pg lib
