Svelte + Supabase Framework
"Svupa is a Svelte + Supabase framework to create realtime apps with a single source of truth and optimistic updates. It leverages the power of Supabase to create Svelte stores that are synchronized across clients.
Supabase is an open-source database built on top of PostgreSQL. Svupa synchronizes (part of) the data from this database directly into a Svelte store. Since multiple users can subscribe to the same data, all clients will see the same state.
With Svupa, it's as easy to react to changes in your database as it is to react to changes in a Svelte store - and that's damn easy."
