LiveStore is a fully-featured, client-centric data layer (replacing libraries like Redux, MobX, etc.) with a reactive embedded SQLite database powered by real-time sync (via event-sourcing).

1. Instant, reactive queries to your local SQLite database (via built-in query builder or raw SQL).
2. Data changes are commited to the store, applied instantly and synced across clients.
3. Change events are persisted locally and synced across clients (and across tabs).
4. Events are instantly applied to the local database via materializers.
5. Query results are reactively and synchronously updated in the next render.
6. The LiveStore sync backend propagates changes to all connected clients.
