TanStack DB 0.5 introduces Query-Driven Sync, a feature that eliminates API sprawl by transforming client-side queries into precise network requests. Instead of creating multiple backend endpoints, developers define queries directly in components, and TanStack DB automatically generates the appropriate API calls. The feature offers three sync modes: Eager (loads entire dataset upfront), On-demand (fetches only requested data using predicate mapping), and Progressive (loads initial batch immediately while syncing remaining data in background). Query-Driven Sync optimizes performance through request deduplication, delta fetching, and intelligent joins, making it particularly effective when paired with sync engines like Electric or PowerSync for real-time data synchronization.
