How does this skill handle optimistic updates?

The skill provides patterns for optimistic mutations that update the local UI instantly while handling background persistence and server confirmation.

Which sync engines does this skill support?

It provides guidance for several major sync engines, including ElectricSQL (Postgres sync), RxDB (offline-first), and PowerSync.

TanStack DB is a reactive client-side database designed for building local-first applications with sub-millisecond queries and integrated background synchronization.

Is TanStack DB ready for production?

TanStack DB is currently in BETA. This skill helps navigate its current API and best practices while accounting for its evolving nature.

Can I use TanStack DB with existing REST APIs?

Yes, the skill includes specific implementations for using @tanstack/query-db-collection to bridge standard REST APIs with reactive client-side collections.

Database Management

Builds reactive, local-first applications with sub-millisecond live queries and seamless background data synchronization.

About

The TanStack DB skill provides expert guidance for implementing reactive client-side databases using the TanStack DB ecosystem. It helps developers architect local-first applications that support sub-millisecond queries, optimistic UI updates, and robust background synchronization with engines like ElectricSQL, RxDB, and PowerSync. By leveraging this skill, developers can efficiently manage typed collections, implement complex filtering and joins, and handle offline-first data persistence without the overhead of manual state management, specifically during its beta phase.

Key Features

Multi-engine sync support (ElectricSQL, RxDB, PowerSync)
Reactive live queries with incremental updates
Advanced query capabilities including joins, aggregations, and pagination
Optimistic mutations for instant UI feedback
Type-safe collection definitions and schema management
2 GitHub stars

Use Cases

Optimizing data-heavy dashboards with sub-millisecond live query performance
Implementing complex client-side state management using a database-first approach
Building offline-capable web applications with real-time backend synchronization
