For performance, scale, and effectiveness

This is not a beginner TanStack Query workshop.

This workshop focuses on proven, production-grade patterns for architecting data fetching with TanStack Query, designed for applications that care about performance, scale, and long-term maintainability.

We’ll go beyond APIs and hooks and focus on how the fundamental concepts scale. You’ll see how the same core ideas work for apps with a few hundred users and for systems serving tens of millions of users, without rewriting your mental model every six months.

The patterns in this workshop are battle-tested in real production environments and are designed to improve developer experience, reduce complexity, and make performance predictable.

We’ll also briefly step back and look at TanStack as an ecosystem, showing where other TanStack libraries fit and how to think about them as part of a coherent system, while keeping the main focus firmly on TanStack Query.

The workshop draws directly from experience implementing TanStack Query in real production applications, ranging from small products to platforms serving tens of millions of users. Expect concrete patterns, trade-offs, and failure modes.

You don’t need prior TanStack Query experience, but this workshop assumes you’ve built real applications.

You’ll leave with a clear, scalable mental model for architecting data fetching with TanStack, and patterns you can apply immediately.
