Can I use this with Next.js App Router?

Absolutely. The skill includes patterns for 'use client' QueryClientProviders and explains how to integrate with Server Components via prefetching.

Question 3

When should I use TanStack Query vs Zustand?

Use TanStack Query for any data coming from an API (server state). Use Zustand for local-only state like UI themes, shopping carts, or authentication status.

Question 4

How does this handle optimistic UI updates?

It provides a structured template using onMutate, onError, and onSettled to update the UI immediately, handle server failures gracefully with rollbacks, and refetch to ensure data consistency.

Why does this skill recommend a Query Key Factory?

Accepted Answer

A Query Key Factory centralizes your cache keys, ensuring type safety and preventing bugs where different parts of an application accidentally use different keys for the same data.
