Which piece of data is the best fit for a server-state library like TanStack Query?

The current user's list of orders loaded from the API

The user's orders from the API are the best fit. Orders live on the backend. The client only holds a cache, which needs fetching, invalidation and refetching. That is what server-state libraries do.

The search box text is the tempting wrong answer, because it is often used to fetch data. But the text itself is client state. The sidebar, the search text and the theme are all UI state that the browser owns. useState, context or a client store handles them fine.
