TanStack Query
Async state management. Caching, refetching, and more.
Plain language
What is it?
A tool that manages fetching data from your API or database — handling loading states, caching results, and automatically refreshing stale data.
Why use it at a hackathon?
Instead of manually tracking whether data is loading, cached, or outdated, TanStack Query handles all of that. Your components just ask for data and get it.
Common use
Live resource availability tools, health data dashboards that auto-refresh, food availability apps, civic data explorers with real-time updates.
