Building an Employee CRUD Application with React and TanStack Query
Introduction Managing server state in a React application can quickly become complex. You need to handle loading indicators, error states, caching, background refetching, and cache invalidation after mutations. TanStack Query (formerly React Query) solves all of these problems with a declarative, hook-based API.
