TanStack Query + Axios Skill

QueryClient

// src/lib/queryClient.ts
export const queryClient = new QueryClient({ defaultOptions: { queries: { staleTime: 30_000 } } });

Axios instance

• src/lib/apiClient.ts: request interceptor attaches Bearer from the auth store; response interceptor on 401 calls the refresh endpoint once, then retries the original request once.

Feature hooks

• useBoardQuery, useMoveTask, useBulkStatus, useInvite live in their feature folder.
• Mutations invalidate/refetch the touched queries; toasts on success/error.

Rules

• REST handles: auth, mutations, uploads, bulk ops. GraphQL handles reads (Apollo).
• No duplicate server state in Zustand.
