All you need is a contract
summary
Claims that using TanStack Query plus Mock Service Worker removes three concrete problems: unmaintainable server‑state code, flaky network tests, and blocked frontend work during sprints. The team deletes manual mocks and Axios mock adapter, writes request handlers (request/response resolvers), and calls setupServer/setupWorker to start interception. Tests stop flaking, no separate mock server is needed, frontend and backend work in parallel, and the sprint finishes earlier with higher confidence and less maintenance.
