This guide explains React’s various state types—local, class, global, navigation, form, and persistent—showing how to manage each with built‑in hooks, Context, libraries such as Zustand, Jotai, React Query, SWR, React Router, TanStack Router, React Hook Form, Formik, and persistence tools like localStorage and redux‑persist.
This tutorial introduces React Query (TanStack Query), explains its motivation, demonstrates how to manage client and server state in React using hooks, Context, useReducer, and provides best practices for caching, optimistic updates, reducing duplicate requests, and performance optimization techniques.
Modern hook-based request libraries such as useRequest, SWR, and react-query transform traditional request flows by encapsulating loading states, caching, refetching, and mutation handling, offering simpler APIs, better user experience, and seamless integration with React’s component model.
This article examines the evolution of frontend request libraries—from jQuery Ajax to modern hook-based solutions like useRequest, SWR, and react-query—highlighting their simplified loading state handling, cache mechanisms, refetching, and mutate features, and comparing their design differences with class components.
