React State Management in 2025
From useState to server state, a practical overview of modern React state patterns.
State management in React has evolved significantly. Here is how we approach it today.
Local State
For most components, useState and useReducer are sufficient. Do not reach for a global store until you have a real cross-component state sharing need.
Server State
Tools like TanStack Query handle caching, deduplication and background updates. Treat server state differently from client state.
URL State
Search params and route state belong in the URL. This makes your app shareable and bookmarkable.
When to Go Global
Use a global store like Zustand only when multiple distant components need to share and update the same state.
