React State Management: Redux vs React Query

When building React applications, managing state effectively is critical. Two popular tools often compared are Redux and React Query—but they serve very different purposes.

Redux is ideal for managing global application state, such as user authentication, UI preferences, or other non-server data. It provides:

• Centralized state management
• Fine-grained control with actions and reducers
• Middleware for handling async logic

React Query, on the other hand, excels at handling server-side state like data fetching and caching. It offers:

• Automatic caching and synchronization
• Background refetching for up-to-date data
• Minimal boilerplate for API integration

Key Differences Between Redux and React Query:

Ultimately, both libraries can coexist in a single project. You could use React Query to handle server-side data and Redux for managing other types of state that don’t fit the server-side use case.
