State Management in React: A 2024 Perspective

State management in React has evolved significantly. Redux isn't the automatic choice anymore. Here's how to pick the right tool for your needs.

Built-in React State

For many applications, React's built-in state is sufficient:

• **useState**: Local component state
• **useReducer**: Complex local state with actions
• **useContext**: Sharing state without prop drilling

Start here before reaching for external libraries.

When You Need More

Consider external state management when:

• State is accessed by many unrelated components
• You need middleware for async operations
• You want time-travel debugging
• State logic is complex and should be tested separately

Redux Toolkit

Redux remains powerful for large applications. Redux Toolkit (RTK) eliminates boilerplate and includes best practices by default.

Use RTK Query for API caching - it's like React Query but integrated with Redux.

Zustand

Zustand offers a simpler API with less boilerplate. Great for medium-sized apps that outgrow Context but don't need Redux's complexity.

The API is minimal - create a store with state and actions, use it with a hook.

Jotai

Jotai takes an atomic approach. Define atoms (pieces of state) and components subscribe to only what they need.

Perfect for when you need fine-grained reactivity without a centralized store.

Server State

For server data, use dedicated tools:

• **TanStack Query**: Caching, background refetching, optimistic updates
• **SWR**: Similar to TanStack Query, from Vercel

Don't put API responses in Redux or Zustand. Server state tools handle caching and synchronization better.

My Recommendation

• **Small apps**: useState + useContext
• **Medium apps**: Zustand
• **Large apps with many developers**: Redux Toolkit
• **Server data**: TanStack Query

Choose based on your actual needs, not perceived complexity.
