Best Practices
Regardless of which state management tool you choose, following certain best practices ensures your React Native application remains maintainable, performant, and easy to debug as it scales.
1. Keep State as Local as Possible
Only lift state to a global store when it is genuinely needed by multiple, unrelated components, avoiding unnecessary complexity for simple, component-specific data.
2. Normalize Complex Nested Data
Store relational data in a normalized, flat structure rather than deeply nested objects, making updates and lookups significantly more efficient.
3. Separate Server State from Client State
Use tools like RTK Query or React Query for server-derived data, and reserve Redux or Context for purely client-side application state like UI preferences.
4. Avoid Storing Derived Data
Compute derived values, such as a filtered list or a total price, using selectors or memoized functions instead of storing duplicate, potentially out-of-sync copies in state.
5. Use Consistent Naming Conventions
Follow consistent naming patterns for actions, slices, and selectors across your codebase, making it easier for team members to navigate and understand the state architecture.
6. Write Tests for Reducers and Selectors
Since reducers are pure functions, they are straightforward to unit test, helping catch state management bugs early before they reach production.
7. Document Your State Shape
Maintaining clear documentation or TypeScript types for your global state shape helps onboard new developers and prevents confusion as the application grows.
Conclusion
Following these state management best practices, regardless of the specific library chosen, results in a more maintainable, scalable, and bug-resistant React Native application over the long term.
