React Native has become the go-to framework for building cross-platform mobile applications. In this comprehensive guide, I'll share the best practices and patterns I've learned from building multiple production apps.
## Architecture Matters
When starting a React Native project, it's crucial to establish a solid architecture from the beginning. I recommend using a feature-based folder structure that separates concerns and makes the codebase maintainable.
## State Management
For state management, I prefer using Zustand for smaller apps and Redux Toolkit for larger, more complex applications. Both have their place, and choosing the right one depends on your project's requirements.
## Performance Optimization
Performance is key in mobile apps. Some techniques I use include:
- Memoization with React.memo and useMemo
- Lazy loading components
- Image optimization
- FlatList optimization for long lists
## Testing
Always write tests for critical business logic. I use Jest and React Native Testing Library for unit and integration tests.
Building scalable React Native apps requires careful planning, but following these practices will set you up for success.
