1. Component Organisation

Keep your components focused and single-purpose. A good rule of thumb is that if your component is doing too many things, it's time to break it down into smaller, reusable pieces.

Component organisation is crucial for maintaining a clean codebase. Start by separating your components into logical folders based on their purpose - common components, page-specific components, and feature-specific components.

2. Use Custom Hooks

Custom hooks are a powerful way to extract and reuse stateful logic across components. They help keep your components clean and focused on rendering UI.

When you find yourself repeating the same logic across multiple components, it's time to create a custom hook. This not only makes your code DRY (Don't Repeat Yourself) but also makes testing easier.

3. Proper State Management

Choose the right tool for state management. Not everything needs Redux or Zustand. Sometimes simple useState or useReducer is enough. Evaluate your needs before adding complexity.

Consider the scope of your state: component-level state should stay local, while application-wide state might benefit from a global solution. Context API is great for mid-level state sharing.

4. Performance Optimization

Use React.memo, useMemo, and useCallback wisely. Don't optimize prematurely, but know when these tools can help prevent unnecessary re-renders.

Profile your application first to identify actual bottlenecks. React DevTools Profiler is an excellent tool for this. Focus your optimization efforts where they'll have the most impact.

Conclusion

Following these best practices will help you build more maintainable, performant, and scalable React applications. Remember, the goal is to write code that's easy to understand and modify in the future.

Keep learning, stay updated with the React ecosystem, and don't be afraid to refactor your code as you discover better patterns. Happy coding!
