5 Essential React Practices for Real-World Projects

🧱 1. Maintain a Scalable Code Structure

A clean, modular structure is key as apps grow. Suraj’s team uses a feature-based folder system, keeping shared components at the root and feature-specific ones grouped together. Inside components, they follow a strict order:

• Imports → Constants → React Function → useState → Custom Functions → useEffect → Return

Recommended Tools:

• ESLint for linting

• Prettier for formatting

🔁 2. Restrict Unnecessary API Calls

Complex apps often trigger redundant API calls, especially with multiple filters. Suraj learned to optimize useEffect and avoid chaining calls that aren’t needed.

Recommended Tool:

• Lodash for debounce and throttle functions

🔄 3. Use State Management Over Prop Drilling

Passing props through multiple layers (prop drilling) clutters code. Suraj shifted to global state management for cleaner logic and easier debugging.

Recommended Tools:

• Redux for robust state control

• Zustand for lightweight alternatives

📱 4. Pagination for Web, Infinite Scroll for Mobile

Design choices matter. Suraj’s team uses:

• Pagination for web (better SEO, bookmarking)

• Infinite scroll for mobile (fluid UX)

Recommended Tools:

• react-infinite-scroll-component

• Pagination components from MUI and ShadCN

🧪 5. Do Unit Testing Before QA Handoff

Instead of relying solely on QA, Suraj now performs unit tests before handoff, reducing bugs and speeding up release cycles.

Recommended Tool:

• Jest for testing React components

🏁 Conclusion:

These five practices—code structure, API efficiency, state management, responsive design, and testing—are essential for building scalable, maintainable React apps. Suraj’s journey shows how real-world experience sharpens your coding instincts and helps you write better software
