🚀 Top 5 React JS UI Coding Standards Every Developer Must Know

Whether you're building a small feature or a scalable product, these 5 golden rules will help ensure your UI code in React JS is clean, performant, and team-friendly.

1️⃣ 🎯 Use Feature-Based Folder Structure

Organize your components by feature, not by type.

✅ Easier to scale and navigate
✅ Keeps styles and logic encapsulated

2️⃣ ✨ Always Use Functional Components + Hooks

React is now hook-first! Avoid class components unless absolutely needed.

function UserCard({ name }) {
  return <div>{name}</div>;
}

✅ Clean, concise
✅ Easy to reuse logic with custom hooks

3️⃣ 📦 PropTypes or TypeScript for Prop Validation

Don't skip prop validation — it's your first line of defense against bugs.

Button.propTypes = {
  label: PropTypes.string.isRequired,
  onClick: PropTypes.func,
};

✅ Improves component reliability
✅ Better documentation for other devs

4️⃣ 🎨 Use Modular Styling (CSS Modules, Tailwind)

Avoid global CSS. Use component-scoped styles or utility-first frameworks like Tailwind CSS.

/* Button.module.css */
.btnPrimary {
  background-color: blue;
}

✅ Prevents style conflicts
✅ Encourages reusability

5️⃣ 📚 Linting + Prettier = Clean, Consistent Code

Set up ESLint and Prettier with eslint-plugin-react and eslint-plugin-jsx-a11y.

✅ Auto-format on save
✅ Enforces consistent rules across team

💡 Final Tip: Consistency is key. Set these as part of your team’s coding standards to ensure a predictable and enjoyable dev experience.

🏁 What's Next?

Start by applying these standards in your next project. Create a checklist and enforce consistency through tooling (ESLint, Prettier, Storybook, Tests).
