🔍 React Component Code Review Checklist

🏗️ 1. Component Structure & Design

  • Is the component single-responsibility? (does one thing only)

  • Is it broken into smaller sub-components when it gets too large?

  • Is it a functional component (preferred over class components)?

  • Are props clearly defined and not overly complex?

🧠 2. State Management

  • Is useState used only when necessary?

  • Is state lifted to the appropriate level (not too high, not too low)?

  • Are side effects properly handled inside useEffect?

  • Are there any unnecessary re-renders caused by poor state design? 🔄

🎣 3. Hooks Usage

  • Are hooks called at the top level (not inside loops/conditions)?

  • Is useEffect missing dependency arrays or has incorrect ones?

  • Are custom hooks used to extract reusable logic? 🪝

  • Is useCallback / useMemo used only when truly needed (not premature optimization)?

⚡ 4. Performance

  • Are heavy computations wrapped in useMemo?

  • Are event handlers wrapped in useCallback when passed to child components?

  • Is React.memo() applied to pure child components that don't need frequent re-renders?

  • Are list items rendered with a unique and stable key prop? 🗝️

🔒 5. Props & TypeScript / PropTypes

  • Are all props typed using TypeScript interfaces or PropTypes?

  • Are default values provided for optional props?

  • Is prop drilling avoided in favor of Context or state management tools?

  • Are destructured props clean and readable? ✨

♿ 6. Accessibility (a11y)

  • Do images have meaningful alt attributes? 🖼️

  • Are ARIA roles and labels used where needed?

  • Is the component keyboard navigable?

  • Are semantic HTML elements used (``, ``, ``) instead of plain `

    `s?

🧹 7. Code Cleanliness

  • Is there any dead code (unused imports, variables, functions)?

  • Are magic numbers/strings replaced with named constants?

  • Is the component name PascalCase and descriptive?

  • Is logic kept out of JSX (complex conditions moved to variables)? 🌿

🧪 8. Testability

  • Is the component easily testable (logic separated from UI)?

  • Are side effects isolated so they can be mocked in tests?

  • Does the component avoid hard-coded dependencies that are difficult to inject? 🧬

🎨 9. Styling

  • Is styling consistent with the project's approach (CSS modules, Tailwind, styled-components)?

  • Are there no inline styles unless absolutely necessary?

  • Is the component responsive across different screen sizes? 📱

🔐 10. Security

  • Is user input sanitized before rendering (avoiding dangerouslySetInnerHTML without caution)?

  • Are sensitive values like API keys kept out of the component?

  • Is there protection against XSS attacks? 🛡️

📖 11. Readability & Maintainability

  • Are comments added only where logic isn't self-explanatory?

  • Is the file length reasonable (typically under 200–300 lines)?

  • Is the folder structure logical and consistent with the project? 📂
