Performance
Use React.memo() strategically, implement virtualization for long lists, optimize images with next/image, leverage code splitting and lazy loading, monitor Core Web Vitals continuously.
Security
Implement XSS prevention through proper escaping, use DOMPurify for user content, secure API calls with proper CORS and authentication headers, never store sensitive data in client-side state.
Scaling
Most React applications benefit from Next.js for SSR/SSG as they scale. Consider micro-frontends for very large applications with multiple teams. Performance optimization becomes critical at 100k+ monthly users.
