Performance, Accessibility & Security

Production-ready patterns for building fast, accessible, and secure React applications.

Performance Optimization

Code-Splitting

Automatic with TanStack Router:

• File-based routing automatically code-splits by route
• Each route is its own chunk
• Vite handles dynamic imports efficiently

Manual code-splitting:

import { lazy, Suspense } from 'react'

// Lazy load heavy components
const HeavyChart = lazy(() => import('./HeavyChart'))
