Vite React Best Practices

A senior-level guide for building production-ready React Single Page Applications (SPAs) with Vite.

When to Apply

Reference these guidelines when:

• Setting up a new Vite + React project
• Configuring build pipelines and CI/CD for SPAs
• Troubleshooting production build or caching issues
• Refactoring React components for performance

Rule Categories

1. Vite SPA Deployment (CRITICAL)

• Static Rewrites - Mandatory for client-side routing.
• Caching Strategy - Immutable assets, no-cache index.html.
• Build Validation - Preview before push.
• Environment Variables - VITE_ prefix and security.

2. React Core Performance

• Route Splitting - Lazy load pages.
• Server State - Use React Query/SWR.
• Memoization - When to use useMemo/useCallback.
• Image Optimization - CLS prevention.

3. Architecture & Cleanup

• Colocation - Feature-based structure.
• Anti-Patterns: Import from Dist - Avoid bundling twice.
• Troubleshooting - Common Vite fixes.
