Why Your Lovable App Is Slow
AI-generated code prioritizes functionality over performance. Here's how to fix that.
1. Bundle Size Analysis
AI apps often import entire libraries. Check your bundle:
"Analyze the bundle size. Identify large dependencies and suggest lighter alternatives. Implement code splitting with React.lazy for routes."
2. Image Optimization
Unoptimized images are the #1 performance killer. Prompt:
"Optimize all images: use next-gen formats (WebP), add lazy loading, set explicit width/height, use responsive srcset. Add a blur-up placeholder effect."
3. Lazy Loading
Don't load everything upfront:
"Implement React.lazy for all page components. Add Suspense with skeleton loaders. Lazy-load images below the fold with Intersection Observer."
4. Database Query Optimization
Supabase queries can be chatty. Fix with:
- Single queries instead of N+1 patterns
- Proper indexes on filtered columns
- Pagination for lists
5. Caching Strategy
Implement a caching layer:
- React Query for API calls
- SWR for real-time data
- Service Worker for static assets
Expected Results
After these optimizations, expect:
- Lighthouse score: 90+
- FCP under 1.5s
- TTI under 3s
