1. Use Lazy Loading for Assets
Defer loading of non-critical assets like images and videos until they're needed. This reduces initial load time significantly.
2. Optimize Critical Rendering Path
Defer non-critical CSS/JS, inline critical CSS, and minimize render-blocking resources to improve first contentful paint.
async or defer attributes for non-critical scripts
3. Optimize Images
Use modern formats (WebP/AVIF), responsive images, and proper compression. Consider next/image from Next.js or native lazy loading.
Optimization Results
- 45% smaller file size
- 40% faster load time
4. Use Performance Libraries
Leverage libraries like Lodash for optimized utility functions, React Query for data fetching, and Wouter for minimal routing. Always check performance benchmarks in DeveloperLibs.
Performance Comparison
| Library | Requests/Sec | Memory Usage | Load Time |
|---|---|---|---|
| Lodash | 850K | 1.2 MB | 23ms |
| Underscore | 680K | 1.5 MB | 38ms |
