Implement Efficient Caching Strategy
Medium Impact+12 points estimated
Why It Matters
Critical assets have no cache headers, forcing full re-downloads on repeat visits and slowing LCP by 5.7 seconds.
How to Fix
Configure long-term caching in your deployment by setting cache headers for static assets in nuxt.config.js using 'nitro.routeRules'. Set CSS/JS files to cache for 1 year with immutable directive. Use Nuxt's built-in asset fingerprinting for cache busting.

AI Performance Analysis
This Nuxt/Vue website has poor performance with a score of 64/100, indicating significant room for improvement. The biggest issue is extremely slow loading times, with the Largest Contentful Paint taking 6.7 seconds - nearly triple the recommended target of 2.5 seconds. The main culprits are oversized images (particularly the octocat image that's twice the needed dimensions), 148KB of unused CSS code, and 302KB of unnecessary JavaScript that's blocking the page from rendering quickly. Implementing proper image optimization, removing unused code, and enabling browser caching could dramatically improve load times and boost the performance score by 25+ points.
Other Optimization Recommendations
Remove Unused CSS and JavaScript
High Impact+25 points estimatedWhy It Matters:
151 KiB of unused CSS and 309 KiB of unused JavaScript are blocking rendering and delaying LCP by 2.1 seconds.
How to Fix:
Use Nuxt's tree-shaking to eliminate unused code by enabling 'build.analyze: true' to identify bloated modules. Split large bundles using dynamic imports for non-critical components. Configure PurgeCSS in your nuxt.config.js to remove unused Tailwind classes automatically.
Optimize Images and Add Priority
High Impact+18 points estimatedWhy It Matters:
The LCP image loads slowly without prioritization and uses inefficient formats, delaying LCP by 300ms.
How to Fix:
Add fetchpriority='high' to your main profile image element. Configure Nuxt Image to serve WebP/AVIF formats by adding '@nuxt/image' with providers.cloudinary or similar. Add explicit width and height attributes to prevent layout shifts during image load.
