Performance Optimization Techniques for Nuxt Applications

Introduction

Performance is crucial for user experience and SEO. Nuxt 3 provides many built-in optimizations, but there are additional techniques you can implement to further improve your application's performance.

Code Splitting

Nuxt 3 automatically implements code splitting, but you can optimize it further:

• Use dynamic imports for heavy components
• Implement route-based code splitting
• Optimize bundle size with tree shaking

Image Optimization

Images often account for the largest portion of page weight:

• Use the Nuxt Image module
• Implement lazy loading
• Choose appropriate image formats (WebP, AVIF)
• Optimize image sizes for different devices

Caching Strategies

Implement effective caching to improve performance:

• Browser caching for static assets
• CDN caching for global content
• API response caching
• Service worker caching for offline support
