Frontend Performance: Optimization Techniques

Introduction

Frontend performance directly impacts user experience and conversion rates. This guide covers essential optimization techniques.

Code Splitting

Reduce initial bundle size by splitting code:

• Use dynamic imports for route-based splitting.
• Lazy load components that aren't immediately visible.
• Monitor bundle size with tools like webpack-bundle-analyzer.

Image Optimization

• Use modern formats (WebP, AVIF).
• Implement responsive images with srcset.
• Use lazy loading for below-the-fold images.
• Compress images without losing quality.

Caching Strategies

• Use browser caching for static assets.
• Implement service workers for offline support.
• Use CDNs for global distribution.

Conclusion

Frontend performance is a continuous process. Monitor metrics, optimize regularly, and prioritize user experience.
