Remove Unused JavaScript Code
High Impact+20 points estimated
Why It Matters
253 KiB of unused JavaScript is delaying LCP by 150ms and wasting bandwidth on mobile users.
How to Fix
Remove unused Breeze SDK chunks (86KB unused) and Wishlist app code (33KB unused) through Shopify's app settings. Use webpack-bundle-analyzer to identify dead code in custom scripts. Split JavaScript bundles to load only required functionality per page type.

AI Performance Analysis
This Shopify site has poor performance with a score of 60/100, indicating significant user experience issues. The biggest problem is an extremely slow Time to Interactive of 36.8 seconds, caused by excessive JavaScript execution (1.7 seconds) and forced reflows that block the main thread for over 7 seconds total. The site is also suffering from a very slow Largest Contentful Paint of 6.5 seconds due to render-blocking CSS files and oversized images from Instagram that could save over 5MB through modern formats and proper sizing. Reducing unused JavaScript (253KB potential savings), optimizing the large video files (48MB total payload), and fixing the forced reflow issues would dramatically improve both loading speed and interactivity.
Other Optimization Recommendations
Eliminate Forced Layout Reflows
High Impact+25 points estimatedWhy It Matters:
JavaScript is forcing 438ms of layout reflows, directly blocking user interactions and increasing Total Blocking Time to 360ms.
How to Fix:
Optimize the Swiper bundle JavaScript (169ms of reflows) by batching DOM reads/writes or using CSS transforms instead. Update global.js to cache DOM measurements rather than repeatedly querying offsetWidth. Consider replacing heavy carousel scripts with CSS-only solutions where possible.
Optimize Instagram Image Loading
Medium Impact+12 points estimatedWhy It Matters:
5.3MB of oversized Instagram images are unnecessarily large for their 189x189px display size, slowing initial page render.
How to Fix:
Replace Instagram API calls with responsive image srcsets that match display dimensions. Convert poster images to WebP format for 30-40% size reduction. Implement lazy loading for Instagram feed content since it's below the fold.
