Bundle Size Assessment

Status: ⚠️ EXCEEDS TARGET

  • Current: 1021.07 KB (uncompressed)
  • Target: <250 KB (gzipped)
  • Expected Gzipped: ~300-350 KB (estimated)

The main bundle size concern is the PDF.js library (355 KB), which is necessary for document rendering. This single dependency represents ~35% of the JavaScript payload.


Core Web Vitals Summary

Compliance Status

Metric Status Details
LCP ⚠️ Mixed Home/Contacts/Cameras: Good; Inventory/Maintenance/Expenses: Borderline
FID/TBT ⚠️ Mixed Higher on data-heavy pages (Inventory, Expenses)
CLS Good All pages meet "Good" threshold (<0.1)

Core Web Vitals Targets Met

  • Excellent: CLS (Cumulative Layout Shift)
  • Good: FCP (First Contentful Paint) on most pages
  • Needs Improvement: LCP (Largest Contentful Paint), TBT (Total Blocking Time) on data-heavy pages

Performance Issues & Bottlenecks

1. Large Bundle Size (Critical)

  • Issue: Total JavaScript bundle of 804 KB significantly impacts initial load time
  • Impact: Increases Time to Interactive (TTI) and Total Blocking Time (TBT)
  • Root Cause: PDF.js library (355 KB) required for document viewing
  • Recommendation:
    • Implement dynamic imports for PDF viewer
    • Lazy-load PDF.js only when needed
    • Consider CDN delivery with caching

2. JavaScript Execution (High)

  • Issue: TBT exceeds 100ms on data-heavy pages
  • Impact: Reduced responsiveness during page interactions
  • Root Cause: Complex Vue component rendering, list virtualization not implemented
  • Recommendation:
    • Implement virtual scrolling for long lists (Inventory, Expenses)
    • Break up large component renders with scheduling
    • Use Web Workers for heavy computations

3. LCP Performance (Medium)

  • Issue: LCP slightly exceeds 2.5s target on some pages
  • Impact: User perception of slowness
  • Root Cause: DOM size, render-blocking CSS, JavaScript execution
  • Recommendation:
    • Defer non-critical CSS
    • Optimize hero/header image loading
    • Implement image lazy-loading

4. CSS Bundle Size (Medium)

  • Issue: CSS grows significantly for scoped component styles
  • Impact: Parser/render blocking, network overhead
  • Root Cause: Unoptimized Tailwind generation, component-level CSS duplication
  • Recommendation:
    • Configure Tailwind CSS purging properly
    • Consolidate duplicate utility classes
    • Use CSS-in-JS optimizations
