Bundle Analysis + Performance Audit

Summary

Completed full bundle analysis for Horizon UI Phase 2. All performance targets met.

Key Findings

Metric Value Target Status
Code-split chunks 338 300+ ✅ PASS
Max chunk (gzip) 93.2 KB < 100 KB ✅ PASS
Chunks under 10KB gzip 98% ✅ Excellent

Changes

  • Added PERFORMANCE_AUDIT.md — Complete bundle analysis documentation
  • Added vite-env.d.ts — TypeScript Vite type definitions (fixes build error)

Build Fix

The branch was missing vite-env.d.ts, causing TypeScript to fail on import.meta.env usage. This file is now included.

Bundle Health

  • Main bundle: 93.2 KB gzip (just under 100KB threshold)
  • Largest route chunks: all under 15KB gzip
  • Excellent lazy loading granularity

Conclusion: Bundle is production-ready with excellent code splitting.

- Add PERFORMANCE_AUDIT.md with full bundle analysis
- Add vite-env.d.ts for TypeScript Vite types (fixes build)
- Bundle stats: 338 chunks, max 93.2KB gzip, 0 chunks over 100KB

All performance targets met for Horizon UI Phase 2.
