Complete professional-grade refactoring of the logistics management app:

Architecture:

  • Vite + React 18 + TypeScript setup
  • Component-based architecture with proper separation
  • Custom hooks for business logic (useRates, useCalculator, useToast)
  • Type-safe models and interfaces

Features:

  • Database tab with CRUD operations for shipping rates
  • Calculator tab with ELP margin calculation and history
  • Analytics tab with charts (Recharts) and statistics
  • Data export (JSON/CSV) and import functionality
  • Toast notifications instead of browser alerts
  • Custom confirmation dialogs for destructive actions
  • Debounced search for performance
  • LocalStorage persistence with type safety

UX/Accessibility:

  • WCAG 2.1 compliant with ARIA labels
  • Full keyboard navigation support
  • Focus management in modals
  • Responsive design (mobile-first)
  • Reduced motion support
  • Custom scrollbar styling

Tech stack: React, TypeScript, Vite, Tailwind CSS, Recharts, Lucide
