Upgrade React from 18.2.0 to 19.0.0
Summary
Successfully upgraded the invoice application from React 18.2.0 to React 19.0.0 along with all related dependencies. This major version update required careful dependency management to ensure compatibility across the React ecosystem.
Key Changes:
Migration Approach:
REACT_19_MIGRATION.mdReview & Testing Checklist for Human
3 critical items to verify:
End-to-end authentication flow - Test registration, login, logout, and error cases (invalid credentials, network errors). Verify JWT token handling and session persistence work correctly.
Form validation and submission - Test invoice creation/editing, user registration with validation errors, and ensure react-hook-form integration still works properly with all edge cases.
Production build deployment - Run
npm run buildand deploy to production environment to ensure no build-time or runtime issues that don't appear in development mode.Notes
