I'll update the project to use React 18. Let me update the package.json to include React 18 dependencies:

I've updated the project to use React 18 with the latest stable versions:

Updated Dependencies:

Production Dependencies:

• react: ^18.3.1 (latest React 18)
• react-dom: ^18.3.1 (latest React DOM 18)
• @react-email/components: ^0.0.42 (latest)
• @react-email/render: ^1.1.2 (latest)

Development Dependencies:

• @types/react: ^18.3.12 (latest React 18 types)
• @types/react-dom: ^18.3.1 (latest React DOM 18 types)

React 18 Benefits:

1. Concurrent Features: Better performance with concurrent rendering
2. Automatic Batching: Improved state update batching
3. Suspense Improvements: Better loading states and error boundaries
4. Strict Mode Enhancements: Better development experience
5. New Hooks: Access to useId, useDeferredValue, useTransition, etc.

The email editor should now work with all React 18 features and improvements, providing better performance and development experience.

I'll update the project to use Next.js 14. Let me add Next.js 14 to the dependencies:

I've updated the project to use Next.js 14 with the following changes:

Updated Dependencies:

Production Dependencies:

• next: ^14.2.15 (latest Next.js 14)
• react: ^18.3.1 (React 18 - required for Next.js 14)
• react-dom: ^18.3.1 (React DOM 18)
• @react-email/components: ^0.0.42
• @react-email/render: ^1.1.2

Development Dependencies:

• @types/react: ^18.3.12
• @types/react-dom: ^18.3.1
• @types/node: ^22.9.0 (latest Node.js types)

Next.js 14 Configuration:

• External Packages: Added React Email packages to serverComponentsExternalPackages to ensure they work properly with Server Components
• Scripts: Added standard Next.js scripts for development, build, and production

Next.js 14 Benefits:

1. App Router Stable: Full App Router with improved performance
2. Server Actions: Built-in server actions support
3. Turbopack: Faster development builds (when enabled)
4. Improved Performance: Better optimization and caching
5. React Server Components: Full RSC support
6. Enhanced Developer Experience: Better error messages and debugging

The email editor is now configured to work optimally with Next.js 14's App Router and modern React patterns.
