build a full-stack hostel management system called "KAMMA HOSTEL" with the following requirements: Frontend: - Next.js with TypeScript - Responsive design for all screen sizes - Modern color styles Backend: - Node.js with TypeScript - MongoDB database - RESTful API - User authentication and authorization - File uploads with Cloudinary integration - Email notifications - Production-ready with error handling and security Key Features: - Admin Features: - Dashboard - Student registration management (comprehensive details including personal, academic, family info) - Student management (view, update, delete, block/unblock) - Leave request approval/rejection - Search and filtering options - Warden management - Gallery management - Public pages management - Data export (year-wise, campus-wise) - Settings and backup - Warden Features: - Attendance management - Limited student data changes - Leave request approval/rejection - Fine management - Student Features: - Login with email/password - View personal details (read-only) - Leave request submission - Attendance tracking The user specifically asked me to start with the backend code first and make it comprehensive with all features and error-free code. Since this is a complex full-stack application with multiple user roles and extensive features, I should use the TodoManager to break this down into manageable tasks. This is definitely a multi-step project that requires: - Backend API setup - Database models and schemas - Authentication system - Admin dashboard - Warden interface - Student interface - File upload integration - Email notification system Let me start by creating a todo list to organize this complex project.a7:T3cbe8,[V0_FILE]json:file="package.json" isMerged="true" { "name":
