FitAI Development Progress

Current State

✅ Completed Features

1. Project Structure

• Monorepo setup with separate admin and mobile apps
• Admin: Next.js 14 + TypeScript + Tailwind CSS
• Mobile: React Native + Expo + TypeScript
• Shared utilities and types package

2. Authentication System

• User Registration: Mobile app registration form with validation
• User Login: Secure login with password hashing (bcryptjs)
• Data Storage: In-memory database (demo) with user and client schemas
• Admin Access: User management dashboard with role-based filtering

3. API Endpoints

• POST /api/auth/register - User registration with client creation
• POST /api/auth/login - User authentication
• GET /api/users - User listing with role filtering
• All endpoints include proper error handling and validation

4. Mobile App Features

• Registration screen with form validation
• Login screen with secure credential storage
• Authentication context with protected routes
• Tab navigation (Home, Profile, Attendance)
• User profile display with logout functionality

5. Admin Dashboard Features

• User management interface
• Role-based filtering (All, Clients, Trainers, Admins)
• User cards showing membership details
• Responsive design with Tailwind CSS
• Real-time user data display

Current User Flow

Registration Flow

1. User opens mobile app → Registration screen
2. Fills form (email, password, name, phone)
3. Submits → API creates user + client record
4. Success → Redirect to login screen
5. User can login and access protected tabs

Admin Management Flow

1. Admin opens dashboard → User management section
2. Views all users with role filtering
3. Sees user details: membership type, status, join date
4. Can filter by user role for easier management

Technical Implementation

Database Schema (In-Memory)

User: {
  id, email, firstName, lastName, password, role, phone, createdAt
}
Client: {
  id, userId, membershipType, membershipStatus, joinDate, lastVisit
}

Authentication

• Password hashing with bcryptjs
• JWT-like session storage in mobile (SecureStore)
• Protected routes with authentication context

API Design

• RESTful endpoints with proper HTTP status codes
• Input validation and error handling
• TypeScript interfaces for type safety
