Environment Configuration Create a `.env.local` file in your project root: ```env # Firebase Configuration NEXT_PUBLIC_FIREBASE_API_KEY=your_api_key_here NEXT_PUBLIC_FIREBASE_AUTH_DOMAIN=your_project_id.firebaseapp.com NEXT_PUBLIC_FIREBASE_PROJECT_ID=your_project_id NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET=your_project_id.appspot.com NEXT_PUBLIC_FIREBASE_MESSAGING_SENDER_ID=your_messaging_sender_id NEXT_PUBLIC_FIREBASE_APP_ID=your_app_id ``` ### 2. Firebase Project Setup 1. Go to [Firebase Console](https://console.firebase.google.com/) 2. Create a new project or select existing one 3. Enable Authentication (Email/Password, Google) 4. Create Firestore database 5. Set up security rules 6. Get your configuration values ### 3. Firestore Security Rules ```javascript rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { // Users can read/write their own data match /users/{userId} { allow read, write: if request.auth != null && request.auth.uid == userId; } // Diets: users can only access their own match /diets/{dietId} { allow read, write: if request.auth != null && resource.data.userId == request.auth.uid; } // Consultations: doctors and patients can access relevant ones match /consultations/{consultationId} { allow read, write: if request.auth != null && (resource.data.doctorId == request.auth.uid || resource.data.patientId == request.auth.uid); } // Progress: users can only access their own match /progress/{progressId} { allow read, write: if request.auth != null && resource.data.userId == request.auth.uid; } // Orders: users can only access their own match /orders/{orderId} { allow read, write: if request.auth != null && resource.data.userId == request.auth.uid; } // Posts: public read, authenticated write match /posts/{postId} { allow read: if true; allow write: if request.auth != null; } // Comments: public read, authenticated write match /comments/{commentId} { allow read: if true; allow write: if request.auth != null; } } } ``` ### 4. Install Dependencies ```bash npm install # or yarn install ``` ### 5. Run Development Server ```bash npm run dev # or yarn dev ``` ## Usage ### Authentication Flow 1. **Registration**: Users sign up with email/password 2. **Profile Setup**: Complete profile information (name, age, weight, diabetes type, role) 3. **Role Assignment**: Users are assigned roles (patient, doctor, admin) 4. **Access Control**: Different features based on user role ### User Roles - **Patient**: Access to diet plans, exercises, consultations, progress tracking - **Doctor**: Manage patient consultations, create diet/exercise plans - **Admin**: User management, system overview, content management ### Key Features #### Diet Management - Create personalized diet plans - Set nutrition targets (calories, carbs, protein, sugar) - Track meal plans and progress #### Exercise Tracking - Log exercise activities - Monitor completion status - Track progress over time #### Consultations - Book appointments with doctors - Manage consultation status - Upload prescriptions #### Progress Monitoring - Track health metrics - Monitor diet and exercise adherence - Generate progress reports ## API Functions The application provides comprehensive Firestore operations: - **CRUD Operations**: Create, read, update, delete for all collections - **Real-time Listeners**: Subscribe to data changes - **User Management**: Profile creation, updates, role management - **Data Relationships**: Handle references between collections ## Contributing 1.
