User Flows

1. Recipe Creation: User logs in → Clicks "Add New Recipe" → Enters recipe details (ingredients, instructions, etc.) → Adds photo → Saves recipe → System calculates nutritional information

2. Recipe Search: User enters search terms → Selects filters (e.g., meal type, cuisine) → Views search results → Clicks on a recipe to view details

3. Meal Planning: User selects "Create Meal Plan" → Chooses duration (e.g., 1 week) → Sets dietary preferences → System generates meal plan → User reviews and customizes plan → Saves or shares plan

   • Implement MongoDB connection
   • Create database models
   • Develop API endpoints
   • Implement authentication

3. Frontend Development (7-10 days)

   • Set up React app
   • Create basic components
   • Implement Redux for state management
   • Develop user interface for all features

4. Integration (3-4 days)

Deployment Strategy

1. Choose a cloud platform (e.g., Heroku, AWS, or DigitalOcean)
2. Set up separate environments for development, staging, and production
3. Use Docker for containerization to ensure consistency across environments
4. Implement CI/CD pipeline using GitHub Actions or GitLab CI
5. Use environment variables for sensitive information
6. Set up automated backups for the database
7. Implement logging and monitoring tools (e.g., ELK stack)
8. Use a CDN for static assets to improve performance
9. Implement SSL certificates for secure connections
10. Conduct regular security audits and updates

Design Rationale

The MERN stack (MongoDB, Express.js, React, Node.js) was chosen for its flexibility and scalability, making it ideal for a recipe management system. MongoDB's document-based structure is well-suited for storing complex recipe data. React's component-based architecture allows for a modular and maintainable frontend. The use of Redux ensures efficient state management as the application grows. The implementation of a RESTful API with Express.js provides a clear structure for backend operations. The focus on vegetarian recipes caters to a growing market trend, while the inclusion of nutritional information and meal planning features adds value for health-conscious users.
