Installation

1. Clone the repository

   git clone <repository-url>
   cd PR2012/pr201

2. Install dependencies

   npm install

3. Environment Setup

   Create a .env file in the pr201 directory:

   # Database
   DATABASE_URL="postgresql://username:password@localhost:5432/flavor_fusion"
   
   # NextAuth
   NEXTAUTH_SECRET="your-nextauth-secret"
   NEXTAUTH_URL="http://localhost:3000"
   
   # Google OAuth
   GOOGLE_CLIENT_ID="your-google-client-id"
   GOOGLE_CLIENT_SECRET="your-google-client-secret"
   
   # AI APIs (use one or both)
   NEXT_PUBLIC_GROQ_API_KEY="your-groq-api-key"
   OPENAI_API_KEY="your-openai-api-key"

   ⚠️ Security Note: Never commit API keys to version control. Use environment variables and add .env to .gitignore.

4. Database Setup

   npx prisma generate
   npx prisma db push

5. Start the development server

   npm run dev

6. Access the application

   • Main app: http://localhost:3000

   • Specify dietary preferences (vegetarian, vegan, etc.)
   • Click "Generate" to create personalized recipes

2. Ingredient Photo Upload:

   • Use the "FIND INGREDIENT" feature
   • Upload photos of available ingredients
   • Get matching recipe suggestions

3. Recipe Customization:

   • Specify serving sizes
   • Include cooking time preferences
   • Add allergy restrictions

User Account Features

🔧 API Endpoints

Recipe Generation

POST /api/recipe
Body: { "prompt": "recipe description or ingredients" }
Response: { "recipe": "generated recipe content" }

User Management

POST /api/register          # User registration
POST /api/auth/[...nextauth] # Authentication (Google OAuth)
POST /api/forgot-password   # Password recovery

Payment

POST /api/payment           # Handle subscription payments

🧪 Development

Available Scripts

npm run dev      # Start development server
npm run build    # Build for production
npm run start    # Start production server
npm run lint     # Run ESLint

Database Operations

npx prisma studio           # Open Prisma Studio
npx prisma generate         # Generate Prisma client
npx prisma db push          # Push schema changes
npx prisma db pull          # Pull schema from database

🔒 Security Considerations
