This project is a backend API for managing products and orders in an e-commerce application. Built with Express and TypeScript, it uses MongoDB for data storage and Mongoose for data modeling. Zod is employed for data validation to ensure integrity.

• Product Management
  • Create, retrieve, update, delete, and search for products.
• Order Management
  • Create, retrieve all orders, and retrieve orders by user email.
• Inventory Management
  • Update product inventory when orders are created.

• Express: Framework for building the API.
• TypeScript: Ensures type safety and better code quality.
• MongoDB & Mongoose: For database operations and data modeling.
• Zod: For schema validation.

       "price": 999,
       "quantity": 1
     }

2. Retrieve All Orders

   • Endpoint: /api/orders
   • Method: GET

3. Retrieve Orders by User Email

   • Endpoint: /api/orders?email=email@example.com
   • Method: GET

• name: string
• description: string
• price: number
• category: string
• tags: array of strings

  • type: string
  • value: string
• inventory: object
  • quantity: number
  • inStock: boolean

• email: string
• productId: ObjectId
• price: number
• quantity: number

Using Zod for request validation:

• Ensure product and order data adhere to the specified structure.
• Provide meaningful error messages on validation failure.

• Handle validation errors with meaningful messages.
• Handle insufficient quantity errors.
• Handle not found errors for products and orders.
• Gracefully handle unknown routes.
