🚀 Setup Instructions

1. Environment Variables

-Ensure you create a .env file in the root of your backend directory to store the following values:

# MongoDB connection string
DATABASE_URL=mongodb://<username>:<password>@<cluster-url>/<database-name>

# JWT Secret Key for signing tokens
JWT_SECRET=your_jwt_secret_key

2. Database Setup

• Set up a MongoDB database with the following collections:
  • User
  • Products
  • OrderHistory

Sample Data:

// User Collection
[
  {
    "_id": "6705805b10383e99a0ca601e",
    "name": "John Doe",
    "email": "johndoe@example.com",
    "password": "hashed password",
    "age": 69,
    "creditCardNumber": "1234-5678-9012-3456"
  },
  {
    "_id": "6705806b10383e99a0ca6f86",
    "name": "Jane Smith",
    "email": "janesmith@example.com",
    "password": "hashed password",
    "age": 34,
    "creditCardNumber": ""
  }
]

// Products Collection
{
  "_id": "670585828f5aa89913c4e49b",
  "name": "Aspirin",
  "price": 5.99,
  "stock": 126,
  "companyName": "HealthCorp"
}

// OrderHistory Collection
{
  "_id": "67058bfb8f5aa89913c4e4ab",
  "userId": "6705805b10383e99a0ca601e",
  "productId": "670585828f5aa89913c4e49b",
  "quantity": 2,
  "orderDate": "2024-10-01T12:00:00.000Z",
  "stockAtOrder": 148
}

• Note: Jane Smith does not have a credit card number as per the project requirement.
• Note: userId and productId of OrderHistory collection is refernce to the unique id of User and Product db.

3. Key Database Functionalities

• Email Uniqueness: An index is added to ensure email uniqueness during the database setup.
• Profile Updates: Users can update details such as name, age, and credit card number. Email and password updates are restricted (would require email verification for security and users are predefined as of).
• Credit Card Prompt: If a user’s credit card number is missing, the application will prompt for it during product purchases.
• Order History: Displays the complete order history for the logged-in user, including the stock level at the time of each order.
