Your existing e-commerce system is built using:

Currently, the system supports:

You are required to extend and improve the system without breaking existing features.

Convert the cart into a persistent order.

Create an Order model using Mongoose containing:
- Customer name
- Email
- Cart items (product, quantity, price)
- Total amount
- Order status (Pending, Confirmed, Cancelled)
- Created date
Create a Checkout page:
- Shows cart items
- Shows total amount
- Takes customer name and email
On order submission:
- Save order in MongoDB
- Clear cart session
- Redirect to an Order Confirmation page displaying the Order ID

Implement reusable middleware for validation and authorization.

Create middleware:
- checkCartNotEmpty
  - Prevent checkout when cart is empty
- adminOnly
  - Allow access only if email equals admin@shop.com
Apply middleware properly to relevant routes

Build a simple Admin Orders Panel.

Improve reliability of the system.

Demonstrate real understanding of your code.

Add meaningful comments explaining:
- One route
- One middleware
Fix one existing issue in your project (example):
- Missing async error handling
- Incorrect cart total
- Session-related bug
Be prepared to explain during viva:
- Why sessions are used for cart
- Why middleware is preferred over repeated logic
- Difference between populate() and embedded documents
- How orders differ from carts conceptually
