PORT=3001

...

Usage

To start the services, you must run the order-service first, followed by the general-service and payment-service.

1. Start the order-service:

   cd order-service
   npm start

2. Start the general-service:

   cd ../general-service
   npm start

3. Start the payment-service:

   cd ../payment-service
   npm start

Example

The order-service must be running before starting the general-service or payment-service to ensure proper communication between services. After starting the services, you can make API requests to the services using their respective ports.
