Create Order Api

A sample app that implements an ordering system to expose a Restful API to help a Hotel Business to receive a hotel booking details and insert the details in the database.

Tasks

Implementing a NodeJS API to receive a new order and insert it in the Database. Below details are expected in the API:

• Hotel Details (Hotel ID and Hotel Name)
• Check-in Details (Check-in Date and Check-out Date)
• Customer Details (Name, Email and Contact Number)
• Room Details (Room ID, Room Name and Number of Guests)
• Total Amount

MongoDB has been impleneted as the database solution for this API to keep it simple. Although MySQL would be a good alternative to be hosted in AWS RDS

Getting Started

Clone the project repository by running the command below if you use SSH
