• Read the entire question carefully for at least 15 mins, understand it and then code it.
• Commit your code every 30min with a proper commit message to your repository (we will monitor every commit)
• Use Node, Express, Mongo (NEM) for backend.

The task is to create backend for a Air Ticket booking system that allows users to book flights for their desired destinations.

The system should be built using Node.js, Express.js, and MongoDB (NEM) as the backend stack.

• The backend should have the following models
• User Model

{
  _id: ObjectId,
  name: String,
  email: String,
  password: String
}

• Flight Model

{
  _id: ObjectId,
  airline: String,
  flightNo: String,
  departure: String,
  arrival: String,
  departureTime: Date,
  arrivalTime: Date,
  seats: Number,
  price: Number
}

• Booking Model

{
	 _id: ObjectId,
	 user : { type: ObjectId, ref: 'User' },
	 flight : { type: ObjectId, ref: 'Flight' }
}

The following API routes should be developed to achieve the required functionality:

• **Populate all the Object ID’s in the API response.

Important Note :

• Write proper documentation for your API’s clearly specifying what should be the body of your POST API’s, what are the different response API will return. (On your GitHub Readme). You are free to use Postman Documentation or Swagger to implement this.
• Make a video demonstrating that all the API endpoints are working correctly and giving right expected output. Use Postman or ThunderClient to demonstrate this.
• ***Make sure the video is demonstrating working of all the endpoints clearly in detail, failing to do so may after your scores.

• Submit Backend deployed link
• Submit GitHub Repo with proper API documentation Readme
• Submit Recorded Video Drive Link (Make sure it is made public)

• Node
• Express
• Mongo
• Backend API
• Code cleanliness and folder structure.
