Implemented a microservice that will expose an API endpoint /calculate that accepts flight records, sorts them, and returns the start and end destinations of the flight path.

Flight Path Tracker

Description

This microservice tracks a person's flight path by sorting through their flight records.

API Endpoint

POST /calculate

Sample Request:

• URL: /calculate
• Method: POST
• Content-Type: application/json
• Body:

  {
    "flights": [
      ["ATL", "EWR"],
      ["SFO", "ATL"]
    ]
  }
  
  

Response:

• Content-Type: application/json
• Body:

   ["SFO", "EWR"]
  

Running the Server

1. Open terminal and navigate to project folder: cd flight-path-tracker/

2. Install dependencies: npm install

3. Start the server: node server.js

4. The server will be running on http://localhost:8080

5. One a new terminal to run the test cases using following curl commands:

curl -X POST http://localhost:8080/calculate -H "Content-Type: application/json" -d '{"all_flights": [["SFO", "EWR"]]}'

curl -X POST http://localhost:8080/calculate -H "Content-Type: application/json" -d '{"all_flights": [["ATL", "EWR"], ["SFO", "ATL"]]}'

curl -X POST http://localhost:8080/calculate -H "Content-Type: application/json" -d '{"all_flights": [["IND", "EWR"], ["SFO", "ATL"], ["GSO", "IND"], ["ATL", "GSO"]]}'

Interesting Ideas and Scalability

• This service can be scaled horizontally by deploying it behind a load balancer.
• Frequently queried flight paths can be cached to improve performance.
• Authentication can be implemented to restrict access to the API.
• Improved error handling to provide more detailed messages.
