This is a tool to import vessel schedules from an external data source and display interesting statistics about these schedules.

• Javascript, NodeJS (Runtime environment)
• Express framework
• NodeJS libraries:
  • axios
  • percentiles
  • dotenv

• NodeJS installed (^12.18.3)
• Basic understanding of running npm/node commands.

1. Clone the GitHub repository to your system.
2. Run npm install from command-line.
3. Create .env file and include API urls, port details like below:

port=5000
vesselsAPI=""
scheduleAPI=""

4. Run npm start

• The top 5 ports with the most arrivals, and the corresponding number of total port calls for each port. Arrivals means the vessel actually stopped at the port [isOmtted flag is set to false]

Endpoint: "http://localhost:5000/mostArrivalsPort"

• The top 5 ports that have the fewest port calls, and the number of total port calls for each port.

Endpoint: "http://localhost:5000/leastPortCalls"

• For each port, the percentiles of port call durations: 5th, 20th, 50th, 75th and 90th percentiles.

Endpoint: "http://localhost:5000/portPercentiles"

• For each vessel, calculate the 5th, 50th and 80th percentiles for the port call delay when the vessel is 14, 7 and 2 days from arrival.
