Team RH Engineer Technical Test

This is a simple command-line Node.js application written in TypeScript.

Running the project

  yarn install
  yarn build
  yarn start

Tests

  yarn test

Testing is achieved using the Jest framework. Currently, only the utils directory is tested which handles data manipulation.

Generally, testing user input is usually more complicated, but a good starting point for this could be a library I found which is node-mock-stdin.

Additionally, integration tests could also be developed.

Biggest challenges

One of the biggest challenges was to do with the descriptions of the data provided. The descriptions don't follow a consistent syntax and so it was difficult to parse the data. I ended up using a few regex patterns that attempt to parse the data in different ways until it finds a method that works.
Some of the descriptions also include HTML tags which I decided to strip out as this could be a security vulnerability if this endpoint was compromised and used on a frontend system.

Final remarks

Thanks for the challenge - it was a fun one! :)
