Please see the How To guide here. Also please note that no typescript is landed here yet. I write code faster in plain javascript, but plan to convert the code base to typescript a bit later.
Imagine a bright future where humanity will be able to craft buildings on remote planets with robots.
Unfortunately our trusty robot friend Crafty is not so bright, he can only drive forward or rotate left and right. As a Craftnote Engineer your challenge is to write a microservice with Node.js and TypeScript that calculates steering directions for Crafty through a REST API.
The service should run in a Docker container.
Your microservice should provide the following endpoint:
GET /direction?heading=310&target=75...and return result as follows:
{
"direction": "right"
}Here heading is the absolute magnetic heading relative to the north pole of the current planet (we assume the planet has a magnetic field) and target is the absolute bearing to the target.
The response of the service should be a JSON object that contains the direction as a string with values of either left, right, or straight.
The following diagram visualizes these heading and target values. Both numbers are provided as degrees ranging from 0° to 359°.
- Your code should be clean, performant and tested.
- Make sure to validate all inputs and handle errors appropriately.
- Don’t forget to include a
Dockerfilefor the service.
