Navigator

• this application exposes two main APIs
  • a navigation API under /navigate, which simulates a robot navigating through a rectangular grid
  • a persistence API under /navigations, which retrieves records of previously run navigations

To build the application

• run the following command in a terminal window

  ./mvnw clean verify
  

To run the application

• run the following command in a terminal window

  ./mvnw spring-boot:run
  

• to test the navigation API, run the following command in a separate terminal window/tab.

  curl -X POST "http://localhost:8080/navigate" -H "accept: */*" -H "Content-Type: application/json" -d "{ \"roomSize\": [5,5], \"coords\": [1,2], \"patches\": [[1,0],[2,2],[2,3]], \"instructions\": \"NNESEESWNWW\"}"
  

  this should return the result of the operation in the form

  {"coords":[1,3],"patches":1}
  

• to test the persistence API, load either of the following URLs in a web browser:

  • single record url

    http://localhost:8080/navigations/1
    

    where 1 is navigation ID. this should return a single navigation record (request, response) in the form

    {"id":1,"createdDate":[2022,12,13],"request":{"roomSize":[5,5],"coords":[1,2],"patches":[[1,0],[2,2],[2,3]],"instructions":"NNESEESWNWW"},"response":{"coords":[1,3],"patches":1}}
    

  • all records url

    http://localhost:8080/navigations
    

    this should return any navigation records that have been created in the form

    [{"id":1,"createdDate":[2022,12,13],"request":{"roomSize":[5,5],"coords":[1,2],"patches":[[1,0],[2,2],[2,3]],"instructions":"NNESEESWNWW"},"response":{"coords":[1,3],"patches":1}}]
