Makes an API call to search.property.works/properties/search and calculates the average surface area of the listed properties.
To run:
sbt run
Uses Play JSON for the Json.parse method and the Json.format macro.
In short, the Json.format macro automatically generates a JSON reader/writer from a case class, where the field names and the types match the definition of the case class.
This means extending the project to read more data from the search results only requires adding the new field to the case class.
It can also automatically generate Option and Seq formatters, for nullable fields and arrays respectively.
The scalaj Simplified HTTP library is used for HTTP calls, as it is a simple standalone library.
The main downside of this library is that it is blocking, however, this application will have to block on the result eventually.
This blocking has been pushed into the main method, and the invocation of HTTP within the API Connector is wrapped in a Future.
In a larger/more complicated system, I would prefer to use Play WS. This was not used here as it is a more complicated library, and requires an Akka actor system and other configuration.
Wiremock is used as part of the testing, to run a fake HTTP server for the connector to use.
