Responses on Vapor

NStack can be used to store JSON responses. To make use of this feature you can use the ResponseController.

let nstack = try NStack.makeService(for: req)
nstack.application.response[42].do { (response: Response) in

This gets the unmodified NStack Response with your JSON data in an object keyed by data, eg.:

{"data":{"myJSONData":"Starts here"}}

Alternatively you can decode your JSON object like so:

nstack.application.response[42].do { (response: [String: String]) in

This would yield your Decodable object, in this case our dictionary: ["myJSONData": "Starts here"].
