9229 :: How to convert to/from an object to a JsonNode object?

  Is there any way to do this? I find regular objects are easier to work with.

  Just use the % proc.

  To convert an object to json:

  import std / json
  
  type Asd = object
    a: int
  
  echo %* Asd(a: 123)
  Run

  To convert a json Node to an object:

  import std / json
  
  type Asd = object
    a: int
  
  echo parseJson("""{"a": 123}""").to(Asd)
  Run

  Thanks, I thought I was going wrong somewhere because echo seems to know how to print JsonNode objects without any special operator. But echo type(jsonNode) helped with that.

  By the way, echo "knows how" because there is an overloaded $ procedure for JsonNode. In Nim, $ is the equivalent of toString/__str__/etc of other languages
