JSON Serialization

Hank provides first-class support for JSON, ensuring data can flow seamlessly across the Air Gap.

json Namespace

• json_parse(s): Converts a JSON string into Hank data. JSON Objects are converted to Hank Maps.
• json_stringify(val): Converts Hank data into a JSON string.

() {
  json_str = '{"user": "tamas", "id": 123}'
  data = json_parse(json_str)
  
  log_print(map_get(data, "user")) // "tamas"
  
  // Re-serialization
  m = [ "x": 10, "y": 20 ]
  log_print(json_stringify(m)) // '{"x": 10, "y": 20}'
}

Non-Serializable Data

Certain Hank types cannot be stringified because they represent volatile runtime state. Attempting to stringify these will result in Void or an error:

• Opaque handles (e.g. active Regex engines)
• Task definitions
• Error payloads
