arcgis javascript api - export map state as JSON: Web_Map_as_JSON

Is there a way to export the current map state as a JSON object, mostly named Web_Map_as_JSON. The JSON specification should be like this.

In other words, it would be convenient to have a function for the Map object, like myMap.Web_Map_as_JSON() that would provide the current state of the MAP.

Answer

This is not directly available through the API. The PrintTask can be used to get the Web_Map_as_JSON.

map.on("load", function(){

  require(["esri/tasks/PrintTask", "dojo/_base/json"], function(PrintTask,  JSON){

    var printTask = new PrintTask();   


    var Web_Map_as_JSON = JSON.toJson(printTask._getPrintDefinition(map));

  });

});
