I guess you are using express. You need to configure it to return json format, as explained [here](https://stackoverflow.com/questions/19696240/proper-way-to-return-json-using-node-or-express) — Orelsanpls, Aug 25 '17 at 09:30

In order for your code to return a proper json object you need to specify in the head what are you returning;

response.writeHead(200, {"Content-Type": "application/json"});
var foo = {"a": "b"}
var json = JSON.stringify(foo);
response.end(json);

or if you use express just use:

res.json(json);
