How to print object in Node JS

rated 0 times [ 134] [ 3] / answers: 1 / hits: 105665 / 8 Years ago, thu, august 4, 2016, 12:00:00

In the below code (running on Node JS) I am trying to print an object obtained from an external API using JSON.stringify which results in an error:

TypeError: Converting circular structure to JSON

I have looked at the questions on this topic, but none could help. Could some one please suggest:

a) How I could obtain country value from the res object ?

b) How I could print the entire object itself ?

  http.get('http://ip-api.com/json', (res) => {     

    console.log(`Got response: ${res.statusCode}`);

    console.log(res.country)  // *** Results in Undefined

    console.log(JSON.stringify(res)); // *** Resulting in a TypeError: Converting circular structure to JSON



    res.resume();

  }).on('error', (e) => {

    console.log(`Got error: ${e.message}`);

  });

By using the http request client, I am able to print the JSON object as well as print the country value. Below is my updated code.

var request = require('request');

request('http://ip-api.com/json', function (error, response, body) {

  if (!error && response.statusCode == 200) {

    console.log(response.body);    // Prints the JSON object

    var object = JSON.parse(body);

    console.log(object['country']) // Prints the country value from the JSON object

  }

});
