Access data in JSON format

Question

I'm doing a GET http request for Google Civic's API, where I'm providing an address and receiving members of the U.S. government based on where the provided address is located.

//var options has the host, path, etc.
var req = https.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log(chunk.normalizedInput) //returns 'undefined'
  });
});

chunk is printing this out:

And to my understanding, to access data in normalizedInput, I'd do chunk.normalizedInput, right? Why is it returning undefined?

You retrieve string by stream, you need to wait the end of the stream and parse the string before manipulate object

var req = https.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  var chunks = [];
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
   chunks.put(chunk);
  });
  res.on('end', function () {
   console.log(JSON.parse(chunks.join("")).normalizedInput);
  });
});
