TypeError: Cannot read property 'statusCode' of undefined

Question

I have done

npm install request

and my code is

const request = require('request');
request('http://www.google.com', function (error, response, body) {
    console.log(response.statusCode);
});

but every time it is throwing a run time error

Answer 1

The response object might be undefined if no response was received so you have to check that it exists before accessing statusCode.

See the example here:

var request = require('request');
request('http://www.google.com', function (error, response, body) {
  console.log('error:', error); // Print the error if one occurred
  console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
  console.log('body:', body); // Print the HTML for the Google homepage.
});

You might not have a response in case there is an error, so make sure to handle the error before trying to handle the response.
