Как сохранить json.stringify ответ в файл?

Question

В настоящее время у меня возникает проблема с проектом node.js, который я делаю прямо сейчас, но я не знаю, как я могу сохранить ответ json.stringify, который я получаю из приведенного ниже кода в файле, откуда я могу получить доступ к данным jSON или есть лучший способ сделать это без его хранения в файле.

Вот мой код:

var watson = require('watson-developer-cloud'); 

var personality_insights = watson.personality_insights({ 
    username: '...', 
    password: '...', 
    version: 'v2' 
}); 

personality_insights.profile({ 
    text: 'I write this to explain why I’ll be holding back my album, 1989, from the new streaming service, Apple Music. I feel this deserves an explanation because Apple has been and will continue to be one of my best partners in selling music and creating ways for me to connect with my fans. I respect the company and the truly ingenious minds that have created a legacy based on innovation and pushing the right boundaries.I’m sure you are aware that Apple Music will be offering a free 3 month trial to anyone who signs up for the service. I’m not sure you know that Apple Music will not be paying writers, producers, or artists for those three months. I find it to be shocking, disappointing, and completely unlike this historically progressive and generous company.This is not about me. Thankfully I am on my fifth album and can support myself, my band, crew, and entire management team by playing live shows. This is about the new artist or band that has just released their first single and will not be paid for its success.', 
    language: 'en' 
}, function (err, response) { 
     if (err) { 
      console.log('error:', err); 
     } else { 
      console.log(JSON.stringify(response, null, 2)); 
     } 
    }); 
}); 

Я использую Watson облако разработчиков выше в моем коде.

Что-то вроде этого?

var watson = require('watson-developer-cloud'); 
var fs = require('fs'); 

var personality_insights = watson.personality_insights({ 
    username: '...', 
    password: '...', 
    version: 'v2' 
}); 

personality_insights.profile({ 
    text: 'blah blah blah', 
    language: 'en' 
}, function (err, response) { 
     if (err) { 
      console.log('error:', err); 
     } else { 
      fs.writeFile(
       './file.json', 
       JSON.stringify(response, null, 2), 
       function(err){ 
        throw err; 
       } 
      ); 
     } 
    }); 
});
