Jak zapisać odpowiedź json.stringify do pliku? - json, node.js, ibm-watson

Obecnie mam problem z węzłem.projekt js, który teraz wykonuję, ale nie wiem, jak mogę zapisać odpowiedź json.stringify, którą otrzymuję z poniższego kodu w pliku, z którego mogę uzyskać dostęp do danych jSON lub czy istnieje lepszy sposób, aby to zrobić bez przechowywanie w pliku.

Oto mój kod:

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.",

}, function (err, response) {
if (err) {
console.log("error:", err);
} else {
console.log( JSON.stringify(response, null, 2) );
}
});
});

Używam powyższej chmury programistów Watson w moim kodzie.

Coś takiego?

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;
}
);
}
});
});
