Thanks! this sample is very useful for a quick demo, in particular the upload function.

For those (like me) who rather want to use service account instead of access token, then replace this:

const CLIENT_ID = 'YOUR CLIENT ID';
const CLIENT_SECRET = 'YOUR CLIENT SECRET';
const REDIRECT_URI = 'https://developers.google.com/oauthplayground';

const REFRESH_TOKEN = 'YOUR REFRESH TOKEN GENERATED FROM oauthplayground';

const oauth2Client = new google.auth.OAuth2(
  CLIENT_ID,
  CLIENT_SECRET,
  REDIRECT_URI
);

oauth2Client.setCredentials({ refresh_token: REFRESH_TOKEN });

const drive = google.drive({
  version: 'v3',
  auth: oauth2Client,
});

with this:

  const KEYFILEPATH = path.join(`${__dirname}/../service-account.json`);
  const SCOPES = ['https://www.googleapis.com/auth/drive'];

  const auth = new google.auth.GoogleAuth({
    keyFile: KEYFILEPATH,
    scopes: SCOPES,
  });

  const drive = google.drive({
    version: 'v3',
    auth,
  });

mimeType: 'image/jpg',

bro use ,

` async function uploadFile() {
try {
const response = await drive.files.create({
requestBody: {
name: 'Jai Shree Ram- PDF', //This can be name of your choice
// mimeType: 'image/jpg',
mimeType: 'application/octet-stream'
},
media: {
// mimeType: 'image/jpg',
body: fs.createReadStream(filePath),
},
});

console.log("Uploaded successfully",response.data);

} catch (error) {
console.log(error.message);
}
}

uploadFile(); `

Thanks for it 👍 but I have a question that instead of fs.readStream , can we use buffer directly from multer file in incoming request ?
