Google DRIVE API V3 - Get a root folder ID with nodejs

Question

I need to get root folder id and filter folders which have root folder as their parent folder. Using Nodejs and google drive API v3 . This is my code and how I change this code to get root folderId?

 const service = google.drive('v3'); service.files.list({ auth: client2, fields: 'nextPageToken, files(id, name, webContentLink, webViewLink, mimeType, parents)' }, (err, res) => { if (err) { console.error('The API returned an error.'); throw err; } const files = res.data.files; if (files.length === 0) { console.log('No files found.'); } else { console.log('Files Found!'); for (const file of files) { console.log(`${file.name} (${file.id})`); } 

Answer 1

The folder id of the root folder is "root". The file.list method has an option parameter called q which is used for searching.

 service.files.list({auth: auth,
    resource: { parents: [ folderId ] },
    q: "'root' in parents",
    fields: '*',
    spaces: 'drive',
    pageToken: pageToken,
  }

This code is kind of a guess as i dont have the power to test node on this machine.
