Google Drive authentication and file manipulation


Google Drive


  1. Activate Google Drive API in Google Console https://developers.google.com/drive/api/quickstart/nodejs?hl=fr

  2. Create a OAuth Desktop Application credentials https://console.cloud.google.com/apis/credentials

  3. Download the Client OAuth file and copy into your zenv with the name oauth2-drive.keys.json

open .

Install NPM dependencies

npm install googleapis@105 @google-cloud/local-auth@2.1.0 --save

Manipulate your Drive files

Run the block one time to save your authentication state (refresh_token) into token.json

//exec: node
const path = require('path');
const { google } = require('googleapis');
const {authenticate} = require('@google-cloud/local-auth');
const fs = require('fs');

const drive = google.drive('v3');

const TOKEN_PATH = path.join(__dirname, "token.json")
const CREDENTIALS_PATH = path.join(__dirname, 'oauth2-drive.keys.json') // this is your credentials file previously downloaded
const SCOPES = ['https://www.googleapis.com/auth/drive.file']

// Methods utilities to authorize and save credentials
async function loadSavedCredentialsIfExist() {
  try {
    const content = fs.readFileSync(TOKEN_PATH);
    const credentials = JSON.parse(content);
    return google.auth.fromJSON(credentials);
  } catch (err) {
    return null;

async function saveCredentials(auth) {
  const content = fs.readFileSync(CREDENTIALS_PATH);
  const keys = JSON.parse(content);
  const key = keys.installed || keys.web;
  const payload = JSON.stringify({
    type: 'authorized_user',
    client_id: key.client_id,
    client_secret: key.client_secret,
    refresh_token: auth.credentials.refresh_token,
  fs.writeFileSync(TOKEN_PATH, payload);

async function authorize() {
  let auth = await loadSavedCredentialsIfExist();
  if (auth) {
    return auth;
  auth = await authenticate({
    scopes: SCOPES,
    keyfilePath: CREDENTIALS_PATH,
  if (auth.credentials) {
    await saveCredentials(auth);
  return auth;

// load authorization
const auth = await authorize();

// Work with Drive API
const filePath = path.join(__dirname, "FILE_TO_UPLOAD.png");

 const response = await drive.files.create({
    requestBody: {
        name: 'FILE_TO_UPLOAD.png', //file name
        mimeType: 'image/png',
    media: {
        mimeType: 'image/png',
        body: fs.createReadStream(filePath),
// report the response from the request

  const response = await drive.files.delete({
            fileId: '1LnPv2cwtZB1JG9l0KAwtJyG7CPLZkZDg',// file id
        console.log(response.data, response.status);
