Question

I have written API and got to upload in Heroku server. When I push the data in the Heroku after changes then all the images are gone. I don\'t know why they were not shown.

If You want to upload the image to Google Drive using npm package, You can try it that way:

• Go to that site: Turn on Google Drive API, create credentials.json file, download it and move to working directory.
• Add googleapis package: yarn add googleapis
• Create two functions: authorize and uploadFile.
• Read Your credentials from credentials.json file, call authorize and invoke uploadFile as a callback.

Code to upload the image:

const fs = require('fs');
const { google } = require('googleapis');

// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];
const TOKEN_PATH = 'token.json';

/**
 * Create an OAuth2 client with the given credentials, and then execute the given callback function.
 */
function authorize(credentials, callback) {
  const {client_secret, client_id, redirect_uris} = credentials.installed;
  const oAuth2Client = new google.auth.OAuth2(
      client_id, client_secret, redirect_uris[0]);

  // Check if we have previously stored a token.
  fs.readFile(TOKEN_PATH, (err, token) => {
    if (err) return getAccessToken(oAuth2Client, callback);
    oAuth2Client.setCredentials(JSON.parse(token));
    callback(oAuth2Client);
  });
}
/**
* Describe with given media and metaData and upload it using google.drive.create method()
*/ 
function uploadFile(auth) {
  const drive = google.drive({version: 'v3', auth});
  const fileMetadata = {
    'name': 'photo.jpg'
  };
  const media = {
    mimeType: 'image/jpeg',
    body: fs.createReadStream('files/photo.jpg')
  };
  drive.files.create({
    resource: fileMetadata,
    media: media,
    fields: 'id'
  }, (err, file) => {
    if (err) {
      // Handle error
      console.error(err);
    } else {
      console.log('File Id: ', file.id);
    }
  });
}

fs.readFile('credentials.json', (err, content) => {
  if (err) return console.log('Error loading client secret file:', err);
  // Authorize a client with credentials, then call the Google Drive API.
  authorize(JSON.parse(content), uploadFile);
});
