How do I upload a base64 encoded image (string) directly to a Google Cloud Storage bucket using Node.js?

const uuidv4 = require('uuid/v4');
const uuid = uuidv4();

    const os = require('os')
    const path = require('path')
    const cors = require('cors')({ origin: true })
    const Busboy = require('busboy')
    const fs = require('fs')
    var admin = require("firebase-admin");


    var serviceAccount = {
        "type": "service_account",
        "project_id": "xxxxxx",
        "private_key_id": "xxxxxx",
        "private_key": "-----BEGIN PRIVATE KEY-----\jr5x+4AvctKLonBafg\nElTg3Cj7pAEbUfIO9I44zZ8=\n-----END PRIVATE KEY-----\n",
        "client_email": "xxxx@xxxx.iam.gserviceaccount.com",
        "client_id": "xxxxxxxx",
        "auth_uri": "https://accounts.google.com/o/oauth2/auth",
        "token_uri": "https://oauth2.googleapis.com/token",
        "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
        "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/firebase-adminsdk-5rmdm%40xxxxx.iam.gserviceaccount.com"
      }

    admin.initializeApp({
        credential: admin.credential.cert(serviceAccount),
        storageBucket: "xxxxx-xxxx" // use your storage bucket name
    });


    const app = express();
    app.use(bodyParser.urlencoded({ extended: false }));
    app.use(bodyParser.json());
app.post('/uploadFile', (req, response) => {
    response.set('Access-Control-Allow-Origin', '*');
    const busboy = new Busboy({ headers: req.headers })
    let uploadData = null
    busboy.on('file', (fieldname, file, filename, encoding, mimetype) => {
        const filepath = path.join(os.tmpdir(), filename)
        uploadData = { file: filepath, type: mimetype }
        console.log("-------------->>",filepath)
        file.pipe(fs.createWriteStream(filepath))
      })

      busboy.on('finish', () => {
        const bucket = admin.storage().bucket();
        bucket.upload(uploadData.file, {
            uploadType: 'media',
            metadata: {
              metadata: { firebaseStorageDownloadTokens: uuid,
                contentType: uploadData.type,
              },
            },
          })

          .catch(err => {
            res.status(500).json({
              error: err,
            })
          })
      })
      busboy.end(req.rawBody)
   });




exports.widgets = functions.https.onRequest(app);
