utility.js

 // google cloud stoage 
 let fs                = require('fs');
 const { Storage }     = require('@google-cloud/storage');
 var credentials       = require('../../yourProjectCredentials.json');
 const storage         = new Storage({credentials: credentials});

 const bucketName      = 'pictures';

 const uuidV1          = require('uuid/v1');
 var dir               = './images';



/**
 * Store Image to GCP Buket
 * @param { picture }
 * @returns { picture_url }
 */
class ApplicationUtility{

    constructor(){}

    /**
     * Store Image to GCP Buket
     * @param { picture }
     * @returns { picture_url }
     */

    async storeImageTocloud (picture) {

        let fileNamePic = uuidV1();
        let path2 = fileNamePic + "_picture.jpg";
        let path = dir + "/" + path2;
        var bitmap = new Buffer.from(picture, 'base64');
        fs.writeFileSync(path, bitmap, { flag: 'w' }, (err) => {
            if (err)
                throw (err);
        });
        storage
            .bucket(bucketName)
            .upload(path)
            .then(() => console.log(`${fileNamePic} uploaded to 
             ${bucketName}.`))
            .catch(err => { throw (err) });

        let url = `https://storage.googleapis.com/${bucketName}/${path2}`;
        return url;

    }

}


module.exports = ApplicationUtility;

index.js

  const ImagesStorage              = require('./utility');
  const imagesStorage              = new ImagesStorage();

        //call 
        let picture = body.pic
        let url = await imagesStorage.storeImageTocloud(picture);
        console.log(url)
