var f

I hope It will useful for you. I uploaded one file from locally and then I added access Token using UUID after that I uploaded into firebase storage.There after I am generating download url. If we hitting that generate url it will automatically downloaded a file.

    const keyFilename="./xxxxx.json"; //replace this with api key file
    const projectId = "xxxx" //replace with your project id
    const bucketName = "xx.xx.appspot.com"; //Add your bucket name
    var mime=require('mime-types');
    const { Storage } = require('@google-cloud/storage');
    const uuidv1 = require('uuid/v1');//this for unique id generation

   const gcs = new Storage({
    projectId: projectId,
    keyFilename: './xxxx.json'
     });
    const bucket = gcs.bucket(bucketName);

    const filePath = "./sample.odp";
    const remotePath = "/test/sample.odp";
    const fileMime = mime.lookup(filePath);

//we need to pass those parameters for this function
    var upload = (filePath, remoteFile, fileMime) => {

      let uuid = uuidv1();

      return bucket.upload(filePath, {
            destination: remoteFile,
            uploadType: "media",
            metadata: {
              contentType: fileMime,
              metadata: {
                firebaseStorageDownloadTokens: uuid
              }
            }
          })
          .then((data) => {

              let file = data[0];

              return Promise.resolve("https://firebasestorage.googleapis.com/v0/b/" + bucket.name + "/o/" + encodeURIComponent(file.name) + "?alt=media&token=" + uuid);
          });
    }
//This function is for generation download url    
 upload(filePath, remotePath, fileMime).then( downloadURL => {
        console.log(downloadURL);

      });
