Write file and then upload to cloud storage - NodeJS

I'm trying to upload a file to my bucket after it's written but I'm not sure how to do it.

I confirm that code to write the file is ok as I tested it locally and it's working normally.

bucket.upload doesn't seem to work as the file is saved locally. bucket.file.save is also not working

the file is saved at "./public/fileName.xlsx".

When I use:

storage.bucket("bucketName").file("bucketFileName").save("./public/fileName.xlsx")

There's indeed a file been uploaded to the storage, but its content is the path string that I'm passing inside .save()

So to resume my question is: How do I write a file and then upload it to my bucket?

ps: the file is an excel worksheet

If you confirmed that the file is saved locally and just want to upload it to the bucket, you may refer to the sample code below:

const {Storage} = require('@google-cloud/storage');

const storage = new Storage();
// Change to your bucket name
const bucketName = 'bucket-name';

async function uploadFile(path, filename) {
  // Path where to save the file in Google Cloud Storage.
  const destFileName = `public/${filename}`;

  const options = {
    destination: destFileName,
    // Optional:
    // Set a generation-match precondition to avoid potential race conditions
    // and data corruptions. The request to upload is aborted if the object's
    // generation number does not match your precondition. For a destination
    // object that does not yet exist, set the ifGenerationMatch precondition to 0
    // If the destination object already exists in your bucket, set instead a
    // generation-match precondition using its generation number.
    preconditionOpts: {ifGenerationMatch: generationMatchPrecondition},
  };
  // The `path` here is the location of the file that you want to upload.
  await storage.bucket(bucketName).upload(path, options);
  console.log(`${path} uploaded to ${bucketName}`);
}

uploadFile('./public/fileName.xlsx', 'fileName.xlsx').catch(console.error);

Added some comments on the sample code. For more information, you may check this documentation.
