Handling sharp's output to upload into cloud storage buckets?

Hi,

Not sure what would be the best approach to handle and upload the result of sharp’s transformations. To clarify, I have a google storage bucket that can upload (using google-cloud-node) pointing from a local file location, or more specifically stream from that local file location. example:

bucket.upload('/var/folders/8p/image.png', function(err, file, apiResponse) {
  // Your bucket now contains:
  // - "image.png" (with the contents of '/var/folders/8p/image.png')
  // `file` is an instance of a File object that refers to your new file.
});

or

fs.createReadStream('/var/folders/8p/...')
  .pipe(file.createWriteStream())
  .on('error', function(err) {})
  .on('finish', function() {
    // The file upload is complete.
  });

So my question is: is the best way to write sharp’s result into memory and then upload the file via location path, or is it possible to create a stream of the result and upload the result directly?

Sorry for the novice question in advance, I saw some discussions that were somewhat related, but didn’t really provide any direct solutions.

Hello, you can stream the result.

Using the example at https://github.com/GoogleCloudPlatform/google-cloud-node#preview-2

const remoteWriteStream = gcs
  .bucket('my-existing-bucket')
  .file('zebra.jpg')
  .createWriteStream();

sharp(input)
  .resize(100, 100)
  .pipe(remoteWriteStream);

@taruyar The two and a half year old example code is from https://github.com/googleapis/google-cloud-node so you’ll need to check/ask in that repo.
