Upload progress about backblaze-b2 HOT 8 CLOSED

You should see a contentLength property in the response of b2.uploadFile() which is in bytes.

I should have been more specific. I'm trying to monitor it in real time in order to build a progress bar.

Not sure you could do that until the module supports multipart uploading.

The upload is a single request to the B2 service with the whole file.

PR is on the way, folks. The PR will add Promise based progress notifications by extending the request object.

#21 adds support for progress notifications via deferred.notify(). If it ever merges in, you'll be able to get upload/download/request progress via the third parameter of .then() as such:

b2.someCommand().then(
  function(res) { /* success handler */ },
  function(err) { /* error handler */ },
  function(info) { /* progress handler (called many times) */ }
);

Multi-part uploads are still not supported. However, support should be coming soon. Keep your eyes open.

Good work again from @crazyscience 👍

The above only worked for v0.9.12 and only worked for download progress reporting. We've changed how progress reporting is handled to take into account both the request (for uploads) and the response (for downloads). As of v1.0.0, a callback function can be passed into relevant b2.method()s. See the README for more information and usage examples. For large, multipart uploads, you will have to write your own code to aggregate across the multiple requests.

This should now be supported with onUploadProgress so I'll close. Please reopen if this is still an issue.
