Display file upload progress in javascript api

The Dropbox API v2 JavaScript SDK does not offer a way to check the progress on a transfer unfortunately, e.g., for filesUpload. I'll pass this along as a feature request to the team but I can't promise if or when that might be implemented.

If you're using "upload sessions" though, where you upload files in pieces, you can keep track of how much you've uploaded between each piece:

• https://dropbox.github.io/dropbox-sdk-js/Dropbox.html#filesUploadSessionStart
• https://dropbox.github.io/dropbox-sdk-js/Dropbox.html#filesUploadSessionAppendV2
• https://dropbox.github.io/dropbox-sdk-js/Dropbox.html#filesUploadSessionFinish

If you're not already using that, it may be a significant amount or work to switch to it and implement your progress tracking.

Greg-DB  Thank you for the response. Currently, I am using the filesUpload function. Can you please share link for a working example of fileUploadSession.

We have an example of using upload sessions in the JavaScript SDK here: https://github.com/dropbox/dropbox-sdk-js/blob/b2353edeb221ec17b8e70a1d8fd4799e2f1f031d/examples/javascript/upload/index.html#L63

Greg-DB  Yes, I am using the same example, but there is no progress bar code in the example.

Yes, that is just an example of using the upload sessions methods themselves. It doesn't have a progress bar implemented, so you'd need to implement it in your code and hook up your own progress bar. For example, between each filesUploadSessionStart/filesUploadSessionAppendV2/filesUploadSessionFinish call, you could update the state of your progress bar based on the current 'offset' value.
