JavaScript Node.js watch a directory for incoming archive by scp node watch directory for changes,node watch directory,node-sass

I have a task to create a node.js script that listens in a directory for new archive files to arrive and process them.

I see that I can do this with fs.watch.

The files are tar.gz archives, that arrive via scp.

The problem is that the arrival of a new archive file seems to create multiple (the exact number is unpredictable) events in the file-system. The first is a rename, followed by some number of change events.

I need to reliably trigger my processing logic only once, when the archive is finished being transferred. How can this be done?

Additional notes:

  • I am not able to make changes to the system sending the archive, only the system receiving it.
  • I am not considering using elapsed time to guess that the scp event has concluded. That is not reliable.
