Hi Bernard,
Thank you for the claps.
This section will come in one of the next tutorials (possibly 2nd or 3rd). I will address it. Make sure you watch out (subscribe) on github so you receive a notification when I make a new push.
Regarding your ‘duplicates’ issues. This really depends on your business logic. I wasn’t planning on doing so because if you look at Google Drive, Dropbox etc, they will all allow you to upload duplicates.
There is a way to detect duplicates by checking against file name, size and type, but this is still not 100% reliable because technically if you swap out for example, 3 letters in a file, to replace with 5 other but still keep the same file size, your detection will fail. But we can definitely do some validation on a lighter note.
Stick around!
