  1. Amazing Tutorial. I learned a lot. I actually extended it to upload csv files and adding rows to my table on each file drop. One issue I see in the code which I am trying to fix is that if you drop same file multiple times, it doesn’t display it in the list which is good but it keeps it somewhere in validFiles list and therefore if you delete that file from UI, another version of that file will appear because you tried to dropped it multiple times.

    If you know its fix, please do share with me. Thanks a lot for writing such a detailed tutorial.

  2. const handleFiles = (files) => {
    for (let i = 0; i item.name === files[i].name)
    if (!x) { same as now

  3. hello, very good tutorial,
    but if I want to upload pdf files instead of images, what would be the validation function?
    Thanks!
