DragDrop Restrictions on drag

[kerry-convery]

In the DragDrop plugin demo on the uppy website the restrictions only seem to work on drop. Is it possible to make them work on drag. What I would like to do is change the drop area border color if a file being dragged isn't allowed to be dropped rather than showing a message after the user has dropped. Can this be done in uppy and if so how?

Note that I have created a custom dragdrop plugin for greater control.

Some of the restrictions can be enforced on drag.

I want to restrict by file type and size. Can either or both of these be enforced during drag? if so how? because setting file type restriction (e.g. Uppy(restrictions: {allowedFileTypes: 'image/*'}); only seems to work on drop.

Hi! Yes, currently we check restrictions when addFile and upload() are called, which happens after drop. To check for restrictions on drag, we’d need to process each file and detect its file type immediately then, and call this logic in Dashboard/DragDrop plugins, as opposed to doing it from Core.

So this is something that needs to be implemented and currently isn't supported out of the box?

[arturi]

Correct.

I’m going to add this to backlog and close for now, thanks!
