Send attachments through Chat
Still new to NodeBB, but I think the chat is handled by Redis/MongoDB. While you can store files in MongoDB using GridFS, I would think a great way to tackle that would be to have the plugin upload the file to storage (like AWS S3) and then include in the body of the message a link to the downloaded file. Permissions could be set at upload to only allow members of the chat access to the file.
I would also be very interested in this feature!
