Hey I am building a small site (wont be a real site when it's finished), this will be part of a blender add-on where you can import midi file and will get converted to svg using a npm package. but I need a way to dynamically be able to select a midi file from a folder. there will only be one midi file (input) in there and one svg (output) file. I won't know the name of the file but I do know the extention. I rather don't pull a backend into this since it's seems something small... I am hoping there is a solution for this..
