I’ve run http servers from my phone to copy files from it. For fun I made CSS for the file list and added an “upload file” button. I never got the php max upload size setting to take effect though. And I never bothered with that cert crap. But you CAN run web servers. I found the php web server worked best.
In godot engine you can put an underscore at the beginning of a variable to tell the linter to calm the hell down about it. But I don’t see why it’s such a crisis in the first place.
