Where are widgets stored?

[Panda]

Im away from home and only have access to mobile devices, and none of those allow me to create a widget. Can’t drag the html element into the (say) header section. Thats not working in mobile or ‘Desktop mode’ mobile, as the touch screen wont grab the item like a mouse click does.
I was curious if I can create this widget directly as can SSH into my nodebb file system. So question:
Is Widget code stored in the MongoDB database, or is it just a file in the NodeBB file system?
In principle can I create a file that would then be picked up as a Widget. I guess if it is stored as a file, somewhere it must say what category and position on screen it applies to.

@Panda widgets are stored in the Mongo database. I can set the widget up for you if you PM me site details etc.
