Love this.

I was just implementing dragging an SVG element in a Vue app earlier this week, and had to discover pretty much everything the author describes in the article, even in the same order the author describes them, and ended up with pretty much an identical component to do so (except I wrote a composable utility `useDragging` instead of a functional component `<Draggable>`).

Cool! I've tried a directive and tried a component (with slots) but I haven't tried a composable, mainly because I wasn't sure how to set up event handlers that way. (I don't have a lot of experience with composables)

I think a directive is actually a better idea. With a composable I basically just accept a ref of the target element and set up the event handlers directly on it (with useEventListener composables).
