Ask HN: I'm running an Open Street Map tile server. How can I create .osm files?

Hi Guys,

Thanks in advance - I am running a self hosted Open Street Map tile server and can access it and fly around the map in the browser to my hearts content.

I would however like to be able to 'download' or otherwise produce on the server '.osm' files based on either the map view, or some supplied co-ords - or any way really.

I have looked through switch2osm and leaflet etc and I can't see what I'm looking for.

If anyone can send a link my way to what I'm looking for I should be forever grateful.

Thanks again!
