running live-server . is a useful way to view the resultant html files although have more recently moved to python -m http.server 8080 becuase it doesnt need refreshing after page rebuild
old way of doing things
although the html files are only one part of the output
if you need to view ipynb notebooks … although im trying to avoid that … then use jupyter lab for a quick spin up.
the automattion script is watch.py and the code is here
the historical automation (although i dont see why it is of interest) is in the link.
