I think yuvi wrote the CHP on nginx (https://github.com/yuvipanda/jupyterhub-nginx-chp) when we first wrote CHP, node was the only viable solution to have a dynamic websocket proxy. Nowdays Go, or Python 3 with AsyncIO may be potential contenders. It may be possible to rewrite in Python but time is limitted. I'm unsure about your second question.. run notebook top to bottom ? `nbconvert --to notebook --execute --inplace yournotebook.ipynb` ?
