Quick question on jupyterlab doc regarding <lab-location>

JupyterLab
#1

This page: https://jupyterlab.readthedocs.io/en/stable/user/urls.html

mentions URLs like e.g.
http(s)://<server:port>/<lab-location>/lab/tree/path/to/notebook.ipynb

what is <lab-location> here ? do I get to configure that ?

I’m asking because we have an architecture in place with an nginx reverse proxy as a frontdesk

this assumes a static partitioning of the URL space, and as part of that we assume jupyterlab-served urls always start with lab/

but this doc suggests otherwise; or am I misreading this ?

Can someone please shed some light on this lab-location thing, I have not found where it is explained in readthedocs

PS.
as a side question, I’ve asked this on gitter earlier, am trying my luck again here
is there a general rule to pick one medium or the other ?

thanks !

I think it depends on how you’re running jupyterlab. If you’re running standalone lab-location will be just /, if you’re using jupyterhub then lab-location will be a combination of where jupyterhub is running and a user-id e.g. /hub/username, and in either case if you’ve got a proxy you might choose to run them under a custom /prefix (can’t remember what the configuration properties are).

OK, thank you for that information, it is helpful :slight_smile:

I don’t use jupyterhub so I take it this is going to be empty for me then;

IMHO it is kind of odd that jupyterlab’s documentation accounts for extra addressing bits that are actually managed by another, optional, layer of tooling ?

#4

It is a recognition that JupyterLab does not exist in isolation, but often is used in conjunction with other tools.

#5

I’ve also been trawling the documentation to see if there is a way to change this setting due to reverse proxy situation… to no avail.

Look in jupyter lab --help-all for the base_url setting. For example: jupyter lab --ServerApp.base_url='/mybaseurl'
