(Again, I need to properly document why.)Īnd I get really frustrated about how over the years it has, and perhaps continues, to break numerous unrelated demos. JupyterLab itself, the next generation Jupyter interface, is a brilliant technology demonstrator, helping push the development of Jupyter server protocols and demonstratring their use.Īnd I hate it as a UI. I don’t use JupyterLab very much, preferring the classic notebook UI for a lot of reasons that I properly need to document, but I was trying to play into that space for folk who do use it. The extension I was loading provided an icon in the JupyterLab launcher so the app could be accessed from that environment as well as from the classic notebook environment. If a repeated request is made for an application that has already been started, the user will be taken directly to it. the jupyter-server-proxy will start an application when it is first requested, so applications do not need to be started when the environment is started applciations are only started when requested.many simple web applications applications do not have any authentication proxying an application behind a Jupyter server means you can make use of the notebook server authenticator to provide a challenge before providing access to the application.All other applications can be proxied along the same path using the same port a container running a Jupyter server and jupyter-server-proxy only needs to expose only a single http port (the one that the notebook / JupyterLab is accessed via).The jupyter-server-proxy idea is useful in several respects: (See some examples here, from which the following list is taken.)
#Jupyterlab dependencies install#
The break was in a launch of one of my own repos, I might add, where I had been trying to install a JupyterLab extension to provide a launcher shortcut to a jupyter-server-proxy wrapped application.įor those of you who don’t know, jupyter-server-proxy is a really, really useful package that lets you start up and access web applications running via a Jupyter notebook server. At the risk of upsetting an overlapping part of the community, I suspect I probably meant to type “I hate JupyterLab”… What the tweet said, and this isn’t true, was how much I hated Jupyter every time I encountered it, showing a screenshot of a failed MyBinder launch breaking on a JupyterLab dependency.
