Real time collaborative binder instance

[Mercury]

Hi there,

I’m fairly new to the jupyter-project and want to create a binder instance, where I can invite my friends, so we can code together in real time. I saw lots of discussions on this topic.

This one gave me a starting point:

What is installed by default with Binder?

I understand that Binder build the environment specified in my repo (e.g., for Python, using requirements.txt) but even with an empty specification, there’s a lot already in the Binder environment. The necessaries for Jupyter Lab, of course, but a lot more too it seems. E.g. I can import ipywidgets without error. What Python packages are installed by Binder by default (e.g., what is its requirements.txt); and what additional Jupyter Lab configuration is preformed by default (e.g., what jupyter …

Here I tried to create such a repo, but unfortunate the shared link won’t sync the changes in real time.
Only if the other person F5 after each change on my side:

GitHub - theRoboxx/jupyter-notebook-for-binder

I also installed jupyter-lab on my machine and started it with jupyter lab --collaborative
(tested for jupyterlab version 3.1.8 and 3.2.5) like written here:

(I cannot post more than two links, so the docs-link will be in the first comment below)

Unfortunate, this didn’t work either, because I couldn’t create a link with the jupyterlab-link-share extension.

Does anyone know if the collaborative-feature works at the moment? And if so, what am I doing wrong in the repo or my jupyter-lab ?

Thanks a lot in advance :).

Yes, it does. Here is one example: JupyterLab 3.2.5 · GitHub
and another one here: README.md · GitHub
