Thank you for opening the issue.

@andrii-i FWIW in jupyterlab-demo we can drop this extension as jupyterlab-collaboration will ship with its own way of sharing links (jupyterlab/jupyter-collaboration#150) so jupyterlab-link-share will no longer be required for RTC. I started this few days ago on a branch, please see my commits: https://github.com/jupyterlab/jupyterlab-demo/tree/lab-4.0 - the problem is that jupyterlab-collaboration has not been released yet (we can use alpha but I decided to just wait, and since then we got another alpha).

Does the share link feature in jupyter-collaboration work on Binder when there are two servers running with one proxied?

This was also asked in jupyterlab/jupyter-collaboration#150 (comment) but I'm not sure about the status of it.

[krassowski]

It seems to be working fine with binder using https://mybinder.org/v2/gh/jupyterlab/jupyterlab-demo/lab-4.0?urlpath=lab over at jupyterlab/jupyterlab-demo#115. It is a bit unexpected that the link sharing dialog opens by clicking at an icon in top right corner while this extension was adding a menu item (I was looking in the left collaboration panel and all over menus).

when there are two servers running with one proxied?

Is this the usual Binder setup?

Is this the usual Binder setup?

Probably not. At some point it was used for the JupyterLab dev Binder by starting JupyterLav dev mode as a separate server via jupyter-server-proxy. But I don't think this is the case anymore.

@krassowski, @jtpio, thank you for replies and looking into this.
