Using trame with jupyterhub about trame HOT 3 CLOSED

Hi Thomas,

Thanks for your pointers. In the trame documentation that you pointed out, the bottom section is what we recommend nowadays. We are still working on that part (hence the missing explanation that I'm giving you here). On top of that, we are working toward a trame-jupyter-extension to prevent any side connection and use the internal jupyter-comm infrastructure.

But with that approach, we made it flexible so people can configure how that iframe gets generated, and we already have an implementation for jupyter hub.

If I skip most of the bottom section, you will have to do the following in your cell to leverage it.

cone = Cone()
await cone.ui.ready
cone.ui.iframe_builder = "jupyter-hub" # <= set the strategy for building the iframe
cone.ui

or you can

import os

os.environ["TRAME_IFRAME_BUILDER"] = "jupyter-hub"

You may need to do pip install -U trame-client to grab the latest though.

You can see the implementation of those builders, and if you want to expand or add a new one, PRs are indeed welcome.

Good luck with your exploration of trame within Jupyter.

Great! It just works, thanks!

A slightly different approach: pyvista trame's backend is using a server_proxy_prefix str argument to generate the url:
