Hi everyone, Is there a way to configure Kedro Viz to run on a subpath? http://127.0.0.1:4141/kedro-viz/

Not at the moment, no. Could you please elaborate a little on why you want to do this?

Currently I’m working on a Code Server installation. So Kedro viz would need respect the subpath for that vscode code server installation.

Hi @Jorit Studer , not sure if I understand the question. What’s in http://127.0.0.1:4141/? I have been using GitPod/Codespace and launch viz from there but haven’t run into sub-path issue.

@Nok Lam Chan so internally our ubuntu code server images are deployed under a subpath of the base url. Let’s say https://something.com/code_server/ now if I launch kedro viz it will initially respect the base url path, but when you then click on elements it replaces the subpath with https://something.com/?pipeline_id=xxx instead of http://something.com/code_server/?pipeline_id=xxx

I see! I am not familiar with front-end. Is it possible to configure the sub_path similar to this? @Tynan

no it isn't. we need to edit the way we add our URL params to respect if there's a subpath

or you could use a reverse proxy @Jorit Studer ?

Sadly these are disallowed by policy. But yes normally I definitely could. I ended up wrapping the react component with another react + vite setup then patching the node_module folder. This definitely all works, its just that supporting specifying a subpath would be good feature.

i think if we weren't adding query params to the URL it would work fine. we actually implemented something to ensure this works some time ago, though i think it's being overwritten by the more recent URL params feature

The same issue happens if you run kedro-viz from a notebook server running on a JupyterHub. Then the hub proxy proxies each user to http://something.com/user/lab/. So it is impossible to run kedro viz from a base url!

does it load initially, or not at all?

It actually works (sort of). But if you click on a node to see details, you get nothing. You basically have to click previous page + refresh. Then it works again

@Matthias Roels are you still having this issue?

I think the recent kedro-viz release added sub-domain support which should fix this.

I haven’t upgraded to a more recent version so I will try once I upgraded 😀

yes this was fixed when starting using the command line in jupyter it still wont work, i think, because you can‘t inject the the full endpoint url, we simply monkey patched this part internally
