I want to run Open Web UI under a configurable Base URL. e.g. http://localhost:8080/MY_CUSTOM_BASE

It would be nice to have a env var for this.

I thought it might be possible to do it via the WEBUI_URL env var, but it seems to be mostly unused if I see this correctly.
I also found this code, where the BASE_URL seems to be hard coded, maybe this can be altered easily.

Thanks for your time and the amazing project. Hope I didn't overlooked anything.

Find here some tries of mine:
I initially thought it might be possible by doing some easy fixes, such as adding a root_path to the fastapis or adding a base path to the svelte.config.js as in this draft pr: https://github.com/tim-roethig-db/open-webui/pull/5

But it looks like this is not enough, since the svelte code contains a lot of hard coded absolute paths in goto, href and src. So I think quite a lot of changes in the svelte files might be necessary as i this draft pr: https://github.com/tim-roethig-db/open-webui/pull/4

Unfortunately both of these tries do not work. The best I achieved was to get the auth and the home screen to be served behind a base path.
