Hi, Can you please add the browser's DevTools logs or a screenshot?

Thank you for the quick reply.
Index.html loads but is blank:
If I right-click and inspect the JS console, I see:
And here is index.html:
(NOTE: I have to put the webui.js script below the SvelteKit starter script; otherwise, it gets into an infinite loop, crashing, Kit restarting, repeat.)

WAIT -- I think I found the problem -- not a webui thing, so don't waste any more of your time.
I switched to Windows dev (from WSL Ubuntu) for Zig, and my Windows CouchDb settings are I think the problem. I'm going down that route and will report back (and probably close this).

Yes, that's what I was about to write, your server at 5984 should allow Access-Control-Allow-Origin from *.

Yes, I had not copied all settings correctly, so the CORS issue is solved.
However, the infinite loop (crash / reload) described above is still happening, regardless of where I place the webui.js script (See "NOTE", above).
My app starts to load (screenshot):
...but then it seems to be looking for index.html again, cannot find it, crashes, and sveltekit reloads.
Here's the console (pink is crashing, all the white logs are successful API calls; this repeats in a loop):

If you want to use a custom web server with WebUI, you can then look at this C example on how to do that.
The example is using a Python web server, and using WebUI to show a window, and track the click events using webui.js.

Thanks, but no I don't need to write a server, it's just a SvelteKit SPA, with only client-side code. (SvelteKit can do server side, and is probably used mostly for that, but it also does SPAs by turning off all server-side stuff.)
The SPA makes many fetch calls to APIs that are separate apps.
I have a suspicion about what's happening, and that the problem is due to SvelteKit's client-side router or other code that SvelteKit generates. (SvelteKit does a ton behind the scenes, which is why it's so easy to write apps. But this ton of stuff is all compiled and mostly impenetrable by me.)
Anyway, what I think is happening:
- Something is happening to cause an error, during the initial load
- SvelteKit handles errors by reloading or re-routing
- WebUI is also responding to this re-routing, and tries to load index.html again...
- which triggers the error; goto (1)
I'll figure it out and, if it's of interest to the WebUI community I'll post back.
Closing this for now.

Yes, I'm interested in learning more about this issue. We can improve WebUI or add a new option to make it more flexible to handle this kind of situation. When you have free time. Thank you.

It seems to be a fundamental conflict with how SvelteKit works. I created a test project that has the same problem. The project is linked to in the new issue I opened: #392
