How to open multiple different local web apps in one tauri-app?

[XX]

I'm making something similar to a superapp. I have a main web app and a bunch of other web apps installed into it. The dist structure is something like this:

dist
  wapp_a
    index.html
    wapp_a.js
    wapp_a.wasm
  wapp_b
    index.html
    wapp_b.js
    wapp_b.wasm
  ...
  index.html
  main.js
  main.wasm

The main application is a manager for other applications (wapp_a, wapp_b, ...) and can launch them. I can create a separate window by calling the command that creates WebviewWindowBuilder, but how do I specify that the new WebviewWindow should open dist/wapp_a/index.html, and not dist/index.html? If I specify a qualifying path in WebviewUrl::App("wapp_a/index.html".into()), it still opens the main index.html, although in the network tab in devtools I see a call to tauri://localhost/wapp_a/index.html.

How can I do this? And if it is possible, how can I isolate the new WebviewWindow so that wapp_a can't access wapp_b assets? If it is not possible, where in the code are there any modifications I could make to make this possible? If this is not possible, where in the Tauri code are there improvements that I could make to make this possible?

hmm, that's supposed to work. A long time ago i did the same too.

that's indeed not supported. can't really point to the best entry point in the code without knowing how to best solve this but this file is where the "server" is https://github.com/tauri-apps/tauri/blob/dev/crates/tauri/src/protocol/tauri.rs

Maybe I'm doing something wrong? But in my example the second app always opens the main one (It's interesting that the links to static images are broken):

Hmm... I logged the URL in on_navigation and on_web_resource_request interceptors but only saw the tauri://localhost/wapp_a/index.html in the output. On the Network tab in devtools I see an additional tauri://localhost/wapp_a/wapp_a.js line, but it's not in the log..

@FabianLars Is there a way to intercept all requests via the tauri:// protocol? (For wapp_a - tauri://localhost/wapp_a/index.html and tauri://localhost/wapp_a/wapp_a.js in my case.)

[FabianLars]

hmm in my app on macos at least on_web_resource_request seems to include all files 🤔
