window.__TAURI__ undefined on open local webserver URL

[igorjacauna]

I run, as sidecar, a rust web server on port 7878 that works fine delivering static HTML.

And I have in my tauri.config.json, withGlobalTauri: true:

{
  "$schema": "../node_modules/@tauri-apps/cli/schema.json",
  "build": {
    "beforeBuildCommand": "yarn build",
    "beforeDevCommand": "yarn dev",
    "devPath": "http://localhost:3000",
    "distDir": "../dist",
    "withGlobalTauri": true
  },
  ...
}

But when I open a URL from sidecar rust web server, window.__TAURI__ and all others window.* Tauri APIs are undefined

I open with:

const localServer = new WebviewWindow('local-rust-web-server', {
  url: 'http://localhost:7878/',
});

And if try use window.__TAURI__ on HTML that are delivered by rust web server it is undefined

This is expected behavior. Tauri's apis won't be injected into windows with external-ish urls
