Quasar Capacitor History/Hashmode

[Excel1]

What happened?

I have developed an app with Quasar using Capacitor. My goal is to connect oidc-client.ts to my app. Everything works fine so far, but in production mode the router uses hashmode, although I forced historymode in the configuration file. In the web browser, history mode is used correctly. However, oidc-client.ts expects history mode because it needs the redirect URLs to extract the token, which is not possible in hashmode from Capacitor to Quasar.

What did you expect to happen?

Quasar with Capacitor should using the same router mode. Is it set to history, then history should be used in the app.

Reproduction URL

https://stackblitz.com/edit/quasarframework-dgzdtc?file=src%2Fpages%2FIndexPage.vue,quasar.config.js

How to reproduce?

1. Create or choose a Quasar Project
2. Make sure history-mode is set in quasar.config.js
3. Add capacitor plattform android
4. Build App for production and open in Android Studio
5. Go to Chrome Devtools and inspect app
6. Watch the location url > hashmode "https://localhost/#/"

Does quasar uses different router modes for different deploys? Cause if i force router mode history

  const createHistory = createWebHistory;

it seems to work as it should be

@Excel1: Does quasar uses different router modes for different deploys?

Yes, it does:

quasar/app-vite/lib/quasar-config-file.js

Lines 760 to 765 in a907ebb

	if (this.#ctx.mode.ssr) {
	cfg.build.vueRouterMode = 'history'
	}
	else if (this.#ctx.mode.cordova || this.#ctx.mode.capacitor || this.#ctx.mode.electron || this.#ctx.mode.bex) {
	cfg.build.vueRouterMode = 'hash'
	}

Please see https://capacitorjs.com/docs/config#schema:

    /**
     * Configure the local scheme on iOS.
     *
     * [Can't be set to schemes that the WKWebView already handles, such as http or https](https://developer.apple.com/documentation/webkit/wkwebviewconfiguration/2875766-seturlschemehandler)
     * This can be useful when migrating from
     * [`cordova-plugin-ionic-webview`](https://github.com/ionic-team/cordova-plugin-ionic-webview),
     * where the default scheme on iOS is `ionic`.
     *
     * @since 1.2.0
     * @default capacitor
     */
    iosScheme?: string;

    /**

     *
     * Custom schemes on Android are unable to change the URL path as of Webview 117. Changing this value from anything other than `http` or `https` can result in your

    androidScheme?: string;

The default "URL" is https://localhost on Android, and capacitor://localhost on iOS. Since iOS uses a different URL scheme, it's impossible to use the history mode. That's why it enforces hash mode. You could ask why Quasar enforces that on Android as well, and the answer would be unification and simplicity.

As a side information, Cordova, Electron, and BEX use the file scheme(e.g., file:///...), so we also enforce hash mode in those modes.

If it works, you can modify the const createHistory = ... part to satisfy your use case. But, don't expect it to work under all cases. Here are some resources I've found about the topic that you might want to check:
https://forum.ionicframework.com/t/redirect-back-to-app-after-oauth2-oidc-login/201056
https://stackoverflow.com/questions/71577408/is-it-possible-to-for-an-ionic5-capacitor3-application-to-complete-an-open-i

So, to sum up, this is not an issue. It's the expected behavior and for a good reason.
