Does renderer.bundle.js hard-code port 13305 into the App? #2325

Finally have lemonade-server up on Fedora 44 with two AMD R9700's, and serving the local network over 0.0.0.0 on port 8080 (I recently changed to :8080 because Firefox allows sidebar > local there).

Accessing http://server.ip:8080 on local desktops takes me to the local server's App.

Accessing the same on my iPhone/iPad immediately takes me to Apple's App Store...

scratches head

I hooked the iPhone up to a local Mac, and Safari Web Inspector showed me:

<!doctype html><html lang="en"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-width,initial-scale=1"><meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'; media-src 'self' blob: data:; img-src 'self' data: blob: https:; connect-src 'self' http: https: ws: wss: ipc: tauri:; frame-src 'self' https://lemonade-server.ai file:;"><title>Lemonade App</title><link rel="icon" type="image/x-icon" href="favicon.ico"><script defer="defer" src="renderer.bundle.js"></script>

    maximizeWindow: () => {},
    closeWindow: () => {},
    openExternal: (url) => window.open(url, '_blank'),
    onMaximizeChange: () => {},
    updateMinWidth: () => {},
    zoomIn: () => document.body.style.zoom = (parseFloat(document.body.style.zoom || '1') + 0.1).toString(),

    getSettings: async () => {
        const saved = localStorage.getItem('lemonade-settings');
        if (saved) return JSON.parse(saved);
        // Return defaults matching DEFAULT_LAYOUT_SETTINGS from appSettings.ts
        return {
            layout: {
                isChatVisible: true,
                isModelManagerVisible: true,
                isCenterPanelVisible: true,
                isLogsVisible: false,
                modelManagerWidth: 280,
                chatWidth: 350,
                logsHeight: 200
            },
            theme: 'dark',
            apiUrl: window.location.origin,
            apiKey: { value: '' }
        };
    },
    saveSettings: async (settings) => {
        localStorage.setItem('lemonade-settings', JSON.stringify(settings));
        return settings;
    },
    onSettingsUpdated: () => {},
    getServerPort: () => parseInt(window.location.port) || 13305,
    onServerPortUpdated: () => {},
    getServerAPIKey: async () => {
        const settings = await window.api.getSettings();
        return settings.apiKey?.value || '';
    },
    restartApp: () => window.location.reload()
};
</script>
</head><body><div id="root"></div></body></html>

I noticed:

<script defer="defer" src="renderer.bundle.js"></script>

and:

    getServerPort: () => parseInt(window.location.port) || 13305,
    onServerPortUpdated: () => {},

So, I went digging, and couldn't find renderer.bundle.js in the source here on GH. Further digging found:

splifingate@Fedora:~$ /opt/share/lemonade-server/resources/web-app/renderer.bundle.js

with these inside:

("input",{type:"text",value:e.baseURL.value,placeholder:"http://localhost:13305/",onChange:e=>t("baseURL",e.target.value)

t.serverConfig=new class{constructor(){this.port=13305,this.explicitBaseUrl=null,this.apiKey=null,this.portListeners=new

Every time I go directly to http://server.ip:8080, Safari opens the App Store to the Lemonade App by Geramy Loveless . . . but no love lost! :)

So, I changed the default port back to :13305, and I received the same result as above. M4 IPP gets the same results (Geramy's App works well there FWIW).

Apple is always going to be Apple, but could it be that the hard-coded :13305 port
in renderer.bundle.js is confusing my transaction?

I was expecting a direct line to the Lemonade App on the server using my iPhone/iPad just like the desktops...

Oh, and many thanks for the tasty Lemonade :)

I think the App Store jump is not caused by the 13305 default.

In current source, the redirect is in src/app/src/renderer/index.tsx, before the React app is mounted:

Android -> Play Store
iPad/iPhone/iPod -> https://apps.apple.com/ca/app/lemonade-mobile/id6757372210
otherwise render <App />

So on iPhone/iPad the bundle intentionally leaves the local web UI immediately. The 13305 values you found are defaults/fallbacks: web mode injects window.api.isWebApp = true; serverConfig.ts then uses window.location.origin as the base URL, and the C++ mock returns parseInt(window.location.port) || 13305 only as fallback.

For a local LAN web UI on mobile, the redirect in index.tsx would need to be r…

For a local LAN web UI on mobile, the redirect in index.tsx would need to be removed or gated, for example not running it when the app is served by the local web server. As a quick confirmation, try forcing desktop site in Safari or temporarily patching that mobile redirect out and rebuilding the web app; the port can stay 8080 if the page is served from that origin.

I really appreciate the detailed explanation! Glad to know I haven't fully lost my mind smile

I see the redirects in the .tsx, and will leave 'em be (haven't tried forcing desktop in Safari).

Geramy's app on iPad is a little raw, but pretty good.

Thank's for the verification!
