When to use this skill

ALWAYS use this skill when the user mentions:

Serving frontend via localhost in a Tauri app
Local server exposure and port configuration

How to use this skill

Install the localhost plugin:
```
cargo add tauri-plugin-localhost
```

Register the plugin with a specific port in your Tauri builder:

tauri::Builder::default()
    .plugin(tauri_plugin_localhost::Builder::new(3030).build())

Configure the frontend URL in tauri.conf.json for production:
```
{ "build": { "frontendDist": "../dist" } }
```
Bind only to 127.0.0.1 to prevent external access to the local server
Separate dev-mode access (Vite dev server on port 5173) from production (localhost plugin on a fixed port)
Audit access patterns to ensure minimal exposure in production builds

Outputs

Localhost plugin configuration with fixed port
Dev vs production server separation
Security checklist for minimal exposure
