tauri-app-localhost

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
• Dev vs production localhost behavior differences

Trigger phrases include:

• "localhost", "local server", "localhost plugin", "port", "serve frontend"

How to use this skill

1. Install the localhost plugin:

   cargo add tauri-plugin-localhost
   

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

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

3. Configure the frontend URL in tauri.conf.json for production:

   { "build": { "frontendDist": "../dist" } }
   

4. Bind only to 127.0.0.1 to prevent external access to the local server
5. Separate dev-mode access (Vite dev server on port 5173) from production (localhost plugin on a fixed port)
6. 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
