Orchestration & Integration

Connects and orchestrates with relevant domain skills like brainstorming, zero-to-prod-orchestrator, and project-context-mapper to ensure cohesive execution.

Description

This skill provides best practice guidance for building cross-platform desktop and mobile applications using Tauri (specifically Tauri v2). It covers frontend integration with the Rust backend, Inter-Process Communication (IPC), state management, and security.

Instructions & Best Practices

1. Architecture & IPC (Inter-Process Communication)

• Use tauri::command to define Rust functions callable from the frontend.
• Invoke Rust functions from the frontend using @tauri-apps/api/core (invoke).
• Utilize Tauri's event system (emit from Rust, listen on frontend) for real-time or async updates.
• Keep heavy processing and filesystem access in Rust (backend), while the frontend focuses purely on UI.

2. State Management (Rust Backend)

• Use tauri::State to store and manage global state in the Rust backend.
• Use std::sync::Mutex or tokio::sync::Mutex (if async) for mutable state.
• Initialize managed state during application setup: tauri::Builder::default().manage(MyState::default()).

3. Security & Capabilities

• Enforce strict context isolation.
• In Tauri v2, use the Capabilities system to restrict API access per window or plugin.
• Never expose dangerous filesystem, shell, or network APIs globally. Only grant allowlist access to specific, required paths or commands.

4. Performance & Concurrency

• Use async fn for tauri::command when handling heavy I/O to avoid blocking the main thread.
• Use serde (Serialize, Deserialize) efficiently for data structures sent between Rust and the frontend.

5. Plugin Management (Tauri v2)

• Use official Tauri plugins (e.g., tauri-plugin-fs, tauri-plugin-store, tauri-plugin-dialog) instead of writing custom I/O modules when available.
• Initialize plugins in main.rs or lib.rs: app.plugin(tauri_plugin_dialog::init()).
