calling-rust-from-tauri-frontend

To call Rust functions from the frontend in a Tauri v2 app, use the #[tauri::command] attribute to expose backend logic and invoke it via JavaScript using the Tauri invoke API for type-safe IPC.

The best way to handle async Rust commands in Tauri is by defining async functions with #[tauri::command], allowing the frontend to execute non-blocking backend operations that keep the UI responsive.

To pass arguments from JavaScript to Rust commands in Tauri, invoke the command with a JSON object where keys match the Rust function parameter names, ensuring predictable argument marshalling and type-safe IPC.

To register multiple Rust commands in a Tauri v2 application, pass them to the tauri::generate_handler! macro during app setup, creating an organized and scalable pattern for exposing backend logic to the frontend.

Error handling when invoking Rust code from the Tauri frontend involves returning Result types from your #[tauri::command] functions, allowing the frontend to catch and manage backend errors predictably during the invoke call.

Yes, you can use TypeScript to call Tauri backend commands. The invoke API supports JavaScript and TypeScript, allowing you to securely execute Rust backend logic with type-safe argument naming and return types.
