Commands (Frontend → Rust)

Define commands in Rust with #[tauri::command]:

// src-tauri/src/lib.rs
#[tauri::command]
fn greet(name: String) -> String {
    format!("Hello, {}!", name)
}

#[tauri::command]
async fn read_file(path: String) -> Result<String, String> {
    std::fs::read_to_string(&path).map_err(|e| e.to_string())
}

pub fn run() {
    tauri::Builder::default()
        .invoke_handler(tauri::generate_handler![greet, read_file])
        .run(tauri::generate_context!())
        .expect("error running app");
}

Call from frontend (direct):

import { invoke } from '@tauri-apps/api/core';

const greeting = await invoke<string>('greet', { name: 'World' });
const content = await invoke<string>('read_file', { path: '/tmp/test.txt' });
