Calling Frontend from Tauri Rust

Tauri provides three mechanisms for Rust to communicate with the frontend: the event system, channels, and JavaScript evaluation.

Event System Overview

The event system enables bi-directional communication between Rust and frontend. Best for small data transfers and multi-consumer patterns. Not designed for low latency or high throughput.

Required Imports

use tauri::{AppHandle, Emitter, Manager, Listener, EventTarget};
use serde::Serialize;

import { listen, once, emit } from '@tauri-apps/api/event';
import { getCurrentWebviewWindow } from '@tauri-apps/api/webviewWindow';
