Tauri Dev Invoke Plugin

Invoke Tauri commands from external browsers - identical behavior to WebView.

tauri-plugin-dev-invoke routes HTTP requests through Tauri's real invoke system, so all extractors work (State, AppHandle, Window, etc.).

Installation

Rust

[dependencies]
tauri-plugin-dev-invoke = "0.2"

JavaScript / TypeScript

bun add tauri-plugin-dev-invoke-api

Usage

Rust Setup

Just add the plugin - no extra configuration needed!

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

pub fn run() {
    tauri::Builder::default()
        .plugin(tauri_plugin_dev_invoke::init())
        .invoke_handler(tauri::generate_handler![greet])
        .run(tauri::generate_context!())
        .expect("error");
}

Frontend Setup

import { setupDevInvoke } from "tauri-plugin-dev-invoke-api";

setupDevInvoke();  // Call once at startup

// Then use invoke normally
import { invoke } from "@tauri-apps/api/core";
const response = await invoke("greet", { name: "World" });

Security

• HTTP server only runs in debug mode (#[cfg(debug_assertions)])
• Not included in release builds
• Binds to 127.0.0.1:3030 only (localhost)
