npm

npm run tauri add process

yarn

yarn run tauri add process

pnpm

pnpm tauri add process

deno

deno task tauri add process

bun

bun tauri add process

cargo

cargo tauri add process

Manual

1. Run the following command in the src-tauri folder to add the plugin to the project’s dependencies in Cargo.toml:

   cargo add tauri-plugin-process

2. Modify lib.rs to initialize the plugin:

   src-tauri/src/lib.rs

   #[cfg_attr(mobile, tauri::mobile_entry_point)]
   pub fn run() {
       tauri::Builder::default()
           .plugin(tauri_plugin_process::init())
           .run(tauri::generate_context!())
           .expect("error while running tauri application");
   }

3. If you’d like to utilize the plugin in JavaScript then install the npm package as well:

   npm

   npm install @tauri-apps/plugin-process

   yarn

   yarn add @tauri-apps/plugin-process

   pnpm

   pnpm add @tauri-apps/plugin-process

   deno

   deno add npm:@tauri-apps/plugin-process

   bun

   bun add @tauri-apps/plugin-process

Usage

The process plugin is available in both JavaScript and Rust.

JavaScript

import { exit, relaunch } from '@tauri-apps/plugin-process';
// when using `"withGlobalTauri": true`, you may use
// const { exit, relaunch } = window.__TAURI__.process;

// exits the app with the given status code
await exit(0);

// restarts the app
await relaunch();

Rust

Note that app is an instance of AppHandle.

// exits the app with the given status code
app.exit(0);

// restarts the app
app.restart();
