Platform	Level	Notes
windows
linux
macos

ios

Setup

Install the positioner plugin to get started.

Note

If you only intend on moving the window from Rust code, you only need the dependency in src-tauri/Cargo.toml, and can remove the plugin registration from lib.rs if you choose to setup automatically.

Automatic

Use your project’s package manager to add the dependency:

npm

npm run tauri add positioner

yarn

yarn run tauri add positioner

pnpm

pnpm tauri add positioner

deno

deno task tauri add positioner

bun

bun tauri add positioner

cargo

cargo tauri add positioner

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-positioner --target 'cfg(any(target_os = "macos", windows, target_os = "linux"))'

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()
           .setup(|app| {
               #[cfg(desktop)]
               app.handle().plugin(tauri_plugin_positioner::init());
               Ok(())
           })
           .run(tauri::generate_context!())
           .expect("error while running tauri application");
   }

3. Install the JavaScript Guest bindings using your preferred JavaScript package manager:

   npm

   npm install @tauri-apps/plugin-positioner

   yarn

   yarn add @tauri-apps/plugin-positioner

   pnpm

   pnpm add @tauri-apps/plugin-positioner

   deno

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

   bun

   bun add @tauri-apps/plugin-positioner

Additional setup is required to get tray-relative positions to work.

1. Add tray-icon feature to your Cargo.toml file:

   src-tauri/Cargo.toml

   [dependencies]
   tauri-plugin-positioner = { version = "2.0.0", features = ["tray-icon"] }

2. Setup on_tray_event for positioner plugin:

   src-tauri/src/lib.rs

   pub fn run() {
     tauri::Builder::default()
       // This is required to get tray-relative positions to work
       .setup(|app| {
           #[cfg(desktop)]
           {
             app.handle().plugin(tauri_plugin_positioner::init());
               tauri::tray::TrayIconBuilder::new()
                 .on_tray_icon_event(|tray_handle, event| {
                   tauri_plugin_positioner::on_tray_event(tray_handle.app_handle(), &event);
                 })
                 .build(app)?;
           }
         Ok(())
       })
       .run(tauri::generate_context!())
       .expect("error while running tauri application");
   }

Usage

The plugin’s APIs are available through the JavaScript guest bindings:

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

moveWindow(Position.TopRight);

You can import and use the Window trait extension directly through Rust:

use tauri_plugin_positioner::{WindowExt, Position};

let mut win = app.get_webview_window("main").unwrap();
let _ = win.as_ref().window().move_window(Position::TopRight);

Permissions

By default all potentially dangerous plugin commands and scopes are blocked and cannot be accessed. You must modify the permissions in your capabilities configuration to enable these.

See the Capabilities Overview for more information and the step by step guide to use plugin permissions.

{
  "permissions": [
    ...,
    "positioner:default",
  ]
}
