GitHub npm crates.io

API Reference

Save window positions and sizes and restore them when the app is reopened.

Supported Platforms

• Windows
• Linux
• macOS

Setup

This plugin requires a Rust version of at least 1.75

Install the window-state plugin to get started.

Automatic

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

npm

npm run tauri add window-state

yarn

yarn run tauri add window-state

pnpm

pnpm tauri add window-state

bun

bun tauri add window-state

cargo

cargo tauri add window-state

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-window-state --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_window_state::Builder::default().build());
               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-window-state

   yarn

   yarn add @tauri-apps/plugin-window-state

   pnpm

   pnpm add @tauri-apps/plugin-window-state

   bun

   bun add @tauri-apps/plugin-window-state

Usage

After adding the all windows will remember their state when the app is being closed and will restore to their previous state on the next launch.

You can also access the window-state plugin in both JavaScript and Rust.

JavaScript

You can use saveWindowState to manually save the window state:

import { saveWindowState, StateFlags } from '@tauri-apps/plugin-window-state';
// when using `"withGlobalTauri": true`, you may use
// const { saveWindowState, StateFlags } = window.__TAURI_PLUGIN_WINDOW_STATE__;

saveWindowState(StateFlags.ALL);

Similarly you can manually restore a window’s state from disk:

import {
  restoreStateCurrent,
  StateFlags,
} from '@tauri-apps/plugin-window-state';
// when using `"withGlobalTauri": true`, you may use
// const { restoreStateCurrent, StateFlags } = window.__TAURI_PLUGIN_WINDOW_STATE__;

restoreStateCurrent(StateFlags.ALL);

Rust

You can use the save_window_state() method exposed by the AppHandleExt trait:

use tauri_plugin_window_state::{AppHandleExt, StateFlags};

// `tauri::AppHandle` now has the following additional method
app.save_window_state(StateFlags::all()); // will save the state of all open windows to disk

Similarly you can manually restore a window’s state from disk using the restore_state() method exposed by the WindowExt trait:

use tauri_plugin_window_state::{WindowExt, StateFlags};

// all `Window` types now have the following additional method
window.restore_state(StateFlags::all()); // will restore the window's state from disk

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.

src-tauri/capabilities/main.json

{
  "permissions": [
    ...,
    "window-state:allow-restore-state",
    "window-state:allow-save-window-state",
  ]
}
