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

Cargo

cargo tauri add window-state

Manual

1. Install the Core plugin by adding the following to your Cargo.toml file:

   src-tauri/Cargo.toml

   [dependencies]
   tauri-plugin-window-state = "2.0.0-beta"
   # alternatively with Git:
   tauri-plugin-window-state = { git = "https://github.com/tauri-apps/plugins-workspace", branch = "v2" }

2. Modify lib.rs to initialize the plugin:

   src-tauri/src/lib.rs

   fn run() {
       tauri::Builder::default()
           .plugin(tauri_plugin_window_state::Builder::default().build())
           .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

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';

saveWindowState(StateFlags.ALL);

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

import {
  restoreStateCurrent,
  StateFlags,
} from '@tauri-apps/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
