-# The config expects the following environment variables to be set:
-#  - "GN_CONFIG" Build type. One of {'testing', 'release'}.
-#  - "GN_EXTRA_ARGS" Additional gn arguments for a build config,
-#      e.g. 'target_cpu="x86"' to build for a 32bit platform.
-#      https://gn.googlesource.com/gn/+/main/docs/reference.md#var_target_cpu
-#      Don't forget to set up "NPM_CONFIG_ARCH" and "TARGET_ARCH" accordingly
-#      if you pass a custom value for 'target_cpu'.
-#  - "ELECTRON_RELEASE" Set it to '1' upload binaries on success.
-#  - "NPM_CONFIG_ARCH" E.g. 'x86'. Is used to build native Node.js modules.
-#      Must match 'target_cpu' passed to "GN_EXTRA_ARGS" and "TARGET_ARCH" value.
-#  - "TARGET_ARCH" Choose from {'ia32', 'x64', 'arm', 'arm64'}.
-#      Is used in some publishing scripts, but does NOT affect the Electron binary.
-#      Must match 'target_cpu' passed to "GN_EXTRA_ARGS" and "NPM_CONFIG_ARCH" value.
-#  - "UPLOAD_TO_STORAGE" Set it to '1' upload a release to the Azure bucket.
-#      Otherwise the release will be uploaded to the GitHub Releases.
-#      (The value is only checked if "ELECTRON_RELEASE" is defined.)

+# Custom Title Bar
+
+## Basic tutorial
+
+Application windows have a default [chrome][] applied by the OS. Not to be confused
+with the Google Chrome browser, window _chrome_ refers to the parts of the window (e.g.
+title bar, toolbars, controls) that are not a part of the main web content. While the
+default title bar provided by the OS chrome is sufficent for simple use cases, many
+applications opt to remove it. Implementing a custom title bar can help your application
+feel more modern and consistent across platforms.
+
+You can follow along with this tutorial by opening Fiddle with the following starter code.
+
+```fiddle docs/fiddles/features/window-customization/custom-title-bar/starter-code
+
+```
+
+### Remove the default title bar
+
+Let’s start by configuring a window with native window controls and a hidden title bar.
+To remove the default title bar, set the [`BaseWindowContructorOptions`][] `titleBarStyle`
+param in the `BrowserWindow` constructor to `'hidden'`.
+
+```fiddle docs/fiddles/features/window-customization/custom-title-bar/remove-title-bar
+
+```
+
+### Add native window controls _Windows_ _Linux_
+
+On macOS, setting `titleBarStyle: 'hidden'` removes the title bar while keeping the window’s
+traffic light controls available in the upper left hand corner. However on Windows and Linux,
+you’ll need to add window controls back into your `BrowserWindow` by setting the
+[`BaseWindowContructorOptions`][] `titleBarOverlay` param in the `BrowserWindow` constructor.
+
+```fiddle docs/fiddles/features/window-customization/custom-title-bar/native-window-controls
+
+```
+
+Setting `titleBarOverlay: true` is the simplest way to expose window controls back into
+your `BrowserWindow`. If you’re interested in customizing the window controls further,
+check out the sections [Custom traffic lights][] and [Custom window controls][] that cover
+this in more detail.
+
+### Create a custom title bar
+
+Now, let’s implement a simple custom title bar in the `webContents` of our `BrowserWindow`.
+There’s nothing fancy here, just HTML and CSS!
+
+```fiddle docs/fiddles/features/window-customization/custom-title-bar/custom-title-bar
+
+```
+
+Currently our application window can’t be moved. Since we’ve removed the default title bar,
+the application needs to tell Electron which regions are draggable. We’ll do this by adding
+the CSS style `app-region: drag` to the custom title bar. Now we can drag the custom title
+bar to reposition our app window!
+
+```fiddle docs/fiddles/features/window-customization/custom-title-bar/custom-drag-region
+
+```
+
+For more information around how to manage drag regions defined by your electron application,
+see the [Custom draggable regions][] section below.
+
+Congratulations, you've just implemented a basic custom title bar!
+
+## Advanced window customization
+
+### Custom traffic lights _macOS_
+
+#### Customize the look of your traffic lights _macOS_
+
+The `customButtonsOnHover` title bar style will hide the traffic lights until you hover
+over them. This is useful if you want to create custom traffic lights in your HTML but still
+use the native UI to control the window.
+
+```js
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'customButtonsOnHover' })
+```
+
+#### Customize the traffic light position _macOS_
+
+To modify the position of the traffic light window controls, there are two configuration
+options available.
+
+Applying `hiddenInset` title bar style will shift the vertical inset of the traffic lights
+by a fixed amount.
+
+```js title='main.js'
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'hiddenInset' })
+```
+
+If you need more granular control over the positioning of the traffic lights, you can pass
+a set of coordinates to the `trafficLightPosition` option in the `BrowserWindow`
+constructor.
+
+```js title='main.js'
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({
+  titleBarStyle: 'hidden',
+  trafficLightPosition: { x: 10, y: 10 }
+})
+```
+
+#### Show and hide the traffic lights programmatically _macOS_
+
+You can also show and hide the traffic lights programmatically from the main process.
+The `win.setWindowButtonVisibility` forces traffic lights to be show or hidden depending
+on the value of its boolean parameter.
+
+```js title='main.js'
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow()
+// hides the traffic lights
+win.setWindowButtonVisibility(false)
+```
+
+:::note
+Given the number of APIs available, there are many ways of achieving this. For instance,
+combining `frame: false` with `win.setWindowButtonVisibility(true)` will yield the same
+layout outcome as setting `titleBarStyle: 'hidden'`.
+:::
+
+#### Custom window controls
+
+The [Window Controls Overlay API][] is a web standard that gives web apps the ability to
+customize their title bar region when installed on desktop. Electron exposes this API
+through the `titleBarOverlay` option in the `BrowserWindow` constructor. When `titleBarOverlay`
+is enabled, the window controls become exposed in their default position, and DOM elements
+cannot use the area underneath this region.
+
+:::note
+`titleBarOverlay` requires the `titleBarStyle` param in the `BrowserWindow` constructor
+to have a value other than `default`.
+:::
+
+The custom title bar tutorial covers a [basic example][Add native window controls] of exposing
+window controls by setting `titleBarOverlay: true`. The height, color (_Windows_ _Linux_), and
+symbol colors (_Windows_) of the window controls can be customized further by setting
+`titleBarOverlay` to an object.
+
+The value passed to the `height` property must be an integer. The `color` and `symbolColor`
+properties accept `rgba()`, `hsla()`, and `#RRGGBBAA` color formats and support transparency.
+If a color option is not specified, the color will default to its system color for the window
+control buttons. Similarly, if the height option is not specified, the window controls will
+default to the standard system height:
+
+```js title='main.js'
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({
+  titleBarStyle: 'hidden',
+  titleBarOverlay: {
+    color: '#2f3241',
+    symbolColor: '#74b1be',
+    height: 60
+  }
+})
+```
+
+:::note
+Once your title bar overlay is enabled from the main process, you can access the overlay's
+color and dimension values from a renderer using a set of readonly
+[JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars].

+# Custom Window Interactions
+
+## Custom draggable regions
+
+By default, windows are dragged using the title bar provided by the OS chrome. Apps
+that remove the default title bar need to use the `app-region` CSS property to define
+specific areas that can be used to drag the window. Setting `app-region: drag` marks
+a rectagular area as draggable.
+
+It is important to note that draggable areas ignore all pointer events. For example,
+a button element that overlaps a draggable region will not emit mouse clicks or mouse
+enter/exit events within that overlapping area. Setting `app-region: no-drag` reenables
+pointer events by excluding a rectagular area from a draggable region.
+
+To make the whole window draggable, you can add `app-region: drag` as
+`body`'s style:
+
+```css title='styles.css'
+body {
+  app-region: drag;
+}
+```
+
+And note that if you have made the whole window draggable, you must also mark
+buttons as non-draggable, otherwise it would be impossible for users to click on
+them:
+
+```css title='styles.css'
+button {
+  app-region: no-drag;
+}
+```
+
+If you're only setting a custom title bar as draggable, you also need to make all
+buttons in title bar non-draggable.
+
+### Tip: disable text selection
+
+When creating a draggable region, the dragging behavior may conflict with text selection.
+For example, when you drag the title bar, you may accidentally select its text contents.
+To prevent this, you need to disable text selection within a draggable area like this:
+
+```css
+.titlebar {
+  user-select: none;
+  app-region: drag;
+}
+```
+
+### Tip: disable context menus
+
+On some platforms, the draggable area will be treated as a non-client frame, so
+when you right click on it, a system menu will pop up. To make the context menu
+behave correctly on all platforms, you should never use a custom context menu on
+draggable areas.
+
+## Click-through windows
+
+To create a click-through window, i.e. making the window ignore all mouse
+events, you can call the [win.setIgnoreMouseEvents(ignore)][ignore-mouse-events]
+API:
+
+```js title='main.js'
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow()
+win.setIgnoreMouseEvents(true)
+```
+
+### Forward mouse events _macOS_ _Windows_
+
+Ignoring mouse messages makes the web contents oblivious to mouse movement,
+meaning that mouse movement events will not be emitted. On Windows and macOS, an
+optional parameter can be used to forward mouse move messages to the web page,
+allowing events such as `mouseleave` to be emitted:
+
+```js title='main.js'
+const { BrowserWindow, ipcMain } = require('electron')
+const path = require('node:path')
+
+const win = new BrowserWindow({
+  webPreferences: {
+    preload: path.join(__dirname, 'preload.js')
+  }
+})
+
+ipcMain.on('set-ignore-mouse-events', (event, ignore, options) => {
+  const win = BrowserWindow.fromWebContents(event.sender)
+  win.setIgnoreMouseEvents(ignore, options)
+})
+```
+
+```js title='preload.js'
+window.addEventListener('DOMContentLoaded', () => {
+  const el = document.getElementById('clickThroughElement')
+  el.addEventListener('mouseenter', () => {
+    ipcRenderer.send('set-ignore-mouse-events', true, { forward: true })
+  })
+  el.addEventListener('mouseleave', () => {
+    ipcRenderer.send('set-ignore-mouse-events', false)
+  })
+})
+```
+
+This makes the web page click-through when over the `#clickThroughElement` element,
+and returns to normal outside it.

+## Frameless windows
+
+![Frameless Window](../images/frameless-window.png)
+
+A frameless window removes all [chrome][] applied by the OS, including window controls.
+
+To create a frameless window, set the [`BaseWindowContructorOptions`][] `frame` param in the `BrowserWindow` constructor to `false`.
+
+```fiddle docs/fiddles/features/window-customization/custom-window-styles/frameless-windows
+
+```
+
+## Transparent windows
+
+![Transparent Window](../images/transparent-window.png)
+![Transparent Window in macOS Mission Control](../images/transparent-window-mission-control.png)
+
+To create a fully transparent window, set the [`BaseWindowContructorOptions`][] `transparent` param in the `BrowserWindow` constructor to `true`.
+
+The following fiddle takes advantage of a tranparent window and CSS styling to create
+the illusion of a circular window.
+
+```fiddle docs/fiddles/features/window-customization/custom-window-styles/transparent-windows
+
+```
+
+### Limitations
+
+* You cannot click through the transparent area. See
+  [#1335](https://github.com/electron/electron/issues/1335) for details.
+* Transparent windows are not resizable. Setting `resizable` to `true` may make
+  a transparent window stop working on some platforms.
+* The CSS [`blur()`][] filter only applies to the window's web contents, so there is
+  no way to apply blur effect to the content below the window (i.e. other applications
+  open on the user's system).
+* The window will not be transparent when DevTools is opened.
+* On _Windows_:
+  * Transparent windows will not work when DWM is disabled.
+  * Transparent windows can not be maximized using the Windows system menu or by double
+  clicking the title bar. The reasoning behind this can be seen on
+  PR [#28207](https://github.com/electron/electron/pull/28207).
+* On _macOS_:
+  * The native window shadow will not be shown on a transparent window.

+Using separate snapshots for renderer processes and the main process can improve security, especially to make sure that the renderer doesn't use a snapshot with `nodeIntegration` enabled. See [#35170](https://github.com/electron/electron/issues/35170) for details.

-# Quick Start
-
-This guide will step you through the process of creating a barebones Hello World app in
-Electron, similar to [`electron/electron-quick-start`][quick-start].
-
-By the end of this tutorial, your app will open a browser window that displays a web page
-with information about which Chromium, Node.js, and Electron versions are running.
-
-[quick-start]: https://github.com/electron/electron-quick-start
-
-## Prerequisites
-
-To use Electron, you need to install [Node.js][node-download]. We recommend that you
-use the latest `LTS` version available.
-
-> Please install Node.js using pre-built installers for your platform.
-> You may encounter incompatibility issues with different development tools otherwise.
-
-To check that Node.js was installed correctly, type the following commands in your
-terminal client:
-
-```sh
-node -v
-npm -v
-```
-
-The commands should print the versions of Node.js and npm accordingly.
-
-**Note:** Since Electron embeds Node.js into its binary, the version of Node.js running
-your code is unrelated to the version running on your system.
-
-[node-download]: https://nodejs.org/en/download/
-
-## Create your application
-
-### Scaffold the project
-
-Electron apps follow the same general structure as other Node.js projects.
-Start by creating a folder and initializing an npm package.
-
-```sh npm2yarn
-mkdir my-electron-app && cd my-electron-app
-npm init
-```
-
-The interactive `init` command will prompt you to set some fields in your config.
-There are a few rules to follow for the purposes of this tutorial:
-
-* `entry point` should be `main.js`.
-* `author` and `description` can be any value, but are necessary for
-[app packaging](#package-and-distribute-your-application).
-
-Your `package.json` file should look something like this:
-
-```json
-{
-  "name": "my-electron-app",
-  "version": "1.0.0",
-  "description": "Hello World!",
-  "main": "main.js",
-  "author": "Jane Doe",
-  "license": "MIT"
-}
-```
-
-Then, install the `electron` package into your app's `devDependencies`.
-
-```sh npm2yarn
-npm install --save-dev electron
-```
-
-> Note: If you're encountering any issues with installing Electron, please
-> refer to the [Advanced Installation][advanced-installation] guide.
-
-Finally, you want to be able to execute Electron. In the [`scripts`][package-scripts]
-field of your `package.json` config, add a `start` command like so:
-
-```json
-{
-  "scripts": {
-    "start": "electron ."
-  }
-}
-```
-
-This `start` command will let you open your app in development mode.
-
-```sh npm2yarn
-npm start
-```
-
-> Note: This script tells Electron to run on your project's root folder. At this stage,
-> your app will immediately throw an error telling you that it cannot find an app to run.
-
-[advanced-installation]: ./installation.md
-[package-scripts]: https://docs.npmjs.com/cli/v7/using-npm/scripts
-
-### Run the main process
-
-The entry point of any Electron application is its `main` script. This script controls the
-**main process**, which runs in a full Node.js environment and is responsible for
-controlling your app's lifecycle, displaying native interfaces, performing privileged
-operations, and managing renderer processes (more on that later).
-
-During execution, Electron will look for this script in the [`main`][package-json-main]
-field of the app's `package.json` config, which you should have configured during the
-[app scaffolding](#scaffold-the-project) step.
-
-To initialize the `main` script, create an empty file named `main.js` in the root folder
-of your project.
-
-> Note: If you run the `start` script again at this point, your app will no longer throw
-> any errors! However, it won't do anything yet because we haven't added any code into
-> `main.js`.
-
-[package-json-main]: https://docs.npmjs.com/cli/v7/configuring-npm/package-json#main
-
-### Create a web page
-
-Before we can create a window for our application, we need to create the content that
-will be loaded into it. In Electron, each window displays web contents that can be loaded
-from either a local HTML file or a remote URL.
-
-For this tutorial, you will be doing the former. Create an `index.html` file in the root
-folder of your project:
-
-```html
-<!DOCTYPE html>
-<html lang="en">
-  <head>
-    <meta charset="UTF-8">
-    <!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
-    <meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
-    <title>Hello World!</title>
-  </head>
-  <body>
-    <h1>Hello World!</h1>
-    We are using Node.js <span id="node-version"></span>,
-    Chromium <span id="chrome-version"></span>,
-    and Electron <span id="electron-version"></span>.
-  </body>
-</html>
-```
-
-> Note: Looking at this HTML document, you can observe that the version numbers are
-> missing from the body text. We'll manually insert them later using JavaScript.
-
-### Opening your web page in a browser window
-
-Now that you have a web page, load it into an application window. To do so, you'll
-need two Electron modules:
-
-* The [`app`][app] module, which controls your application's event lifecycle.
-* The [`BrowserWindow`][browser-window] module, which creates and manages application
-  windows.
-
-Because the main process runs Node.js, you can import these as [CommonJS][commonjs]
-modules at the top of your `main.js` file:
-
-```js
-const { app, BrowserWindow } = require('electron')
-```
-
-Then, add a `createWindow()` function that loads `index.html` into a new `BrowserWindow`
-instance.
-
-```js
-const createWindow = () => {
-  const win = new BrowserWindow({
-    width: 800,
-    height: 600
-  })
-
-  win.loadFile('index.html')
-}
-```
-
-Next, call this `createWindow()` function to open your window.
-
-In Electron, browser windows can only be created after the `app` module's
-[`ready`][app-ready] event is fired. You can wait for this event by using the
-[`app.whenReady()`][app-when-ready] API. Call `createWindow()` after `whenReady()`
-resolves its Promise.
-
-```js @ts-type={createWindow:()=>void}
-app.whenReady().then(() => {
-  createWindow()
-})
-```
-
-> Note: At this point, your Electron application should successfully
-> open a window that displays your web page!
-
-[app]: ../api/app.md
-[browser-window]: ../api/browser-window.md
-[commonjs]: https://nodejs.org/docs/latest/api/modules.html#modules_modules_commonjs_modules
-[app-ready]: ../api/app.md#event-ready
-[app-when-ready]: ../api/app.md#appwhenready
-
-### Manage your window's lifecycle
-
-Although you can now open a browser window, you'll need some additional boilerplate code
-to make it feel more native to each platform. Application windows behave differently on
-each OS, and Electron puts the responsibility on developers to implement these
-conventions in their app.
-
-In general, you can use the `process` global's [`platform`][node-platform] attribute
-to run code specifically for certain operating systems.
-
-#### Quit the app when all windows are closed (Windows & Linux)
-
-On Windows and Linux, exiting all windows generally quits an application entirely.
-
-To implement this, listen for the `app` module's [`'window-all-closed'`][window-all-closed]
-event, and call [`app.quit()`][app-quit] if the user is not on macOS (`darwin`).
-
-```js
-app.on('window-all-closed', () => {
-  if (process.platform !== 'darwin') app.quit()
-})
-```
-
-[node-platform]: https://nodejs.org/api/process.html#process_process_platform
-[window-all-closed]: ../api/app.md#event-window-all-closed
-[app-quit]: ../api/app.md#appquit
-
-#### Open a window if none are open (macOS)
-
-Whereas Linux and Windows apps quit when they have no windows open, macOS apps generally
-continue running even without any windows open, and activating the app when no windows
-are available should open a new one.
-
-To implement this feature, listen for the `app` module's [`activate`][activate]
-event, and call your existing `createWindow()` method if no browser windows are open.
-
-Because windows cannot be created before the `ready` event, you should only listen for
-`activate` events after your app is initialized. Do this by attaching your event listener
-from within your existing `whenReady()` callback.
-
-[activate]: ../api/app.md#event-activate-macos
-
-```js @ts-type={createWindow:()=>void}
-app.whenReady().then(() => {
-  createWindow()
-
-  app.on('activate', () => {
-    if (BrowserWindow.getAllWindows().length === 0) createWindow()
-  })
-})
-```
-
-> Note: At this point, your window controls should be fully functional!
-
-### Access Node.js from the renderer with a preload script
-
-Now, the last thing to do is print out the version numbers for Electron and its
-dependencies onto your web page.
-
-Accessing this information is trivial to do in the main process through Node's
-global `process` object. However, you can't just edit the DOM from the main
-process because it has no access to the renderer's `document` context.
-They're in entirely different processes!
-
-> Note: If you need a more in-depth look at Electron processes, see the
-> [Process Model][] document.
-
-This is where attaching a **preload** script to your renderer comes in handy.
-A preload script runs before the renderer process is loaded, and has access to both
-renderer globals (e.g. `window` and `document`) and a Node.js environment.
-
-Create a new script named `preload.js` as such:
-
-```js
-window.addEventListener('DOMContentLoaded', () => {
-  const replaceText = (selector, text) => {
-    const element = document.getElementById(selector)
-    if (element) element.innerText = text
-  }
-
-  for (const dependency of ['chrome', 'node', 'electron']) {
-    replaceText(`${dependency}-version`, process.versions[dependency])
-  }
-})
-```
-
-The above code accesses the Node.js `process.versions` object and runs a basic `replaceText`
-helper function to insert the version numbers into the HTML document.
-
-To attach this script to your renderer process, pass in the path to your preload script
-to the `webPreferences.preload` option in your existing `BrowserWindow` constructor.
-
-```js
-const { app, BrowserWindow } = require('electron')
-// include the Node.js 'path' module at the top of your file
-const path = require('node:path')
-
-// modify your existing createWindow() function
-const createWindow = () => {
-  const win = new BrowserWindow({
-    width: 800,
-    height: 600,
-    webPreferences: {
-      preload: path.join(__dirname, 'preload.js')
-    }
-  })
-
-  win.loadFile('index.html')
-}
-// ...
-```
-
-There are two Node.js concepts that are used here:
-
-* The [`__dirname`][dirname] string points to the path of the currently executing script
-  (in this case, your project's root folder).
-* The [`path.join`][path-join] API joins multiple path segments together, creating a
-  combined path string that works across all platforms.
-
-We use a path relative to the currently executing JavaScript file so that your relative
-path will work in both development and packaged mode.
-
-[Process Model]: ./process-model.md
-[dirname]: https://nodejs.org/api/modules.html#modules_dirname
-[path-join]: https://nodejs.org/api/path.html#path_path_join_paths
-
-### Bonus: Add functionality to your web contents
-
-At this point, you might be wondering how to add more functionality to your application.
-
-For any interactions with your web contents, you want to add scripts to your
-renderer process. Because the renderer runs in a normal web environment, you can add a
-`<script>` tag right before your `index.html` file's closing `</body>` tag to include
-any arbitrary scripts you want:
-
-```html
-<script src="./renderer.js"></script>
-```
-
-The code contained in `renderer.js` can then use the same JavaScript APIs and tooling
-you use for typical front-end development, such as using [`webpack`][webpack] to bundle
-and minify your code or [React][react] to manage your user interfaces.
-
-[webpack]: https://webpack.js.org
-[react]: https://reactjs.org
-
-### Recap
-
-After following the above steps, you should have a fully functional
-Electron application that looks like this:

-To summarize all the steps we've done:
-
-* We bootstrapped a Node.js application and added Electron as a dependency.
-* We created a `main.js` script that runs our main process, which controls our app
-  and runs in a Node.js environment. In this script, we used Electron's `app` and
-  `BrowserWindow` modules to create a browser window that displays web content
-  in a separate process (the renderer).
-* In order to access certain Node.js functionality in the renderer, we attached
-  a preload script to our `BrowserWindow` constructor.
-
-## Package and distribute your application
-
-The fastest way to distribute your newly created app is using
-[Electron Forge](https://www.electronforge.io).
-
-:::info
-
-To build an RPM package for Linux, you will need to [install its required system dependencies](https://www.electronforge.io/config/makers/rpm).
-
-:::
-
-1. Add a description to your `package.json` file, otherwise rpmbuild will fail. Blank description are not valid.
-2. Add Electron Forge as a development dependency of your app, and use its `import` command to set up
-Forge's scaffolding:
-
-   ```sh npm2yarn
-   npm install --save-dev @electron-forge/cli
-   npx electron-forge import
-
-   ✔ Checking your system
-   ✔ Initializing Git Repository
-   ✔ Writing modified package.json file
-   ✔ Installing dependencies
-   ✔ Writing modified package.json file
-   ✔ Fixing .gitignore
-
-   We have ATTEMPTED to convert your app to be in a format that electron-forge understands.
-
-   Thanks for using "electron-forge"!!!
-   ```
-
-3. Create a distributable using Forge's `make` command:
-
-   ```sh npm2yarn
-   npm run make
-
-   > my-electron-app@1.0.0 make /my-electron-app
-   > electron-forge make
-
-   ✔ Checking your system
-   ✔ Resolving Forge Config
-   We need to package your application before we can make it
-   ✔ Preparing to Package Application for arch: x64
-   ✔ Preparing native dependencies
-   ✔ Packaging Application
-   Making for the following targets: zip
-   ✔ Making for target: zip - On platform: darwin - For arch: x64
-   ```
-
-   Electron Forge creates the `out` folder where your package will be located:
-
-   ```plain
-   // Example for macOS
-   out/
-   ├── out/make/zip/darwin/x64/my-electron-app-darwin-x64-1.0.0.zip
-   ├── ...
-   └── out/my-electron-app-darwin-x64/my-electron-app.app/Contents/MacOS/my-electron-app

+### 20. Do not expose Electron APIs to untrusted web content
+
+You should not directly expose Electron's APIs, especially IPC, to untrusted web content in your
+preload scripts.
+
+### Why?
+
+Exposing raw APIs like `ipcRenderer.on` is dangerous because it gives renderer processes direct
+access to the entire IPC event system, allowing them to listen for any IPC events, not just the ones
+intended for them.
+
+To avoid that exposure, we also cannot pass callbacks directly through: The first
+argument to IPC event callbacks is an `IpcRendererEvent` object, which includes properties like `sender`
+that provide access to the underlying `ipcRenderer` instance. Even if you only listen for specific
+events, passing the callback directly means the renderer gets access to this event object.
+
+In short, we want the untrusted web content to only have access to necessary information and APIs.
+
+### How?
+
+```js title='preload'.js'

 # Window Customization
 
-The `BrowserWindow` module is the foundation of your Electron application, and it exposes
-many APIs that can change the look and behavior of your browser windows. In this
-tutorial, we will be going over the various use-cases for window customization on
-macOS, Windows, and Linux.
+The [`BrowserWindow`][] module is the foundation of your Electron application, and
+it exposes many APIs that let you customize the look and behavior of your app’s windows.
+This section covers how to implement various use cases for window customization on macOS,
+Windows, and Linux.
 
-## Create frameless windows
+> [!NOTE]
+> `BrowserWindow` is a subclass of the [`BaseWindow`][] module. Both modules allow
+> you to create and manage application windows in Electron, with the main difference
+> being that `BrowserWindow` supports a single, full size web view while `BaseWindow`
+> supports composing many web views. `BaseWindow` can be used interchangeably with `BrowserWindow`
+> in the examples of the documents in this section.
 
-A frameless window is a window that has no [chrome][]. Not to be confused with the Google
-Chrome browser, window _chrome_ refers to the parts of the window (e.g. toolbars, controls)
-that are not a part of the web page.
+ <!-- markdownlint-disable-next-line MD033 -->
+<DocCardList />
 
-To create a frameless window, you need to set `frame` to `false` in the `BrowserWindow`
-constructor.
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ frame: false })
-```
-
-## Apply custom title bar styles _macOS_ _Windows_
-
-Title bar styles allow you to hide most of a BrowserWindow's chrome while keeping the
-system's native window controls intact and can be configured with the `titleBarStyle`
-option in the `BrowserWindow` constructor.
-
-Applying the `hidden` title bar style results in a hidden title bar and a full-size
-content window.
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'hidden' })
-```
-
-### Control the traffic lights _macOS_
-
-On macOS, applying the `hidden` title bar style will still expose the standard window
-controls (“traffic lights”) in the top left.
-
-#### Customize the look of your traffic lights _macOS_
-
-The `customButtonsOnHover` title bar style will hide the traffic lights until you hover
-over them. This is useful if you want to create custom traffic lights in your HTML but still
-use the native UI to control the window.
-
-```js
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'customButtonsOnHover' })
-```
-
-#### Customize the traffic light position _macOS_
-
-To modify the position of the traffic light window controls, there are two configuration
-options available.
-
-Applying `hiddenInset` title bar style will shift the vertical inset of the traffic lights
-by a fixed amount.
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'hiddenInset' })
-```
-
-If you need more granular control over the positioning of the traffic lights, you can pass
-a set of coordinates to the `trafficLightPosition` option in the `BrowserWindow`
-constructor.
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({
-  titleBarStyle: 'hidden',
-  trafficLightPosition: { x: 10, y: 10 }
-})
-```
-
-#### Show and hide the traffic lights programmatically _macOS_
-
-You can also show and hide the traffic lights programmatically from the main process.
-The `win.setWindowButtonVisibility` forces traffic lights to be show or hidden depending
-on the value of its boolean parameter.
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow()
-// hides the traffic lights
-win.setWindowButtonVisibility(false)
-```
-
-> Note: Given the number of APIs available, there are many ways of achieving this. For instance,
-> combining `frame: false` with `win.setWindowButtonVisibility(true)` will yield the same
-> layout outcome as setting `titleBarStyle: 'hidden'`.
-
-## Window Controls Overlay
-
-The [Window Controls Overlay API][] is a web standard that gives web apps the ability to
-customize their title bar region when installed on desktop. Electron exposes this API
-through the `BrowserWindow` constructor option `titleBarOverlay`.
-
-This option only works whenever a custom `titlebarStyle` is applied.
-When `titleBarOverlay` is enabled, the window controls become exposed in their default
-position, and DOM elements cannot use the area underneath this region.
-
-The `titleBarOverlay` option accepts two different value formats.
-
-Specifying `true` on either platform will result in an overlay region with default
-system colors:
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({
-  titleBarStyle: 'hidden',
-  titleBarOverlay: true
-})
-```
-
-On either platform `titleBarOverlay` can also be an object. The height of the overlay can be specified with the `height` property. On Windows and Linux, the color of the overlay and can be specified using the `color` property. On Windows and Linux, the color of the overlay and its symbols can be specified using the `color` and `symbolColor` properties respectively. The `rgba()`, `hsla()`, and `#RRGGBBAA` color formats are supported to apply transparency.
-
-If a color option is not specified, the color will default to its system color for the window control buttons. Similarly, if the height option is not specified it will default to the default height:
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({
-  titleBarStyle: 'hidden',
-  titleBarOverlay: {
-    color: '#2f3241',
-    symbolColor: '#74b1be',
-    height: 60
-  }
-})
-```
-
-> Note: Once your title bar overlay is enabled from the main process, you can access the overlay's
-> color and dimension values from a renderer using a set of readonly
-> [JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars].
-
-## Create transparent windows
-
-By setting the `transparent` option to `true`, you can make a fully transparent window.
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ transparent: true })
-```
-
-### Limitations
-
-* You cannot click through the transparent area. See
-  [#1335](https://github.com/electron/electron/issues/1335) for details.
-* Transparent windows are not resizable. Setting `resizable` to `true` may make
-  a transparent window stop working on some platforms.
-* The CSS [`blur()`][] filter only applies to the window's web contents, so there is no way to apply
-  blur effect to the content below the window (i.e. other applications open on
-  the user's system).
-* The window will not be transparent when DevTools is opened.
-* On _Windows_:
-  * Transparent windows will not work when DWM is disabled.
-  * Transparent windows can not be maximized using the Windows system menu or by double
-  clicking the title bar. The reasoning behind this can be seen on
-  PR [#28207](https://github.com/electron/electron/pull/28207).
-* On _macOS_:
-  * The native window shadow will not be shown on a transparent window.
-
-## Create click-through windows
-
-To create a click-through window, i.e. making the window ignore all mouse
-events, you can call the [win.setIgnoreMouseEvents(ignore)][ignore-mouse-events]
-API:
-
-```js title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow()
-win.setIgnoreMouseEvents(true)
-```
-
-### Forward mouse events _macOS_ _Windows_
-
-Ignoring mouse messages makes the web contents oblivious to mouse movement,
-meaning that mouse movement events will not be emitted. On Windows and macOS, an
-optional parameter can be used to forward mouse move messages to the web page,
-allowing events such as `mouseleave` to be emitted:
-
-```js title='main.js'
-const { BrowserWindow, ipcMain } = require('electron')
-const path = require('node:path')
-
-const win = new BrowserWindow({
-  webPreferences: {
-    preload: path.join(__dirname, 'preload.js')
-  }
-})
-
-ipcMain.on('set-ignore-mouse-events', (event, ignore, options) => {
-  const win = BrowserWindow.fromWebContents(event.sender)
-  win.setIgnoreMouseEvents(ignore, options)
-})
-```
-
-```js title='preload.js'
-window.addEventListener('DOMContentLoaded', () => {
-  const el = document.getElementById('clickThroughElement')
-  el.addEventListener('mouseenter', () => {
-    ipcRenderer.send('set-ignore-mouse-events', true, { forward: true })
-  })
-  el.addEventListener('mouseleave', () => {
-    ipcRenderer.send('set-ignore-mouse-events', false)
-  })
-})
-```
-
-This makes the web page click-through when over the `#clickThroughElement` element,
-and returns to normal outside it.
-
-## Set custom draggable region
-
-By default, the frameless window is non-draggable. Apps need to specify
-`-webkit-app-region: drag` in CSS to tell Electron which regions are draggable
-(like the OS's standard titlebar), and apps can also use
-`-webkit-app-region: no-drag` to exclude the non-draggable area from the
- draggable region. Note that only rectangular shapes are currently supported.
-
-To make the whole window draggable, you can add `-webkit-app-region: drag` as
-`body`'s style:
-
-```css title='styles.css'
-body {
-  -webkit-app-region: drag;
-}
-```
-
-And note that if you have made the whole window draggable, you must also mark
-buttons as non-draggable, otherwise it would be impossible for users to click on
-them:
-
-```css title='styles.css'
-button {
-  -webkit-app-region: no-drag;
-}
-```
-
-If you're only setting a custom titlebar as draggable, you also need to make all
-buttons in titlebar non-draggable.
-
-### Tip: disable text selection
-
-When creating a draggable region, the dragging behavior may conflict with text selection.
-For example, when you drag the titlebar, you may accidentally select its text contents.
-To prevent this, you need to disable text selection within a draggable area like this:
-
-```css
-.titlebar {
-  -webkit-user-select: none;
-  -webkit-app-region: drag;
-}
-```
-
-### Tip: disable context menus
-
-On some platforms, the draggable area will be treated as a non-client frame, so
-when you right click on it, a system menu will pop up. To make the context menu
-behave correctly on all platforms, you should never use a custom context menu on
-draggable areas.

+# Why Electron
+
+Electron is a framework enabling developers to build cross-platform desktop applications for macOS, Windows, and Linux by combining web technologies (HTML, JavaScript, CSS) with Node.js and native code. It is open-source, MIT-licensed, and free for both commercial and personal use. In this document, we’ll explain why companies and developers choose Electron.
+
+We can split up the benefits of Electron in two questions: First, why should you use web technologies to build your application? Then, why should you choose Electron as the framework to do so?
+
+If you’re already using web technologies for your application, you can skip straight to the `Why Electron?` section below.
+
+## Why choose web technologies
+
+Web technologies include HTML, CSS, JavaScript, and WebAssembly. They’re the storefront of the modern Internet. Those technologies have emerged as the best choice for building user interfaces — both for consumer applications as well as mission-critical business applications. This is true both for applications that need to run in a browser as well as desktop applications that are not accessible from a browser. Our bold claim here is that this isn’t just true for cross-platform applications that need to run on multiple operating systems but true overall.
+
+As an example, NASA’s actual [Mission Control](https://github.com/nasa/openmct) is written with web technologies. The [Bloomberg Terminal](https://en.wikipedia.org/wiki/Bloomberg_Terminal), the computer system found at every financial institution, is written with web technologies and runs inside Chromium. It costs $25,000 per user, per year. The McDonald’s ordering kiosk, powering the world’s biggest food retailer, is entirely built with Chromium. The [SpaceX’s Dragon 2 space capsule](https://old.reddit.com/r/spacex/comments/gxb7j1/we_are_the_spacex_software_team_ask_us_anything/ft62781/?context=3) uses Chromium to display its interface. You get the point: web technologies are a great tech stack to build user interfaces.
+
+Here are the reasons we, the Electron maintainers, are betting on the web.
+
+### Versatility
+
+Modern versions of HTML and CSS enable your developers and designers to fully express themselves. The web’s showcase includes Google Earth, Netflix, Spotify, Gmail, Facebook, Airbnb, or GitHub. Whatever interface your application needs, you will be able to express it with HTML, CSS, and JavaScript.
+
+If you want to focus on building a great product without figuring out how you can realize your designer’s vision in a specific UI framework, the web is a safe bet.
+
+### Reliability
+
+Web technologies are the most-used foundation for user interfaces on the planet. The have been hardened accordingly. Modern computers have been optimized from the CPU to the operating system to be good at running web technologies. The manufacturers of your user’s devices—be that an Android phone or the latest MacBook—will ensure that they can visit websites, play videos on YouTube, or display emails. In turn, they’ll also ensure that your app has a stable foundation, even if you have just one user.
+
+If you want to focus on building a great product without debugging a weird quirk that nobody has found before, the web is a safe bet.
+
+### Interoperability
+
+Whatever provider or customer data you need to interact with, they will have probably thought of an integration path with the web. Depending on your technology choice, embedding a YouTube video either takes 30 seconds or requires you to hire a team devoted to streaming and hardware-accelerated video decoding. In the case of YouTube, using anything other than the provided players is actually against their terms and conditions, so you’ll likely embed a browser frame before you implement your own video streaming decoder.
+
+There will be virtually no platform where your app cannot run if you build it with web technologies. Virtually all devices with a display—be that an ATM, a car infotainment system, a smart TV, a fridge, or a Nintendo Switch—come with means to display web technologies. The web is safe bet if you want to be cross-platform.
+
+### Ubiquity
+
+It’s easy to find developers with experience building with web technologies. If you’re a developer, it’ll be easy to find answers to your questions on Google, Stack Overflow, GitHub, or a coding AI of your choice. Whatever problem you need to solve, it’s likely that somebody has solved it well before—and that you can find the answer to the puzzle online.
+
+If you want to focus on building a great product with ample access to resources and materials, the web is a safe bet.
+
+## Why choose Electron
+
+Electron combines Chromium, Node.js, and the ability to write custom native code into one framework for building powerful desktop applications. There are three main reasons to use Electron:
+
+### Enterprise-grade
+
+Electron is reliable, secure, stable, and mature. It is the premier choice for companies building their flagship product. We have a list of some of those companies on our homepage, but just among chat apps, Slack, Discord, and Skype are built with Electron. Among AI applications, both OpenAI’s ChatGPT and Anthropic’s Claude use Electron. Visual Studio Code, Loom, Canva, Notion, Docker, and countless other leading developers of software bet on Electron.
+
+We did make it a priority to make Electron easy to work with and a delight for developers. That’s likely the main reason why Electron became as popular as it is today — but what keeps Electron alive and thriving is the maintainer’s focus on making Electron as stable, secure, performant, and capable of mission-critical use cases for end users as possible. We’re building an Electron that is ready to be used in scenarios where unfixable bugs, unpatched security holes, and outages of any kind are worst-case scenarios.
+
+### Mature
+
+Our current estimation is that most desktop computers on the planet run at least one Electron app. Electron has grown by prioritizing talent in its maintainer group, fostering excellent and sustainable engineering practices in managing the ongoing maintenance, and proactively inviting companies betting on Electron to directly contribute to the project. We’re an impact project with the OpenJS foundation, which is itself a part of the Linux foundation. We share resources and expertise with other foundation projects like Node.js, ESLint, Webpack - or the Linux Kernel or Kubernetes.
+
+What does all of that mean for you, a developer, in practice?
+
+- **Reliable release schedule**: Electron will release a new major version in lockstep with every second major Chromium release, usually on the same day as Chromium. A lot of work, both in the form of building processes and tools, but also in terms of raw invested hours every week, has to go into making that happen.
+- **No dictators**: Sometimes, betting on a technology also requires you to bet on a single person or company. In turn, it requires you to trust that the person or company never has a breakdown, starts fighting you directly, or does anything else drastic that’ll force you rethink your entire tech stack. Electron is maintained by a diverse set of companies (Microsoft, Slack/Salesforce, Notion, and more) and will continue to welcome more companies interested in ensuring their “seat at the decision-making table”.
+
+### Stability, security, performance
+
+Electron delivers the best experience on all target platforms (macOS, Windows, Linux) by bundling the latest version of Chromium, V8, and Node.js directly with the application binary. When it comes to running and rendering web content with upmost stability, security, and performance, we currently believe that stack to be “best in class”.
+
+#### Why bundle anything at all
+
+You might wonder why we bundle Chromium’s web stack with our apps when most modern operating systems already ship a browser and some form of web view. Bundling doesn’t just increase the amount of work for Electron maintainers dramatically, it also increases the total disk size of Electron apps (most apps are >100MB). Many Electron maintainers once developed applications that did make use of embedded web views — and have since accepted the increased disk size and maintainer work as a worthy trade-off.
+
+When using an operating system's built-in web view, you're limited by the browser version included in the oldest operating system version you need to support. We have found the following problems with this approach:
+
+- **Stability**: The modern web technology stack is complex, and as a result, you’ll sooner or later encounter bugs. If you use the operating system’s web view, your only recourse will be to ask your customers to upgrade their operating system. If no upgrade is available for that machine (because of no ability to upgrade to the latest macOS or Windows 11), you’ll have to ask them to buy a new computer. If you’re unlucky, you’re now losing a major customer because they will not upgrade their entire fleet of thousands of machines just because one team wanted to try your startup’s app. You have _no recourse_ in this situation. Even the risk of that happening is unacceptable to the companies that employ the Electron maintainers.
+- **Security:** Similar to how you can fix stability bugs by releasing an app update, you can also release security fixes to your application without asking your customer to upgrade their operating system. Even if operating system providers prioritize updates to their built-in browser, we have not seen them reliably update the built-in web views with similar urgency. Bundling a web renderer gives you, the developer, control.
+- **Performance:** For simple HTML documents, a built-in web view will sometimes use fewer resources than an app with a bundled framework. For bigger apps, it is our experience that we can deliver better performance with the latest version of Chromium than we can with built-in web views. You might think that the built-in view can share a lot of resources with other apps and the operating system— but for security reasons, apps have to run in their own sandboxes, isolated from each other. At that point, the question is whether the OS’ web view is more performant than Chromium. Across many apps, our experience is that bundling Chromium and Node.js enables us to build better and more performant experiences.
+
+#### Why bundle Chromium and Node.js
+
+Electron aims to enable the apps it supports to deliver the best possible user experience, followed by the best possible developer experience. Chromium is currently the best cross-platform rendering stack available. Node.js uses Chromium’s JavaScript engine V8, allowing us to combine the powers of both.
+
+- **Native code when you want it**: Thanks to Node.js’ mature native addon system, you can always write native code. There is no system API out of reach for you. Whatever macOS, Windows, or Linux feature you’ll want to integrate with —as long as you can do it in C, C++, Objective-C, Rust, or another native language, you’ll be able to do it in Electron. Again, this gives you, the developer, maximum control. With Electron, you can use web technologies without choosing _only_ web technologies.
+
+### Developer experience
+
+To summarize, we aim to build an Electron that is mature, enterprise-grade, and ready for mission-critical applications. We prioritize reliability, stability, security, and performance. That said, you might also choose Electron for its developer experience:
+
+- **Powerful ecosystem**: Anything you find on npm will run inside Electron. Any resource available to you about how to work with Node.js also applies to Electron. In addition, Electron itself has a [thriving ecosystem](https://www.npmjs.com/search?q=electron) — including plenty of choices for installers, updaters, deeper operating system-integration, and more.
+- **Plenty of built-in capabilities:** Over the last ten years, Electron’s core has gained plenty of native capabilities that you might need to build your application. Written in C++ and Objective-C, Electron has [dozens of easy-to-use APIs for deeper operating-system integration](https://www.electronjs.org/docs/latest/api/app) — like advanced window customization for transparent or oddly shaped widgets, receiving push notifications from the Apple Push Notification Network, or handling a custom URL protocol for your app.
+- **Open source**: The entire stack is open source and open to your inspection. This ensures your freedom to add any feature or fix any bug you might encounter in the future.
+- **Native code when you need it:** It bears repeating that Electron allows you to mix and match web technologies and C++, C, Objective-C, Rust, and other native languages. Whether it be SQLite, a whole LLM, or just the ability to call one specific native API, Electron will make it easy.
+
+---
+
+## Why choose something else
+
+As outlined above, the web is an amazing platform for building interfaces. That doesn’t mean that we, the maintainers, would build _everything_ with HTML and CSS. Here are some notable exceptions:
+
+**Resource-Constrained Environments and IoT:** In scenarios with very limited memory or processing power (say, one megabyte of memory and 100MHz of processing power on a low-powered ARM Cortex-M), you will likely need to use a low-level language to directly talk to the display to output basic text and images. Even on slightly higher-powered single-chip devices you might want to consider an embedded UI framework. A classic example is a smart watch.
+
+**Small Disk Footprint**: Zipped Electron apps are usually around 80 to 100 Megabytes. If a smaller disk footprint is a hard requirement, you’ll have to use something else.
+
+**Operating System UI Frameworks and Libraries**: By allowing you to write native code, Electron can do anything a native application can do, including the use of the operating system’s UI components, like WinUI, SwiftUI, or AppKit. In practice, most Electron apps make rare use of that ability. If you want the majority of your app to be built with operating system-provided interface components, you’ll likely be better off building fully native apps for each operating system you’d like to target. It’s not that it’s impossible with Electron, it’ll just likely be an overall easier development process.
+
+**Games and Real-Time Graphics:** If you're building a high-performance game or application requiring complex real-time 3D graphics, native frameworks like Unity, Unreal Engine, or DirectX/OpenGL will provide better performance and more direct access to graphics hardware. Web fans might point out caveats, like the fact that even Unreal Engine ships with Chromium — or that WebGPU and WebGL are developing rapidly and many game engines, including the ones listed here, can now output their games in a format that runs in a browser. That said, if you asked us to build the next AAA game, we’d likely use something else than just web technologies.
+
+**Embedding Lightweight Websites**: Electron apps typically are mostly web apps with native code sprinkled in where useful. Processing-heavy Electron applications tend to write the UI in HTML/CSS and build the backend in Rust, C++, or another native language. If you’re planning to build a primarily native application that also wants to display a little website in a specific view, you might be better off using the OS-provided web view or something like [ultralight](https://ultralig.ht/).
