+### Using electron-wix-msi (WiX MSI)
+
+[`electron-wix-msi`] is a package that can generate MSI installers for your
+Electron app. This is the tool used under the hood by Electron Forge's [MSI Maker][maker-msi].
+
+If you're not using Electron Forge and want to use `electron-wix-msi` directly, use the
+`certificateFile` and `certificatePassword` configuration options
+or pass in parameters directly to [SignTool.exe] with the `signWithParams` option.
+
+```js {12-13}
+import { MSICreator } from 'electron-wix-msi'
+
+// Step 1: Instantiate the MSICreator
+const msiCreator = new MSICreator({
+  appDirectory: '/path/to/built/app',
+  description: 'My amazing Kitten simulator',
+  exe: 'kittens',
+  name: 'Kittens',
+  manufacturer: 'Kitten Technologies',
+  version: '1.1.2',
+  outputDirectory: '/path/to/output/folder',
+  certificateFile: './cert.pfx',
+  certificatePassword: 'this-is-a-secret',
+})
+
+// Step 2: Create a .wxs template file
+const supportBinaries = await msiCreator.create()
+
+// 🆕 Step 2a: optionally sign support binaries if you
+// sign you binaries as part of of your packaging script
+supportBinaries.forEach(async (binary) => {
+  // Binaries are the new stub executable and optionally
+  // the Squirrel auto updater.
+  await signFile(binary)
+})
+
+// Step 3: Compile the template to a .msi file
+await msiCreator.compile()
+```

+slug: distribution-overview
+hide_title: false
+---
+
+Once your app is ready for production, there are a couple steps you need to take before
+you can deliver it to your users.
+
+## Packaging
+
+To distribute your app with Electron, you need to package all your resources and assets
+into an executable and rebrand it. To do this, you can either use specialized tooling
+or do it manually. See the [Application Packaging][application-packaging] tutorial
+for more information.
+
+## Code signing
+
+Code signing is a security technology that you use to certify that an app was
+created by you. You should sign your application so it does not trigger the
+security checks of your user's operating system.
+
+To get started with each operating system's code signing process, please read the
+[Code Signing][code-signing] docs.
+
+## Publishing
+
+Once your app is packaged and signed, you can freely distribute your app directly
+to users by uploading your installers online.
+
+To reach more users, you can also choose to upload your app to each operating system's
+digital distribution platform (i.e. app store). These require another build step aside
+from your direct download app. For more information, check out each individual app store guide:
+
+- [Mac App Store][mac-app]
+- [Windows Store][windows-store]
+- [Snapcraft (Linux)][snapcraft]
+
+## Updating
+
+Electron's auto-updater allows you to deliver application updates to users
+without forcing them to manually download new versions of your application.
+Check out the [Updating Applications][updates] guide for details on implementing automatic updates
+with Electron.

+
+In this section, we have collected a set of guides for common features
+that you may want to implement in your Electron application. Each guide
+contains a practical example in a minimal, self-contained example app.
+The easiest way to run these examples is by downloading [Electron Fiddle][fiddle].
+
+Once Fiddle is installed, you can press on the "Open in Fiddle" button that you
+will find below code samples like the following one:
+
+```fiddle docs/fiddles/quick-start
+window.addEventListener('DOMContentLoaded', () => {
+  const replaceText = (selector, text) => {
+    const element = document.getElementById(selector)
+    if (element) element.innerText = text
+  }
+
+  for (const type of ['chrome', 'node', 'electron']) {
+    replaceText(`${type}-version`, process.versions[type])
+  }
+})
+```

+Electron is a framework for building desktop applications using JavaScript,
+HTML, and CSS. By embedding [Chromium][chromium] and [Node.js][node] into a
+single binary file, Electron allows you to create cross-platform apps that
+work on Windows, macOS, and Linux with a single JavaScript codebase.
+
+This tutorial will guide you through the process of developing a desktop
+application with Electron and distributing it to end users.
+
+## Assumptions
+
+Electron is a native wrapper layer for web apps and is run in a Node.js environment.
+Therefore, this tutorial assumes you are generally familiar with Node and
+front-end web development basics. If you need to do some background reading before
+continuing, we recommend the following resources:
+
+- [Getting started with the Web (MDN Web Docs)][mdn-guide]
+- [Introduction to Node.js][node-guide]
+
+## Required tools
+
+### Code editor
+
+You will need a text editor to write your code. We recommend using [Visual Studio Code],
+although you can choose whichever one you prefer.
+
+### Command line
+
+Throughout the tutorial, we will ask you to use various command-line interfaces (CLIs). You can
+type these commands into your system's default terminal:
+
+- Windows: Command Prompt or PowerShell
+- macOS: Terminal
+- Linux: varies depending on distribution (e.g. GNOME Terminal, Konsole)
+
+Most code editors also come with an integrated terminal, which you can also use.
+
+### Git and GitHub
+
+Git is a commonly-used version control system for source code, and GitHub is a collaborative
+development platform built on top of it. Although neither is strictly necessary to building
+an Electron application, we will use GitHub releases to set up automatic updates later
+on in the tutorial. Therefore, we'll require you to:
+
+- [Create a GitHub account](https://github.com/join)
+- [Install Git](https://github.com/git-guides/install-git)
+
+If you're unfamiliar with how Git works, we recommend reading GitHub's [Git guides]. You can also
+use the [GitHub Desktop] app if you prefer using a visual interface over the command line.
+
+We recommend that you create a local Git repository and publish it to GitHub before starting
+the tutorial, and commit your code after every step.
+
+:::info Installing Git via GitHub Desktop
+
+GitHub Desktop will install the latest version of Git on your system if you don't already have
+it installed.
+
+:::
+
+### Node.js and npm
+
+To begin developing an Electron app, you need to install the [Node.js][node-download]
+runtime and its bundled npm package manager onto your system. We recommend that you
+use the latest long-term support (LTS) version.
+
+:::tip
+
+Please install Node.js using pre-built installers for your platform.
+You may encounter incompatibility issues with different development tools otherwise.
+If you are using macOS, we recommend using a package manager like [Homebrew] or
+[nvm] to avoid any directory permission issues.
+
+:::
+
+To check that Node.js was installed correctly, you can use the `-v` flag when
+running the `node` and `npm` commands. These should print out the installed
+versions.
+
+```sh
+$ node -v
+v16.14.2
+$ npm -v
+8.7.0
+```
+
+:::caution
+
+Although you need Node.js installed locally to scaffold an Electron project,
+Electron **does not use your system's Node.js installation to run its code**. Instead, it
+comes bundled with its own Node.js runtime. This means that your end users do not
+need to install Node.js themselves as a prerequisite to running your app.
+
+To check which version of Node.js is running in your app, you can access the global
+[`process.versions`] variable in the main process or preload script. You can also reference
+the list of versions in the [electron/releases] repository.

+
+## Learning goals
+
+In this part of the tutorial, you will learn how to set up your Electron project
+and write a minimal starter application. By the end of this section,
+you should be able to run a working Electron app in development mode from
+your terminal.
+
+## Setting up your project
+
+:::caution Avoid WSL
+
+If you are on a Windows machine, please do not use [Windows Subsystem for Linux][wsl] (WSL)
+when following this tutorial as you will run into issues when trying to execute the
+application.
+
+<!--https://www.electronforge.io/guides/developing-with-wsl-->
+
+:::
+
+### Initializing your npm project
+
+Electron apps are scaffolded using npm, with the package.json file
+as an entry point. Start by creating a folder and initializing an npm package
+within it with `npm init`.
+
+```sh npm2yarn
+mkdir my-electron-app && cd my-electron-app
+npm init
+```
+
+This command will prompt you to configure some fields in your package.json.
+There are a few rules to follow for the purposes of this tutorial:
+
+- _entry point_ should be `main.js` (you will be creating that file soon).
+- _author_, _license_, and _description_ can be any value, but will be necessary for
+  [packaging][packaging] later on.
+
+Then, install Electron into your app's **devDependencies**, which is the list of external
+development-only package dependencies not required in production.
+
+:::info Why is Electron a devDependency?
+
+This may seem counter-intuitive since your production code is running Electron APIs.
+However, packaged apps will come bundled with the Electron binary, eliminating the need to specify
+it as a production dependency.
+
+:::
+
+```sh npm2yarn
+npm install electron --save-dev
+```
+
+Your package.json file should look something like this after initializing your package
+and installing Electron. You should also now have a `node_modules` folder containing
+the Electron executable, as well as a `package-lock.json` lockfile that specifies
+the exact dependency versions to install.
+
+```json title='package.json'
+{
+  "name": "my-electron-app",
+  "version": "1.0.0",
+  "description": "Hello World!",
+  "main": "main.js",
+  "author": "Jane Doe",
+  "license": "MIT",
+  "devDependencies": {
+    "electron": "19.0.0"
+  }
+}
+```
+
+:::info Advanced Electron installation steps
+
+If installing Electron directly fails, please refer to our [Advanced Installation][installation]
+documentation for instructions on download mirrors, proxies, and troubleshooting steps.
+
+:::
+
+### Adding a .gitignore
+
+The [`.gitignore`][gitignore] file specifies which files and directories to avoid tracking
+with Git. You should place a copy of [GitHub's Node.js gitignore template][gitignore-template]
+into your project's root folder to avoid committing your project's `node_modules` folder.
+
+## Running an Electron app
+
+:::tip Further reading
+
+Read [Electron's process model][process-model] documentation to better
+understand how Electron's multiple processes work together.
+
+:::
+
+The [`main`][package-json-main] script you defined in package.json is the entry point of any
+Electron application. This script controls the **main process**, which runs in a 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).
+
+Before creating your first Electron app, you will first use a trivial script to ensure your
+main process entry point is configured correctly. Create a `main.js` file in the root folder
+of your project with a single line of code:
+
+```js title='main.js'
+console.log(`Hello from Electron 👋`)
+```
+
+Because Electron's main process is a Node.js runtime, you can execute arbitrary Node.js code
+with the `electron` command (you can even use it as a [REPL]). To execute this script,
+add `electron .` to the `start` command in the [`scripts`][package-scripts]
+field of your package.json. This command will tell the Electron executable to look for the main
+script in the current directory and run it in dev mode.
+
+```json {8-10} title='package.json'
+{
+  "name": "my-electron-app",
+  "version": "1.0.0",
+  "description": "Hello World!",
+  "main": "main.js",
+  "author": "Jane Doe",
+  "license": "MIT",
+  "scripts": {
+    "start": "electron ."
+  },
+  "devDependencies": {
+    "electron": "^19.0.0"
+  }
+}
+```
+
+```sh npm2yarn
+npm run start
+```
+
+Your terminal should print out `Hello from Electron 👋`. Congratulations,
+you have executed your first line of code in Electron! Next, you will learn
+how to create user interfaces with HTML and load that into a native window.
+
+## Loading a web page into a BrowserWindow
+
+In Electron, each window displays a web page that can be loaded either from a local HTML
+file or a remote web address. For this example, you will be loading in a local file. Start
+by creating a barebones web page in an `index.html` file in the root folder of your project:
+
+```html title='index.html'
+<!DOCTYPE html>
+<html>
+  <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'"
+    />
+    <meta
+      http-equiv="X-Content-Security-Policy"
+      content="default-src 'self'; script-src 'self'"
+    />
+    <title>Hello from Electron renderer!</title>
+  </head>
+  <body>
+    <h1>Hello from Electron renderer!</h1>
+    <p>👋</p>
+  </body>
+</html>
+```
+
+Now that you have a web page, you can load it into an Electron [BrowserWindow][browser-window].
+Replace the contents your `main.js` file with the following code. We will explain each
+highlighted block separately.
+
+```js {1,3-10,12-14} title='main.js' showLineNumbers
+const { app, BrowserWindow } = require('electron')
+
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+  })
+
+  win.loadFile('index.html')
+}
+
+app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+### Importing modules
+
+```js title='main.js (Line 1)'
+const { app, BrowserWindow } = require('electron')
+```
+
+In the first line, we are importing two Electron modules
+with CommonJS module syntax:
+
+- [app][app], which controls your application's event lifecycle.
+- [BrowserWindow][browser-window], which creates and manages app windows.
+
+:::info Capitalization conventions
+
+You might have noticed the capitalization difference between the **a**pp
+and **B**rowser**W**indow modules. Electron follows typical JavaScript conventions here,
+where PascalCase modules are instantiable class constructors (e.g. BrowserWindow, Tray,
+Notification) whereas camelCase modules are not instantiable (e.g. app, ipcRenderer, webContents).
+
+:::
+
+:::warning ES Modules in Electron
+
+[ECMAScript modules](https://nodejs.org/api/esm.html) (i.e. using `import` to load a module)
+are currently not directly supported in Electron. You can find more information about the
+state of ESM in Electron in [electron/electron#21457](https://github.com/electron/electron/issues/21457).
+
+:::
+
+### Writing a reusable function to instantiate windows
+
+The `createWindow()` function loads your web page into a new BrowserWindow instance:
+
+```js title='main.js (Lines 3-10)'
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+  })
+
+  win.loadFile('index.html')
+}
+```
+
+### Calling your function when the app is ready
+
+```js title='main.js (Lines 12-14)'
+app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+Many of Electron's core modules are Node.js [event emitters] that adhere to Node's asynchronous
+event-driven architecture. The app module is one of these emitters.
+
+In Electron, BrowserWindows 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 and
+calling `createWindow()` once its promise is fulfilled.
+
+:::info
+
+You typically listen to Node.js events by using an emitter's `.on` function.
+
+```diff
++ app.on('ready').then(() => {
+- app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+However, Electron exposes `app.whenReady()` as a helper specifically for the `ready` event to
+avoid subtle pitfalls with directly listening to that event in particular.
+See [electron/electron#21972](https://github.com/electron/electron/pull/21972) for details.
+
+:::
+
+At this point, running your Electron application's `start` command should successfully
+open a window that displays your web page!
+
+Each web page your app displays in a window will run in a separate process called a
+**renderer** process (or simply _renderer_ for short). Renderer processes have access
+to the same JavaScript APIs and tooling you use for typical front-end web
+development, such as using [webpack] to bundle and minify your code or [React][react]
+to build your user interfaces.
+
+## Managing your app's window lifecycle
+
+Application windows behave differently on each operating system. Rather than
+enforce these conventions by default, Electron gives you the choice to implement
+them in your app code if you wish to follow them. You can implement basic window
+conventions by listening for events emitted by the app and BrowserWindow modules.
+
+:::tip Process-specific control flow
+
+Checking against Node's [`process.platform`][node-platform] variable can help you
+to run code conditionally on certain platforms. Note that there are only three
+possible platforms that Electron can run in: `win32` (Windows), `linux` (Linux),
+and `darwin` (macOS).
+
+:::
+
+### Quit the app when all windows are closed (Windows & Linux)
+
+On Windows and Linux, closing all windows will generally quit an application entirely.
+To implement this pattern in your Electron app, listen for the app module's
+[`window-all-closed`][window-all-closed] event, and call [`app.quit()`][app-quit]
+to exit your app if the user is not on macOS.
+
+```js
+app.on('window-all-closed', () => {
+  if (process.platform !== 'darwin') app.quit()
+})
+```
+
+### Open a window if none are open (macOS)
+
+In contrast, macOS apps generally continue running even without any windows open.
+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 BrowserWindows 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 only listening for activate
+events inside your existing `whenReady()` callback.
+
+```js
+app.whenReady().then(() => {
+  createWindow()
+
+  app.on('activate', () => {
+    if (BrowserWindow.getAllWindows().length === 0) createWindow()
+  })
+})
+```
+
+## Final starter code
+
+```fiddle docs/fiddles/tutorial-first-app
+
+```
+
+## Optional: Debugging from VS Code
+
+If you want to debug your application using VS Code, you have need attach VS Code to
+both the main and renderer processes. Here is a sample configuration for you to
+run. Create a launch.json configuration in a new `.vscode` folder in your project:
+
+```json title='.vscode/launch.json'
+{
+  "version": "0.2.0",
+  "compounds": [
+    {
+      "name": "Main + renderer",
+      "configurations": ["Main", "Renderer"],
+      "stopAll": true
+    }
+  ],
+  "configurations": [
+    {
+      "name": "Renderer",
+      "port": 9222,
+      "request": "attach",
+      "type": "pwa-chrome",
+      "webRoot": "${workspaceFolder}"
+    },
+    {
+      "name": "Main",
+      "type": "pwa-node",
+      "request": "launch",
+      "cwd": "${workspaceFolder}",
+      "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron",
+      "windows": {
+        "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron.cmd"
+      },
+      "args": [".", "--remote-debugging-port=9222"],
+      "outputCapture": "std",
+      "console": "integratedTerminal"
+    }
+  ]
+}
+```
+
+The "Main + renderer" option will appear when you select "Run and Debug"
+from the sidebar, allowing you to set breakpoints and inspect all the variables among
+other things in both the main and renderer processes.
+
+What we have done in the `launch.json` file is to create 3 configurations:
+
+- `Main` is used to start the main process and also expose port 9222 for remote debugging
+  (`--remote-debugging-port=9222`). This is the port that we will use to attach the debugger
+  for the `Renderer`. Because the main process is a Node.js process, the type is set to
+  `pwa-node` (`pwa-` is the prefix that tells VS Code to use the latest JavaScript debugger).
+- `Renderer` is used to debug the renderer process. Because the main process is the one
+  that creates the process, we have to "attach" to it (`"request": "attach"`) instead of
+  creating a new one.
+  The renderer process is a web one, so the debugger we have to use is `pwa-chrome`.
+- `Main + renderer` is a [compound task] that executes the previous ones simultaneously.
+
+:::caution
+
+Because we are attaching to a process in `Renderer`, it is possible that the first lines of
+your code will be skipped as the debugger will not have had enough time to connect before they are
+being executed.
+You can work around this by refreshing the page or setting a timeout before executing the code
+in development mode.
+
+:::
+
+:::info Further reading
+
+If you want to dig deeper in the debugging area, the following guides provide more information:
+
+- [Application Debugging]
+- [DevTools Extensions][devtools extension]
+
+:::
+
+## Summary
+
+Electron applications are set up using npm packages. The Electron executable should be installed
+in your project's `devDependencies` and can be run in development mode using a script in your
+package.json file.
+
+The executable runs the JavaScript entry point found in the `main` property of your package.json.
+This file controls Electron's **main process**, which runs an instance of Node.js and is
+responsible for your app's lifecycle, displaying native interfaces, performing privileged operations,
+and managing renderer processes.
+
+**Renderer processes** (or renderers for short) are responsible for display graphical content. You can
+load a web page into a renderer by pointing it to either a web address or a local HTML file.
+Renderers behave very similarly to regular web pages and have access to the same web APIs.
+
+In the next section of the tutorial, we will be learning how to augment the renderer process with
+privileged APIs and how to communicate between processes.

+1. **[Using Preload Scripts][preload]**
+1. [Adding Features][features]
+1. [Packaging Your Application][packaging]
+1. [Publishing and Updating][updates]
+
+:::
+
+## Learning goals
+
+In this part of the tutorial, you will learn what a preload script is and how to use one
+to securely expose privileged APIs into the renderer process. You will also learn how to
+communicate between main and renderer processes with Electron's inter-process
+communication (IPC) modules.
+
+## What is a preload script?
+
+Electron's main process is a Node.js environment that has full operating system access.
+On top of [Electron modules][modules], you can also access [Node.js built-ins][node-api],
+as well as any packages installed via npm. On the other hand, renderer processes run web
+pages and do not run Node.js by default for security reasons.
+
+To bridge Electron's different process types together, we will need to use a special script
+called a **preload**.
+
+## Augmenting the renderer with a preload script
+
+A BrowserWindow's preload script runs in a context that has access to both the HTML DOM
+and a Node.js environment. Preload scripts are injected before a web page loads in the renderer,
+similar to a Chrome extension's [content scripts][content-script]. To add features to your renderer
+that require privileged access, you can define [global] objects through the
+[contextBridge][contextbridge] API.
+
+To demonstrate this concept, you will create a preload script that exposes your app's
+versions of Chrome, Node, and Electron into the renderer.
+
+Add a new `preload.js` script that exposes selected properties of Electron's `process.versions`
+object to the renderer process in a `versions` global variable.
+
+```js title="preload.js"
+const { contextBridge } = require('electron')
+
+contextBridge.exposeInMainWorld('versions', {
+  node: () => process.versions.node,
+  chrome: () => process.versions.chrome,
+  electron: () => process.versions.electron,
+  // we can also expose variables, not just functions
+})
+```
+
+To attach this script to your renderer process, pass its path to the
+`webPreferences.preload` option in the BrowserWindow constructor:
+
+```js {8-10} title="main.js"
+const { app, BrowserWindow } = require('electron')
+const path = require('path')
+
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+    webPreferences: {
+      preload: path.join(__dirname, 'preload.js'),
+    },
+  })
+
+  win.loadFile('index.html')
+}
+
+app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+:::info
+
+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.
+
+:::
+
+At this point, the renderer has access to the `versions` global, so let's display that
+information in the window. This variable can be accessed via `window.versions` or simply
+`versions`. Create a `renderer.js` script that uses the [`document.getElementById`]
+DOM API to replace the displayed text for the HTML element with `info` as its `id` property.
+
+```js title="renderer.js"
+const information = document.getElementById('info')
+information.innerText = `This app is using Chrome (v${versions.chrome()}), Node.js (v${versions.node()}), and Electron (v${versions.electron()})`
+```
+
+Then, modify your `index.html` by adding a new element with `info` as its `id` property,
+and attach your `renderer.js` script:
+
+```html {18,20} title="index.html"
+<!DOCTYPE html>
+<html>
+  <head>
+    <meta charset="UTF-8" />
+    <meta
+      http-equiv="Content-Security-Policy"
+      content="default-src 'self'; script-src 'self'"
+    />
+    <meta
+      http-equiv="X-Content-Security-Policy"
+      content="default-src 'self'; script-src 'self'"
+    />
+    <title>Hello from Electron renderer!</title>
+  </head>
+  <body>
+    <h1>Hello from Electron renderer!</h1>
+    <p>👋</p>
+    <p id="info"></p>
+  </body>
+  <script src="./renderer.js"></script>
+</html>
+```
+
+After following the above steps, your app should look something like this:
+
+![Electron app showing This app is using Chrome (v102.0.5005.63), Node.js (v16.14.2), and Electron (v19.0.3)](../images/preload-example.png)
+
+And the code should look like this:
+
+```fiddle docs/fiddles/tutorial-preload
+
+```
+
+## Communicating between processes
+
+As we have mentioned above, Electron's main and renderer process have distinct responsibilities
+and are not interchangeable. This means it is not possible to access the Node.js APIs directly
+from the renderer process, nor the HTML Document Object Model (DOM) from the main process.
+
+The solution for this problem is to use Electron's `ipcMain` and `ipcRenderer` modules for
+inter-process communication (IPC). To send a message from your web page to the main process,
+you can set up a main process handler with `ipcMain.handle` and
+then expose a function that calls `ipcRenderer.invoke` to trigger the handler in your preload script.
+
+To illustrate, we will add a global function to the renderer called `ping()`
+that will return a string from the main process.
+
+First, set up the `invoke` call in your preload script:
+
+```js {1,7} title="preload.js"
+const { contextBridge, ipcRenderer } = require('electron')
+
+contextBridge.exposeInMainWorld('versions', {
+  node: () => process.versions.node,
+  chrome: () => process.versions.chrome,
+  electron: () => process.versions.electron,
+  ping: () => ipcRenderer.invoke('ping'),
+  // we can also expose variables, not just functions
+})
+```
+
+:::caution IPC security
+
+Notice how we wrap the `ipcRenderer.invoke('ping')` call in a helper function rather
+than expose the `ipcRenderer` module directly via context bridge. You **never** want to
+directly expose the entire `ipcRenderer` module via preload. This would give your renderer
+the ability to send arbitrary IPC messages to the main process, which becomes a powerful
+attack vector for malicious code.
+
+:::
+
+Then, set up your `handle` listener in the main process. We do this _before_
+loading the HTML file so that the handler is guaranteed to be ready before
+you send out the `invoke` call from the renderer.
+
+```js {1,11} title="main.js"
+const { ipcMain } = require('electron')
+
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+    webPreferences: {
+      preload: path.join(__dirname, 'preload.js'),
+    },
+  })
+  ipcMain.handle('ping', () => 'pong')
+  win.loadFile('index.html')
+}
+```
+
+Once you have the sender and receiver set up, you can now send messages from the renderer
+to the main process through the `'ping'` channel you just defined.
+
+```js title='renderer.js'
+const func = async () => {
+  const response = await window.versions.ping()
+  console.log(response) // prints out 'pong'
+}
+
+func()
+```
+
+:::info
+
+For more in-depth explanations on using the `ipcRenderer` and `ipcMain` modules,
+check out the full [Inter-Process Communication][ipc] guide.
+
+:::
+
+## Summary
+
+A preload script contains code that runs before your web page is loaded into the browser
+window. It has access to both DOM APIs and Node.js environment, and is often used to
+expose privileged APIs to the renderer via the `contextBridge` API.
+
+Because the main and renderer processes have very different responsibilities, Electron
+apps often use the preload script to set up inter-process communication (IPC) interfaces
+to pass arbitrary messages between the two kinds of processes.
+
+In the next part of the tutorial, we will be showing you resources on adding more
+functionality to your app, then teaching you distributing your app to users.

+
+## Adding application complexity
+
+If you have been following along, you should have a functional Electron application
+with a static user interface. From this starting point, you can generally progress
+in developing your app in two broad directions:
+
+1. Adding complexity to your renderer process' web app code
+1. Deeper integrations with the operating system and Node.js
+
+It is important to understand the distinction between these two broad concepts. For the
+first point, Electron-specific resources are not necessary. Building a pretty to-do
+list in Electron is just pointing your Electron BrowserWindow to a pretty
+to-do list web app. Ultimately, you are building your renderer's UI using the same tools
+(HTML, CSS, JavaScript) that you would on the web. Therefore, Electron's docs will
+not go in-depth on how to use standard web tools.
+
+On the other hand, Electron also provides a rich set of tools that allow
+you to integrate with the desktop environment, from creating tray icons to adding
+global shortcuts to displaying native menus. It also gives you all the power of a
+Node.js environment in the main process. This set of capabilities separates
+Electron applications from running a website in a browser tab, and are the
+focus of Electron's documentation.
+
+## How-to examples
+
+Electron's documentation has many tutorials to help you with more advanced topics
+and deeper operating system integrations. To get started, check out the
+[How-To Examples][how-to] doc.

+:::
+
+## Learning goals
+
+In this part of the tutorial, we'll be going over the basics of packaging and distributing
+your app with [Electron Forge].
+
+## Using Electron Forge
+
+Electron does not have any tooling for packaging and distribution bundled into its core
+modules. Once you have a working Electron app in dev mode, you need to use
+additional tooling to create a packaged app you can distribute to your users (also known
+as a **distributable**). Distributables can be either installers (e.g. MSI on Windows) or
+portable executable files (e.g. `.app` on macOS).
+
+Electron Forge is an all-in-one tool that handles the packaging and distribution of Electron
+apps. Under the hood, it combines a lot of existing Electron tools (e.g. [`electron-packager`],
+[`@electron/osx-sign`], [`electron-winstaller`], etc.) into a single interface so you do not
+have to worry about wiring them all together.
+
+### Importing your project into Forge
+
+You can install Electron Forge's CLI in your project's `devDependencies` and import your
+existing project with a handy conversion script.
+
+```sh npm2yarn
+npm install --save-dev @electron-forge/cli
+npx electron-forge import
+```
+
+Once the conversion script is done, Forge should have added a few scripts
+to your `package.json` file.
+
+```json title='package.json'
+  //...
+  "scripts": {
+    "start": "electron-forge start",
+    "package": "electron-forge package",
+    "make": "electron-forge make"
+  },
+  //...
+```
+
+:::info CLI documentation
+
+For more information on `make` and other Forge APIs, check out
+the [Electron Forge CLI documentation].
+
+:::
+
+You should also notice that your package.json now has a few more packages installed
+under your `devDependencies`, and contains an added `config.forge` field with an array
+of makers configured. **Makers** are Forge plugins that create distributables from
+your source code. You should see multiple makers in the pre-populated configuration,
+one for each target platform.
+
+### Creating a distributable
+
+To create a distributable, use your project's new `make` script, which runs the
+`electron-forge make` command.
+
+```sh npm2yarn
+npm run make
+```
+
+This `make` command contains two steps:
+
+1. It will first run `electron-forge package` under the hood, which bundles your app
+   code together with the Electron binary. The packaged code is generated into a folder.
+1. It will then use this packaged app folder to create a separate distributable for each
+   configured maker.
+
+After the script runs, you should see an `out` folder containing both the distributable
+and a folder containing the packaged application code.
+
+```plain title='macOS output example'
+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
+```
+
+The distributable in the `out/make` folder should be ready to launch! You have now
+created your first bundled Electron application.
+
+:::tip Distributable formats
+
+Electron Forge can be configured to create distributables in different OS-specific formats
+(e.g. DMG, deb, MSI, etc.). See Forge's [Makers] documentation for all configuration options.
+
+:::
+
+:::note Packaging without Electron Forge
+
+If you want to manually package your code, or if you're just interested understanding the
+mechanics behind packaging an Electron app, check out the full [Application Packaging]
+documentation.
+
+:::
+
+## Important: signing your code
+
+In order to distribute desktop applications to end users, we _highly recommended_ for you
+to **code sign** your Electron app. Code signing is an important part of shipping
+desktop applications, and is mandatory for the auto-update step in the final part
+of the tutorial.
+
+Code signing is a security technology that you use to certify that a desktop app was
+created by a known source. Windows and macOS have their own OS-specific code signing
+systems that will make it difficult for users to download or launch unsigned applications.
+
+If you already have code signing certificates for Windows and macOS, you can set your
+credentials in your Forge configuration. Otherwise, please refer to the full
+[Code Signing] documentation to learn how to purchase a certificate and for more information
+on the desktop app code signing process.
+
+On macOS, code signing is done at the app packaging level. On Windows, distributable installers
+are signed instead.

+## Summary
+
+Electron applications need to be packaged to be distributed to users. In this tutorial,
+you imported your app into Electron Forge and configured it to package your app and
+generate installers.
+
+In order for your application to be trusted by the user's system, you need to digitally
+certify that the distributable is authentic and untampered by code signing it. Your app
+can be signed through Forge once you configure it to use your code signing certificate
+information.

+
+## Learning goals
+
+If you've been following along, this is the last step of the tutorial! In this part,
+you will publish your app to GitHub releases and integrate automatic updates
+into your app code.
+
+## Using update.electronjs.org
+
+The Electron maintainers provide a free auto-updating service for open-source apps
+at https://update.electronjs.org. Its requirements are:
+
+- Your app runs on macOS or Windows
+- Your app has a public GitHub repository
+- Builds are published to [GitHub releases]
+- Builds are [code signed][code-signed]
+
+At this point, we'll assume that you have already pushed all your
+code to a public GitHub repository.
+
+:::info Alternative update services
+
+If you're using an alternate repository host (e.g. GitLab or Bitbucket) or if
+you need to keep your code repository private, please refer to our
+[step-by-step guide][update-server] on hosting your own Electron update server.
+
+:::
+
+## Publishing a GitHub release
+
+Electron Forge has [Publisher] plugins that can automate the distribution
+of your packaged application to various sources. In this tutorial, we will
+be using the GitHub Publisher, which will allow us to publish
+our code to GitHub releases.
+
+### Generating a personal access token
+
+Forge cannot publish to any repository on GitHub without permission. You
+need to pass in an authenticated token that gives Forge access to
+your GitHub releases. The easiest way to do this is to
+[create a new personal access token (PAT)][new-pat]
+with the `public_repo` scope, which gives write access to your public repositories.
+**Make sure to keep this token a secret.**
+
+### Setting up the GitHub Publisher
+
+#### Installing the module
+
+Forge's [GitHub Publisher] is a plugin that
+needs to be installed in your project's `devDependencies`:
+
+```sh npm2yarn
+npm install --save-dev @electron-forge/publisher-github
+```
+
+#### Configuring the publisher in Forge
+
+Once you have it installed, you need to set it up in your Forge
+configuration. A full list of options is documented in the Forge's
+[`PublisherGitHubConfig`] API docs.
+
+```json title='package.json' {6-16}
+{
+  //...
+  "config": {
+    "forge": {
+      "publishers": [
+        {
+          "name": "@electron-forge/publisher-github",
+          "config": {
+            "repository": {
+              "owner": "github-user-name",
+              "name": "github-repo-name"
+            },
+            "prerelease": false,
+            "draft": true
+          }
+        }
+      ]
+    }
+  }
+  //...
+}
+```
+
+:::tip Drafting releases before publishing
+
+Notice that you have configured Forge to publish your release as a draft.
+This will allow you to see the release with its generated artifacts
+without actually publishing it to your end users. You can manually
+publish your releases via GitHub after writing release notes and
+double-checking that your distributables work.
+
+:::
+
+#### Setting up your authentication token
+
+You also need to make the Publisher aware of your authentication token.
+By default, it will use the value stored in the `GITHUB_TOKEN` environment
+variable.
+
+### Running the publish command
+
+Add Forge's [publish command] to your npm scripts.
+
+```json {6} title='package.json'
+  //...
+  "scripts": {
+    "start": "electron-forge start",
+    "package": "electron-forge package",
+    "make": "electron-forge make",
+    "publish": "electron-forge publish"
+  },
+  //...
+```
+
+This command will run your configured makers and publish the output distributables to a new
+GitHub release.
+
+```sh npm2yarn
+npm run publish
+```
+
+By default, this will only publish a single distributable for your host operating system and
+architecture. You can publish for different architectures by passing in the `--arch` flag to your
+Forge commands.
+
+The name of this release will correspond to the `version` field in your project's package.json file.
+
+:::tip Tagging releases
+
+Optionally, you can also [tag your releases in Git][git-tag] so that your
+release is associated with a labeled point in your code history. npm comes
+with a handy [`npm version`](https://docs.npmjs.com/cli/v8/commands/npm-version)
+command that can handle the version bumping and tagging for you.
+
+:::
+
+#### Bonus: Publishing in GitHub Actions
+
+Publishing locally can be painful, especially because you can only create distributables
+for your host operating system (i.e. you can't publish a Window `.exe` file from macOS).
+
+A solution for this would be to publish your app via automation workflows
+such as [GitHub Actions], which can run tasks in the
+cloud on Ubuntu, macOS, and Windows. This is the exact approach taken by [Electron Fiddle].
+You can refer to Fiddle's [Build and Release pipeline][fiddle-build]
+and [Forge configuration][fiddle-forge-config]
+for more details.
+
+## Instrumenting your updater code
+
+Now that we have a functional release system via GitHub releases, we now need to tell our
+Electron app to download an update whenever a new release is out. Electron apps do this
+via the [autoUpdater] module, which reads from an update server feed to check if a new version
+is available for download.
+
+The update.electronjs.org service provides an updater-compatible feed. For example, Electron
+Fiddle v0.28.0 will check the endpoint at https://update.electronjs.org/electron/fiddle/darwin/v0.28.0
+to see if a newer GitHub release is available.
+
+After your release is published to GitHub, the update.electronjs.org service should work
+for your application. The only step left is to configure the feed with the autoUpdater module.
+
+To make this process easier, the Electron team maintains the [`update-electron-app`] module,
+which sets up the autoUpdater boilerplate for update.electronjs.org in one function
+call — no configuration required. This module will search for the update.electronjs.org
+feed that matches your project's package.json `"repository"` field.
+
+First, install the module as a runtime dependency.
+
+```sh npm2yarn
+npm install update-electron-app
+```
+
+Then, import the module and call it immediately in the main process.
+
+```js title='main.js'
+require('update-electron-app')()
+```
+
+And that is all it takes! Once your application is packaged, it will update itself for each new
+GitHub release that you publish.
+
+## Summary
+
+In this tutorial, we configured Electron Forge's GitHub Publisher to upload your app's
+distributables to GitHub releases. Since distributables cannot always be generated
+between platforms, we recommend setting up your building and publishing flow
+in a Continuous Integration pipeline if you do not have access to machines.
+
+Electron applications can self-update by pointing the autoUpdater module to an update server feed.
+update.electronjs.org is a free update server provided by Electron for open-source applications
+published on GitHub releases. Configuring your Electron app to use this service is as easy as
+installing and importing the `update-electron-app` module.
+
+If your application is not eligible for update.electronjs.org, you should instead deploy your
+own update server and configure the autoUpdater module yourself.

patches/chromium/disable_compositor_recycling.patch

@@ -6,19 +6,19 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.
