-
-The `pushNotification` module emits the following events:
-
-#### Event: 'received-apns-notification' _macOS_
-
-Returns:
-
-* `userInfo` Record<String, any>
-
-Emitted when the app receives a remote notification while running.
-See: https://developer.apple.com/documentation/appkit/nsapplicationdelegate/1428430-application?language=objc
-
-## Methods
-
-The `pushNotification` module has the following methods:
-
-### `pushNotifications.registerForAPNSNotifications()` _macOS_
-
-Returns `Promise<string>`
-
-Registers the app with Apple Push Notification service (APNS) to receive [Badge, Sound, and Alert](https://developer.apple.com/documentation/appkit/sremotenotificationtype?language=objc) notifications. If registration is successful, the promise will be resolved with the APNS device token. Otherwise, the promise will be rejected with an error message.
-See: https://developer.apple.com/documentation/appkit/nsapplication/1428476-registerforremotenotificationtyp?language=objc
-
-### `pushNotifications.unregisterForAPNSNotifications()` _macOS_
-
-Unregisters the app from notifications received from APNS.

+title: ASAR Archives
+description: What is ASAR archive and how does it affect the application.
+slug: asar-archives
+hide_title: false
+---
+
+After creating an [application distribution](application-distribution.md), the
+app's source code are usually bundled into an [ASAR
+archive](https://github.com/electron/asar), which is a simple extensive archive
+format designed for Electron apps. By bundling the app we can mitigate issues
+around long path names on Windows, speed up `require` and conceal your source
+code from cursory inspection.
+
+The bundled app runs in a virtual file system and most APIs would just work
+normally, but for some cases you might want to work on ASAR archives explicitly
+due to a few caveats.
+
+## Using ASAR Archives
+
+In Electron there are two sets of APIs: Node APIs provided by Node.js and Web
+APIs provided by Chromium. Both APIs support reading files from ASAR archives.
+
+### Node API
+
+With special patches in Electron, Node APIs like `fs.readFile` and `require`
+treat ASAR archives as virtual directories, and the files in it as normal
+files in the filesystem.
+
+For example, suppose we have an `example.asar` archive under `/path/to`:
+
+```sh
+$ asar list /path/to/example.asar
+/app.js
+/file.txt
+/dir/module.js
+/static/index.html
+/static/main.css
+/static/jquery.min.js
+```
+
+Read a file in the ASAR archive:
+
+```javascript
+const fs = require('fs')
+fs.readFileSync('/path/to/example.asar/file.txt')
+```
+
+List all files under the root of the archive:
+
+```javascript
+const fs = require('fs')
+fs.readdirSync('/path/to/example.asar')
+```
+
+Use a module from the archive:
+
+```javascript
+require('./path/to/example.asar/dir/module.js')
+```
+
+You can also display a web page in an ASAR archive with `BrowserWindow`:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow()
+
+win.loadURL('file:///path/to/example.asar/static/index.html')
+```
+
+### Web API
+
+In a web page, files in an archive can be requested with the `file:` protocol.
+Like the Node API, ASAR archives are treated as directories.
+
+For example, to get a file with `$.get`:
+
+```html
+<script>
+let $ = require('./jquery.min.js')
+$.get('file:///path/to/example.asar/file.txt', (data) => {
+  console.log(data)
+})
+</script>
+```
+
+### Treating an ASAR archive as a Normal File
+
+For some cases like verifying the ASAR archive's checksum, we need to read the
+content of an ASAR archive as a file. For this purpose you can use the built-in
+`original-fs` module which provides original `fs` APIs without `asar` support:
+
+```javascript
+const originalFs = require('original-fs')
+originalFs.readFileSync('/path/to/example.asar')
+```
+
+You can also set `process.noAsar` to `true` to disable the support for `asar` in
+the `fs` module:
+
+```javascript
+const fs = require('fs')
+process.noAsar = true
+fs.readFileSync('/path/to/example.asar')
+```
+
+## Limitations of the Node API
+
+Even though we tried hard to make ASAR archives in the Node API work like
+directories as much as possible, there are still limitations due to the
+low-level nature of the Node API.
+
+### Archives Are Read-only
+
+The archives can not be modified so all Node APIs that can modify files will not
+work with ASAR archives.
+
+### Working Directory Can Not Be Set to Directories in Archive
+
+Though ASAR archives are treated as directories, there are no actual
+directories in the filesystem, so you can never set the working directory to
+directories in ASAR archives. Passing them as the `cwd` option of some APIs
+will also cause errors.
+
+### Extra Unpacking on Some APIs
+
+Most `fs` APIs can read a file or get a file's information from ASAR archives
+without unpacking, but for some APIs that rely on passing the real file path to
+underlying system calls, Electron will extract the needed file into a
+temporary file and pass the path of the temporary file to the APIs to make them
+work. This adds a little overhead for those APIs.
+
+APIs that requires extra unpacking are:
+
+* `child_process.execFile`
+* `child_process.execFileSync`
+* `fs.open`
+* `fs.openSync`
+* `process.dlopen` - Used by `require` on native modules
+
+### Fake Stat Information of `fs.stat`
+
+The `Stats` object returned by `fs.stat` and its friends on files in `asar`
+archives is generated by guessing, because those files do not exist on the
+filesystem. So you should not trust the `Stats` object except for getting file
+size and checking file type.
+
+### Executing Binaries Inside ASAR archive
+
+There are Node APIs that can execute binaries like `child_process.exec`,
+`child_process.spawn` and `child_process.execFile`, but only `execFile` is
+supported to execute binaries inside ASAR archive.
+
+This is because `exec` and `spawn` accept `command` instead of `file` as input,
+and `command`s are executed under shell. There is no reliable way to determine
+whether a command uses a file in asar archive, and even if we do, we can not be
+sure whether we can replace the path in command without side effects.
+
+## Adding Unpacked Files to ASAR archives
+
+As stated above, some Node APIs will unpack the file to the filesystem when
+called. Apart from the performance issues, various anti-virus scanners might
+be triggered by this behavior.
+
+As a workaround, you can leave various files unpacked using the `--unpack` option.
+In the following example, shared libraries of native Node.js modules will not be
+packed:
+
+```sh
+$ asar pack app app.asar --unpack *.node
+```
+
+After running the command, you will notice that a folder named `app.asar.unpacked`
+was created together with the `app.asar` file. It contains the unpacked files
+and should be shipped together with the `app.asar` archive.

+slug: asar-integrity
+hide_title: false
+---
+
+## Platform Support
+
+Currently ASAR integrity checking is only supported on macOS.
+
+## Requirements
+
+### Electron Forge / Electron Packager
+
+If you are using `>= electron-packager@15.4.0` or `>= @electron-forge/core@6.0.0-beta.61` then all these requirements are met for you automatically and you can skip to [Toggling the Fuse](#toggling-the-fuse).
+
+### Other build systems
+
+In order to enable ASAR integrity checking you need to ensure that your `app.asar` file was generated by a version of the `asar` npm package that supports asar integrity.  Support was introduced in version `3.1.0`.
+
+Your must then populate a valid `ElectronAsarIntegrity` dictionary block in your packaged apps `Info.plist`.  An example is included below.
+
+```plist
+<key>ElectronAsarIntegrity</key>
+<dict>
+  <key>Resources/app.asar</key>
+  <dict>
+    <key>algorithm</key>
+    <string>SHA256</string>

+  </dict>
+</dict>
+```
+
+Valid `algorithm` values are currently `SHA256` only.  The `hash` is a hash of the ASAR header using the given algorithm.  The `asar` package exposes a `getRawHeader` method whose result can then be hashed to generate this value.
+
+## Toggling the Fuse
+
+ASAR integrity checking is currently disabled by default and can be enabled by toggling a fuse. See [Electron Fuses](fuses.md) for more information on what Electron Fuses are and how they work.  When enabling this fuse you typically also want to enable the `onlyLoadAppFromAsar` fuse otherwise the validity checking can be bypassed via the Electron app code search path.

+  // E.g. /a/b/Foo.app

@@ -8,6 +8,59 @@ For a subset of Electron functionality it makes sense to disable certain feature
 
 Fuses are the solution to this problem, at a high level they are "magic bits" in the Electron binary that can be flipped when packaging your Electron app to enable / disable certain features / restrictions.  Because they are flipped at package time before you code sign your app the OS becomes responsible for ensuring those bits aren't flipped back via OS level code signing validation (Gatekeeper / App Locker).
 
+## Current Fuses
+
+### `runAsNode`
+
+**Default:** Enabled
+**@electron/fuses:** `FuseV1Options.RunAsNode`
+
+The runAsNode fuse toggles whether the `ELECTRON_RUN_AS_NODE` environment variable is respected or not.  Please note that if this fuse is disabled then `process.fork` in the main process will not function as expected as it depends on this environment variable to function.
+
+### `cookieEncryption`
+
+**Default:** Disabled
+**@electron/fuses:** `FuseV1Options.EnableCookieEncryption`
+
+The cookieEncryption fuse toggles whether the cookie store on disk is encrypted using OS level cryptography keys.  By default the sqlite database that Chromium uses to store cookies stores the values in plaintext.  If you wish to ensure your apps cookies are encrypted in the same way Chrome does then you should enable this fuse.  Please note it is a one-way transition, if you enable this fuse existing unencrypted cookies will be encrypted-on-write but if you then disable the fuse again your cookie store will effectively be corrupt and useless.  Most apps can safely enable this fuse.
+
+### `nodeOptions`
+
+**Default:** Enabled
+**@electron/fuses:** `FuseV1Options.EnableNodeOptionsEnvironmentVariable`
+
+The nodeOptions fuse toggles whether the [`NODE_OPTIONS`](https://nodejs.org/api/cli.html#node_optionsoptions) environment variable is respected or not.  This environment variable can be used to pass all kinds of custom options to the Node.js runtime and isn't typically used by apps in production.  Most apps can safely disable this fuse.
+
+### `nodeCliInspect`
+
+**Default:** Enabled
+**@electron/fuses:** `FuseV1Options.EnableNodeCliInspectArguments`
+
+The nodeCliInspect fuse toggles whether the `--inspect`, `--inspect-brk`, etc. flags are respected or not.  When disabled it also ensures that `SIGUSR1` signal does not initialize the main process inspector.  Most apps can safely disable this fuse.
+
+### `embeddedAsarIntegrityValidation`
+
+**Default:** Disabled
+**@electron/fuses:** `FuseV1Options.EnableEmbeddedAsarIntegrityValidation`
+
+The embeddedAsarIntegrityValidation fuse toggles an experimental feature on macOS that validates the content of the `app.asar` file when it is loaded.  This feature is designed to have a minimal performance impact but may marginally slow down file reads from inside the `app.asar` archive.
+
+For more information on how to use asar integrity validation please read the [Asar Integrity](asar-integrity.md) documentation.
+
+### `onlyLoadAppFromAsar`
+
+**Default:** Disabled
+**@electron/fuses:** `FuseV1Options.OnlyLoadAppFromAsar`
+
+The onlyLoadAppFromAsar fuse changes the search system that Electron uses to locate your app code.  By default Electron will search in the following order `app.asar` -> `app` -> `default_app.asar`.  When this fuse is enabled the search order becomes a single entry `app.asar` thus ensuring that when combined with the `embeddedAsarIntegrityValidation` fuse it is impossible to load non-validated code.
+
+### `loadBrowserProcessSpecificV8Snapshot`
+
+**Default:** Disabled
+**@electron/fuses:** `FuseV1Options.LoadBrowserProcessSpecificV8Snapshot`
+
+The loadBrowserProcessSpecificV8Snapshot fuse changes which V8 snapshot file is used for the browser process.  By default Electron's processes will all use the same V8 snapshot file.  When this fuse is enabled the browser process uses the file called `browser_v8_context_snapshot.bin` for its V8 snapshot. The other processes will use the V8 snapshot file that they normally do.

-displaying untrusted web content. However, even purportedly trusted code may be
-dangerous — there are countless attack vectors that malicious actors can use, from

-# Testing Widevine CDM
-
-In Electron you can use the Widevine CDM library shipped with Chrome browser.
-
-Widevine Content Decryption Modules (CDMs) are how streaming services protect
-content using HTML5 video to web browsers without relying on an NPAPI plugin
-like Flash or Silverlight. Widevine support is an alternative solution for
-streaming services that currently rely on Silverlight for playback of
-DRM-protected video content. It will allow websites to show DRM-protected video
-content in Firefox without the use of NPAPI plugins. The Widevine CDM runs in an
-open-source CDM sandbox providing better user security than NPAPI plugins.
-
-#### Note on VMP
-
-As of [`Electron v1.8.0 (Chrome v59)`](https://electronjs.org/releases#1.8.1),
-the below steps are may only be some of the necessary steps to enable Widevine;
-any app on or after that version intending to use the Widevine CDM may need to
-be signed using a license obtained from [Widevine](https://www.widevine.com/)
-itself.
-
-Per [Widevine](https://www.widevine.com/):
-
-> Chrome 59 (and later) includes support for Verified Media Path (VMP). VMP
-> provides a method to verify the authenticity of a device platform. For browser
-> deployments, this will provide an additional signal to determine if a
-> browser-based implementation is reliable and secure.
->
-> The proxy integration guide has been updated with information about VMP and
-> how to issue licenses.
->
-> Widevine recommends our browser-based integrations (vendors and browser-based
-> applications) add support for VMP.
-
-To enable video playback with this new restriction,
-[castLabs](https://castlabs.com/open-source/downstream/) has created a
-[fork](https://github.com/castlabs/electron-releases) that has implemented the
-necessary changes to enable Widevine to be played in an Electron application if
-one has obtained the necessary licenses from widevine.
-
-## Getting the library
-
-Open `chrome://components/` in Chrome browser, find `Widevine Content Decryption Module`
-and make sure it is up to date, then you can find the library files from the
-application directory.
-
-### On Windows
-
-The library file `widevinecdm.dll` will be under
-`Program Files(x86)/Google/Chrome/Application/CHROME_VERSION/WidevineCdm/_platform_specific/win_(x86|x64)/`
-directory.
-
-### On macOS
-
-The library file `libwidevinecdm.dylib` will be under
-`/Applications/Google Chrome.app/Contents/Versions/CHROME_VERSION/Google Chrome Framework.framework/Versions/A/Libraries/WidevineCdm/_platform_specific/mac_(x86|x64)/`
-directory.
-
-**Note:** Make sure that chrome version used by Electron is greater than or
-equal to the `min_chrome_version` value of Chrome's widevine cdm component.
-The value can be found in `manifest.json` under `WidevineCdm` directory.
-
-## Using the library
-
-After getting the library files, you should pass the path to the file
-with `--widevine-cdm-path` command line switch, and the library's version
-with `--widevine-cdm-version` switch. The command line switches have to be
-passed before the `ready` event of `app` module gets emitted.
-
-Example code:
-
-```javascript
-const { app, BrowserWindow } = require('electron')
-
-// You have to pass the directory that contains widevine library here, it is
-// * `libwidevinecdm.dylib` on macOS,
-// * `widevinecdm.dll` on Windows.
-app.commandLine.appendSwitch('widevine-cdm-path', '/path/to/widevine_library')
-// The version of plugin can be got from `chrome://components` page in Chrome.
-app.commandLine.appendSwitch('widevine-cdm-version', '1.4.8.866')
-
-let win = null
-app.whenReady().then(() => {
-  win = new BrowserWindow()
-  win.show()
-})
-```
-
-## Verifying Widevine CDM support
-
-To verify whether widevine works, you can use following ways:
-
-* Open https://shaka-player-demo.appspot.com/ and load a manifest that uses
-`Widevine`.
-* Open http://www.dash-player.com/demo/drm-test-area/, check whether the page
-says `bitdash uses Widevine in your browser`, then play the video.
