@electron/notarize

What is @electron/notarize?

@electron/notarize is an npm package designed to help developers notarize their Electron applications for macOS. Notarization is a process by which Apple scans your app for malicious content and checks for code-signing issues. This package simplifies the process of submitting your app to Apple's notarization service and retrieving the results.

What are @electron/notarize's main functionalities?

Notarize an Electron App

This feature allows you to notarize your Electron application by providing the app bundle ID, the path to your app, and your Apple ID credentials. The function `notarize` handles the submission to Apple's notarization service.

const { notarize } = require('@electron/notarize');

async function notarizeApp() {
  await notarize({
    appBundleId: 'com.example.app',
    appPath: '/path/to/your/app.app',
    appleId: '[e-mail]',
    appleIdPassword: 'your-apple-id-password'
  });
}

notarizeApp().catch(console.error);

Check Notarization Status

This feature allows you to check the status of a notarization request by providing the request UUID and your Apple ID credentials. The function `checkNotarizationStatus` retrieves the current status of the notarization process.

const { checkNotarizationStatus } = require('@electron/notarize');

async function checkStatus(requestUUID) {
  const status = await checkNotarizationStatus({
    requestUUID,
    appleId: '[e-mail]',
    appleIdPassword: 'your-apple-id-password'
  });
  console.log(status);
}

checkStatus('your-request-uuid').catch(console.error);

Staple Notarization Ticket

This feature allows you to staple the notarization ticket to your Electron application. The function `stapleApp` ensures that the notarization ticket is attached to your app, which is required for distribution.

const { stapleApp } = require('@electron/notarize');

async function staple() {
  await stapleApp({
    appPath: '/path/to/your/app.app'
  });
}

staple().catch(console.error);

Other packages similar to @electron/notarize

electron-osx-sign

electron-osx-sign is a package that provides code-signing capabilities for macOS Electron applications. While it focuses on code-signing, it also offers notarization features. However, @electron/notarize is more specialized and streamlined for the notarization process.

electron-builder

electron-builder is a comprehensive package for building and packaging Electron applications. It includes features for code-signing and notarization, among many other functionalities. While it is more feature-rich, @electron/notarize is more focused and easier to use specifically for notarization tasks.

Installation

# yarn
yarn add @electron/notarize --dev

What is app "notarization"?

From Apple's docs in XCode:

A notarized app is a macOS app that was uploaded to Apple for processing before it was distributed. When you export a notarized app from Xcode, it code signs the app with a Developer ID certificate and staples a ticket from Apple to the app. The ticket confirms that you previously uploaded the app to Apple.

On macOS 10.14 and later, the user can launch notarized apps when Gatekeeper is enabled. When the user first launches a notarized app, Gatekeeper looks for the app’s ticket online. If the user is offline, Gatekeeper looks for the ticket that was stapled to the app.

Apple has made this a hard requirement as of 10.15 (Catalina).

Prerequisites

For notarization, you need the following things:

1. Xcode 10 or later installed on your Mac.
2. An Apple Developer account.
3. An app-specific password for your ADC account’s Apple ID.
4. Your app may need to be signed with hardened-runtime, including the following entitlement:
   1. com.apple.security.cs.allow-jit

If you are using Electron 11 or below, you must add the com.apple.security.cs.allow-unsigned-executable-memory entitlement too. When using version 12+, this entitlement should not be applied as it increases your app's attack surface.

API

Method: notarize(opts): Promise<void>

• options Object
  • tool String - The notarization tool to use, default is legacy. Can be legacy or notarytool. notarytool is substantially (10x) faster.
  • appPath String - The absolute path to your .app file
  • There are different options for each tool: Legacy
    • appBundleId String - The app bundle identifier your Electron app is using. E.g. com.github.electron
    • ascProvider String (optional) - Your Team Short Name.
    • There are two authentication methods available: user name with password:
      • appleId String - The username of your apple developer account
      • appleIdPassword String - The app-specific password (not your Apple ID password).
    • ... or apiKey with apiIssuer:
      • appleApiKey String - Required for JWT authentication. See Note on JWT authentication below.
      • appleApiIssuer String - Issuer ID. Required if appleApiKey is specified.
  • ... or Notary Tool
    • There are three authentication methods available: user name with password:
      • appleId String - The username of your apple developer account
      • appleIdPassword String - The app-specific password (not your Apple ID password).
      • teamId String - The team ID you want to notarize under.
    • ... or apiKey with apiIssuer:
      • appleApiKey String - Required for JWT authentication. See Note on JWT authentication below.
      • appleApiKeyId String - Required for JWT authentication. See Note on JWT authentication below.
      • appleApiIssuer String - Issuer ID. Required if appleApiKey is specified.
    • ... or keychain with keychainProfile:
      • keychain String - The name of the keychain or path to the keychain you stored notarization credentials in.
      • keychainProfile String - The name of the profile you provided when storing notarization credentials.

Safety when using appleIdPassword

1. Never hard code your password into your packaging scripts, use an environment variable at a minimum.
2. It is possible to provide a keychain reference instead of your actual password (assuming that you have already logged into the Application Loader from Xcode). For example:

const password = `@keychain:"Application Loader: ${appleId}"`;

Another option is that you can add a new keychain item using either the Keychain Access app or from the command line using the security utility:

security add-generic-password -a "AC_USERNAME" -w <app_specific_password> -s "AC_PASSWORD"

where AC_USERNAME should be replaced with your Apple ID, and then in your code you can use:

const password = `@keychain:AC_PASSWORD`;

Notes on JWT authentication

You can obtain an API key from Appstore Connect. Create a key with App Manager access. Note down the Issuer ID and download the .p8 file. This file is your API key and comes with the name of AuthKey_<api_key>.p8. This is the string you have to supply when calling notarize.

Based on the ApiKey, altool will look in the following places for that file:

• ./private_keys
• ~/private_keys
• ~/.private_keys
• ~/.appstoreconnect/private_keys

Notes on your Team Short Name

If you are a member of multiple teams or organizations, you have to tell Apple on behalf of which organization you're uploading. To find your team's short name), you can ask iTMSTransporter, which is part of the now deprecated Application Loader as well as the newer Transporter.

With Transporter installed, run:

/Applications/Transporter.app/Contents/itms/bin/iTMSTransporter -m provider -u APPLE_DEV_ACCOUNT -p APP_PASSWORD

Alternatively, with older versions of Xcode, run:

/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter -m provider -u APPLE_DEV_ACCOUNT -p APP_PASSWORD

Example Usage

import { notarize } from '@electron/notarize';

async function packageTask () {
  // Package your app here, and code sign with hardened runtime
  await notarize({
    appBundleId,
    appPath,
    appleId,
    appleIdPassword,
    ascProvider, // This parameter is optional
  });
