See publish configuration for information on how to configure your local or CI environment for automated deployments.

Simplified auto-update is supported on Windows if you use the default NSIS target, but is not supported for Squirrel.Windows.

Differences between electron-updater and built-in autoUpdater

• It doesn't require a dedicated release server.
• Code signature validation not only on macOS, but also on Windows.
• electron-builder produces and publishes all required metadata files and artifacts.
• Download progress supported on all platforms.
• Staged rollouts supported on all platforms.
• Actually, built-in autoUpdater is used inside on macOS.
• Different providers supported out of the box (GitHub Releases, Amazon S3, DigitalOcean Spaces, Bintray and generic HTTP(s) server).
• You need only 2 lines of code to make it work.

Quick Setup Guide

1. Install electron-updater as an app dependency.

2. Configure publish.

3. Use autoUpdater from electron-updater instead of electron:

   `js import { autoUpdater } from "electron-updater" `

   Or if you don't use ES6: const autoUpdater = require("electron-updater").autoUpdater

4. Call autoUpdater.checkForUpdatesAndNotify(). Or, if you need custom behaviour, implement electron-updater events, check examples below.

NOTICE:

1. Do not call setFeedURL. electron-builder automatically creates app-update.yml file for you on build in the resources (this file is internal, you don't need to be aware of it).
2. zip target for macOS is required for Squirrel.Mac, whereas latest-mac.yml cannot be created, which causes autoUpdater error. Default target for macOS dmg+zip, you don't need to explicitly specify target.

Examples

• Example in Typescript using system notifications.
• A complete example showing how to use.
• An encapsulated manual update via menu.

Debugging

You don't need to listen all events to understand what's wrong. Just set logger. electron-log is recommended (it is an additional dependency that you can install if needed).

autoUpdater.logger = require("electron-log")
autoUpdater.logger.transports.file.level = "info"

Staged Rollouts

Staged rollouts allow you to distribute the latest version of your app to a subset of users that you can increase over time, similar to rollouts on platforms like Google Play.

Staged rollouts are controlled by manually editing your latest.yml / latest-mac.yml (channel update info file).

version: 1.1.0
path: TestApp Setup 1.1.0.exe
sha512: Dj51I0q8aPQ3ioaz9LMqGYujAYRbDNblAQbodDRXAMxmY6hsHqEl3F6SvhfJj5oPhcqdX1ldsgEvfMNXGUXBIw==
stagingPercentage: 10

Update will be shipped to 10% of userbase.

If you want to pull a staged release because it hasn't gone well, you must increment the version number higher than your broken release. Because some of your users will be on the broken 1.0.1, releasing a new 1.0.1 would result in them staying on a broken version.

File Generated and Uploaded in Addition

latest.yml (or latest-mac.yml for macOS, or latest-linux.yml for Linux) will be generated and uploaded for all providers except bintray (because not required, bintray doesn't use latest.yml).

Private GitHub Update Repo

You can use a private repository for updates with electron-updater by setting the GH_TOKEN environment variable (on user machine) and private option. If GH_TOKEN is set, electron-updater will use the GitHub API for updates allowing private repositories to work.

Only for very special cases — not intended and not suitable for all users.

Note: The GitHub API currently has a rate limit of 5000 requests per user per hour. An update check uses up to 3 requests per check.

Events

The autoUpdater object emits the following events:

Event: error

• error Error

Emitted when there is an error while updating.

Event: checking-for-update

Emitted when checking if an update has started.

Event: update-available

• infoUpdateInfo (for generic and github providers) | VersionInfo (for Bintray provider)

Emitted when there is an available update. The update is downloaded automatically if autoDownload is true.

Event: update-not-available

Emitted when there is no available update.

• infoUpdateInfo (for generic and github providers) | VersionInfo (for Bintray provider)

Event: download-progress

• progress ProgressInfo
  • bytesPerSecond
  • percent
  • total
  • transferred

Emitted on progress. Only supported over Windows build, since Squirrel.Macdoes not provide this data.

Event: update-downloaded

• infoUpdateInfo — for generic and github providers. VersionInfo for Bintray provider.

AppUpdater ⇐ EventEmitter

Kind: class of electron-updater<br/> Extends: EventEmitter
Properties

• autoDownload = true Boolean - Whether to automatically download an update when it is found.

• allowPrerelease = false Boolean - GitHub provider only. Whether to allow update to pre-release versions. Defaults to true if application version contains prerelease components (e.g. 0.12.1-alpha.1, here alpha is a prerelease component), otherwise false.

  If true, downgrade will be allowed (allowDowngrade will be set to true).

• fullChangelog = false Boolean - GitHub provider only. Get all release notes (from current version to latest), not just the latest.
• allowDowngrade = false Boolean - Whether to allow version downgrade (when a user from the beta channel wants to go back to the stable channel).
• currentVersion String - The current application version.
• requestHeaders [key: string]: string - The request headers.
• loggerLogger - The logger. You can pass electron-log, winston or another logger with the following interface: { info(), warn(), error() }. Set it to null if you would like to disable a logging feature.
• signals = new UpdaterSignal(this)UpdaterSignal - For type safety you can use signals, e.g. autoUpdater.signals.updateDownloaded(() => {}) instead of autoUpdater.on('update-available', () => {})
• configOnDisk = new Lazy<any>(() => this.loadUpdateConfig()) Lazy<any>

Methods

• .AppUpdater ⇐ EventEmitter

  • .downloadUpdate(cancellationToken) ⇒ Promise<any>
  • .getFeedURL() ⇒ undefined | null | String
  • .setFeedURL(options)
  • .quitAndInstall(isSilent, isForceRunAfter)

appUpdater.checkForUpdates() ⇒ Promise<UpdateCheckResult>

Asks the server whether there is an update.

appUpdater.checkForUpdatesAndNotify() ⇒ Promise< | UpdateCheckResult>

appUpdater.downloadUpdate(cancellationToken) ⇒ Promise<any>

Start downloading update manually. You can use this method if autoDownload option is set to false.

Returns: Promise<any> - Path to downloaded file.

• cancellationToken CancellationToken

appUpdater.getFeedURL() ⇒ undefined | null | String

appUpdater.setFeedURL(options)

Configure update provider. If value is string, GenericServerOptions will be set with value as url.

• options PublishConfiguration | String | GithubOptions | S3Options | SpacesOptions | GenericServerOptions | BintrayOptions - If you want to override configuration in the app-update.yml.

appUpdater.quitAndInstall(isSilent, isForceRunAfter)

Restarts the app and installs the update after it has been downloaded. It should only be called after update-downloaded has been emitted.

Note:autoUpdater.quitAndInstall() will close all application windows first and only emit before-quit event on app after that. This is different from the normal quit event sequence.

• isSilent Boolean - windows-only Runs the installer in silent mode.
• isForceRunAfter Boolean - windows-only Run the app after finish even on silent install.
