# autoUpdater
|
|
|
|
> Enable apps to automatically update themselves.
|
|
|
|
Process: [Main](../glossary.md#main-process)
|
|
|
|
**You can find a detailed guide about how to implement updates into your application [here](../tutorial/updates.md).**
|
|
|
|
## Platform Notices
|
|
|
|
Currently, only macOS and Windows are supported. There is no built-in support
|
|
for auto-updater on Linux, so it is recommended to use the
|
|
distribution's package manager to update your app.
|
|
|
|
In addition, there are some subtle differences on each platform:
|
|
|
|
### macOS
|
|
|
|
On macOS, the `autoUpdater` module is built upon [Squirrel.Mac][squirrel-mac],
|
|
meaning you don't need any special setup to make it work. For server-side
|
|
requirements, you can read [Server Support][server-support]. Note that [App
|
|
Transport Security](https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW35) (ATS) applies to all requests made as part of the
|
|
update process. Apps that need to disable ATS can add the
|
|
`NSAllowsArbitraryLoads` key to their app's plist.
|
|
|
|
**Note:** Your application must be signed for automatic updates on macOS.
|
|
This is a requirement of `Squirrel.Mac`.
|
|
|
|
### Windows
|
|
|
|
On Windows, you have to install your app into a user's machine before you can
|
|
use the `autoUpdater`, so it is recommended that you use the
|
|
[electron-winstaller][installer-lib], [electron-forge][electron-forge-lib] or the [grunt-electron-installer][installer] package to generate a Windows installer.
|
|
|
|
When using [electron-winstaller][installer-lib] or [electron-forge][electron-forge-lib] make sure you do not try to update your app [the first time it runs](https://github.com/electron/windows-installer#handling-squirrel-events) (Also see [this issue for more info](https://github.com/electron/electron/issues/7155)). It's also recommended to use [electron-squirrel-startup](https://github.com/mongodb-js/electron-squirrel-startup) to get desktop shortcuts for your app.
|
|
|
|
The installer generated with Squirrel will create a shortcut icon with an
|
|
[Application User Model ID][app-user-model-id] in the format of
|
|
`com.squirrel.PACKAGE_ID.YOUR_EXE_WITHOUT_DOT_EXE`, examples are
|
|
`com.squirrel.slack.Slack` and `com.squirrel.code.Code`. You have to use the
|
|
same ID for your app with `app.setAppUserModelId` API, otherwise Windows will
|
|
not be able to pin your app properly in task bar.
|
|
|
|
Unlike Squirrel.Mac, Windows can host updates on S3 or any other static file host.
|
|
You can read the documents of [Squirrel.Windows][squirrel-windows] to get more details
|
|
about how Squirrel.Windows works.
|
|
|
|
## Events
|
|
|
|
The `autoUpdater` object emits the following events:
|
|
|
|
### Event: 'error'
|
|
|
|
Returns:
|
|
|
|
* `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'
|
|
|
|
Emitted when there is an available update. The update is downloaded
|
|
automatically.
|
|
|
|
### Event: 'update-not-available'
|
|
|
|
Emitted when there is no available update.
|
|
|
|
### Event: 'update-downloaded'
|
|
|
|
Returns:
|
|
|
|
* `event` Event
|
|
* `releaseNotes` String
|
|
* `releaseName` String
|
|
* `releaseDate` Date
|
|
* `updateURL` String
|
|
|
|
Emitted when an update has been downloaded.
|
|
|
|
On Windows only `releaseName` is available.
|
|
|
|
## Methods
|
|
|
|
The `autoUpdater` object has the following methods:
|
|
|
|
### `autoUpdater.setFeedURL(url[, requestHeaders])`
|
|
|
|
* `url` String
|
|
* `requestHeaders` Object _macOS_ (optional) - HTTP request headers.
|
|
|
|
Sets the `url` and initialize the auto updater.
|
|
|
|
### `autoUpdater.getFeedURL()`
|
|
|
|
Returns `String` - The current update feed URL.
|
|
|
|
### `autoUpdater.checkForUpdates()`
|
|
|
|
Asks the server whether there is an update. You must call `setFeedURL` before
|
|
using this API.
|
|
|
|
### `autoUpdater.quitAndInstall()`
|
|
|
|
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.
