## Notifications (Windows, Linux, macOS)
|
||||
|
||||
All three operating systems provide means for applications to send notifications
|
||||
to the user. Electron conveniently allows developers to send notifications with
|
||||
the [HTML5 Notification API](https://notifications.spec.whatwg.org/), using
|
||||
the currently running operating system's native notification APIs to display it.
|
||||
|
||||
**Note:** Since this is an HTML5 API it is only available in the renderer process.
|
||||
|
||||
```javascript
|
||||
let myNotification = new Notification('Title', {
|
||||
body: 'Lorem Ipsum Dolor Sit Amet'
|
||||
})
|
||||
|
||||
myNotification.onclick = () => {
|
||||
console.log('Notification clicked')
|
||||
}
|
||||
```
|
||||
|
||||
While code and user experience across operating systems are similar, there
|
||||
are fine differences.
|
||||
|
||||
### Windows
|
||||
|
||||
* On Windows 10, notifications "just work".
|
||||
* On Windows 8.1 and Windows 8, a shortcut to your app, with a [Application User
|
||||
Model ID][app-user-model-id], must be installed to the Start screen. Note,
|
||||
however, that it does not need to be pinned to the Start screen.
|
||||
* On Windows 7, notifications are not supported. You can however send
|
||||
"balloon notifications" using the [Tray API][tray-balloon].
|
||||
|
||||
Furthermore, the maximum length for the notification body is 250 characters,
|
||||
with the Windows team recommending that notifications should be kept to 200
|
||||
characters.
|
||||
|
||||
### Linux
|
||||
|
||||
Notifications are sent using `libnotify`, it can show notifications on any
|
||||
desktop environment that follows [Desktop Notifications
|
||||
Specification][notification-spec], including Cinnamon, Enlightenment, Unity,
|
||||
GNOME, KDE.
|
||||
|
||||
### macOS
|
||||
|
||||
Notifications are straight-forward on macOS, you should however be aware of
|
||||
[Apple's Human Interface guidelines regarding notifications](https://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/OSXHIGuidelines/NotificationCenter.html).
|
||||
|
||||
Note that notifications are limited to 256 bytes in size - and will be truncated
|
||||
if you exceed that limit.
|
||||

# Notifications (Windows, Linux, macOS)
|
||||
|
||||
All three operating systems provide means for applications to send notifications
|
||||
to the user. Electron conveniently allows developers to send notifications with
|
||||
the [HTML5 Notification API](https://notifications.spec.whatwg.org/), using
|

|
||||
|
||||
**Note:** Since this is an HTML5 API it is only available in the renderer process.
|
||||

|
||||

|
||||
body: 'Lorem Ipsum Dolor Sit Amet'
|
||||
})
|
||||
|
||||
myNotification.onclick = () => {
|
||||
console.log('Notification clicked')
|
||||
}
|
||||
```
|
||||
|
||||
While code and user experience across operating systems are similar, there
|
||||
are fine differences.
|
||||
|
||||
## Windows
|
||||
|
||||
* On Windows 10, notifications "just work".
|
||||
* On Windows 8.1 and Windows 8, a shortcut to your app, with a [Application User
|
||||
Model ID][app-user-model-id], must be installed to the Start screen. Note,
|
||||
however, that it does not need to be pinned to the Start screen.
|
||||
* On Windows 7, notifications are not supported. You can however send
|
||||
"balloon notifications" using the [Tray API][tray-balloon].
|
||||
|
||||
Furthermore, in Windows 8, the maximum length for the notification body is 250
|
||||
characters, with the Windows team recommending that notifications should be kept
|
||||
to 200 characters. That said, that limitation has been removed in Windows 10, with
|
||||
the Windows team asking developers to be reasonable. Attempting to send gigantic
|
||||
amounts of text to the API (thousands of characters) might result in instability.
|
||||
|
||||
### Advanced Notifications
|
||||
|
||||
Later versions of Windows allow for advanced notifications, with custom templates,
|
||||
images, and other flexible elements. To send those notifications (from either the
|
||||
main process or the renderer process), use the userland module
|
||||
[electron-windows-notifications](https://github.com/felixrieseberg/electron-windows-notifications),
|
||||
which uses native Node addons to send `ToastNotification` and `TileNotification` objects.
|
||||
|
||||
While notifications including buttons work with just `electron-windows-notifications`,
|
||||
handling replies requires the use of [`electron-windows-interactive-notifications`](https://github.com/felixrieseberg/electron-windows-interactive-notifications), which
|
||||
helps with registering the required COM components and calling your Electron app with
|
||||
the entered user data.
|
||||
|
||||
### Quiet Hours / Presentation Mode
|
||||
|
||||
To detect whether or not you're allowed to send a notification, use the userland module
|
||||
[electron-notification-state](https://github.com/felixrieseberg/electron-notification-state).
|
||||
|
||||
This allows you to determine ahead of time whether or not Windows will silently throw
|
||||
the notification away.
|
||||
|
||||
## macOS
|
||||
|
||||
Notifications are straight-forward on macOS, you should however be aware of
|
||||
[Apple's Human Interface guidelines regarding notifications](https://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/OSXHIGuidelines/NotificationCenter.html).
|
||||
|
||||
Note that notifications are limited to 256 bytes in size - and will be truncated
|
||||
if you exceed that limit.
|
||||
|
||||
### Advanced Notifications
|
||||
|
||||
Later versions of macOS allow for notifications with an input field, allowing the user
|
||||
to quickly respond to a notification. In order to send notifications with an input field,
|
||||
use the userland module [node-mac-notifier](https://github.com/CharlieHess/node-mac-notifier).
|
||||
|
||||
### Do not disturb / Session State
|
||||
|
||||
To detect whether or not you're allowed to send a notification, use the userland module
|
||||
[electron-notification-state](https://github.com/felixrieseberg/electron-notification-state).
|
||||
|
||||
This will allow you to detect ahead of time whether or not the notification will be displayed.
|
||||
|
||||
## Linux
|
||||
|
||||
Notifications are sent using `libnotify`, it can show notifications on any
|
||||
desktop environment that follows [Desktop Notifications
|
||||
