# Notifications
|
|
|
|
|
|
-## Overview
|
|
|
+Each operating system has its own mechanism to display notifications to users. Electron's notification
|
|
|
+APIs are cross-platform, but are different for each process type.
|
|
|
|
|
|
-All three operating systems provide means for applications to send
|
|
|
-notifications to the user. The technique of showing notifications is different
|
|
|
-for the Main and Renderer processes.
|
|
|
+If you want to use a renderer process API in the main process or vice-versa, consider using
|
|
|
+[inter-process communication](./ipc.md).
|
|
|
|
|
|
-For the Renderer process, 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.
|
|
|
+## Usage
|
|
|
|
|
|
-To show notifications in the Main process, you need to use the
|
|
|
-[Notification](../api/notification.md) module.
|
|
|
+Below are two examples showing how to display notifications for each process type.
|
|
|
|
|
|
-## Example
|
|
|
+### Show notifications in the main process
|
|
|
|
|
|
-### Show notifications in the Renderer process
|
|
|
+Main process notifications are displayed using Electron's [Notification module](../api/notification.md).
|
|
|
+Notification objects created using this module do not appear unless their `show()` instance
|
|
|
+method is called.
|
|
|
|
|
|
-Starting with a working application from the
|
|
|
-[Quick Start Guide](quick-start.md), add the following line to the
|
|
|
-`index.html` file before the closing `</body>` tag:
|
|
|
+```js title='Main Process'
|
|
|
+const { Notification } = require("electron");
|
|
|
|
|
|
-```html
|
|
|
-<script src="renderer.js"></script>
|
|
|
-```
|
|
|
-
|
|
|
-...and add the `renderer.js` file:
|
|
|
-
|
|
|
-```javascript fiddle='docs/fiddles/features/notifications/renderer'
|
|
|
-const NOTIFICATION_TITLE = 'Title'
|
|
|
-const NOTIFICATION_BODY = 'Notification from the Renderer process. Click to log to console.'
|
|
|
-const CLICK_MESSAGE = 'Notification clicked'
|
|
|
+const NOTIFICATION_TITLE = "Basic Notification";
|
|
|
+const NOTIFICATION_BODY = "Notification from the Main process";
|
|
|
|
|
|
-new Notification(NOTIFICATION_TITLE, { body: NOTIFICATION_BODY })
|
|
|
- .onclick = () => console.log(CLICK_MESSAGE)
|
|
|
+new Notification({
|
|
|
+ title: NOTIFICATION_TITLE,
|
|
|
+ body: NOTIFICATION_BODY,
|
|
|
+}).show();
|
|
|
```
|
|
|
|
|
|
-After launching the Electron application, you should see the notification:

|
|
|
+Here's a full example that you can open with Electron Fiddle:
|
|
|
|
|
|
-Additionally, if you click on the notification, the DOM will update to show "Notification clicked!".
|
|

|
|
|
+const { Notification } = require("electron");

|
|
|
+const NOTIFICATION_TITLE = "Basic Notification";
|
|
|
+const NOTIFICATION_BODY = "Notification from the Main process";
|
|
|
|
|
|
-Starting with a working application from the
|
|

|
|
|

|
|
|

|

+ body: NOTIFICATION_BODY,

|
|
|
|
-const NOTIFICATION_TITLE = 'Basic Notification'
|
|
|
-const NOTIFICATION_BODY = 'Notification from the Main process'
|
|
|
+Notifications can be displayed directly from the renderer process with the
|
|
|
+[web Notifications API](https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API/Using_the_Notifications_API).
|
|

|
|
|
+## Platform considerations
|
|
|
|
|
|
While code and user experience across operating systems are similar, there
|
|
|
are subtle differences.
|
|
|
|
|
|
### Windows
|
|
|
|
|
|
-* On Windows 10, a shortcut to your app with an
|
|
|
-[Application User Model ID][app-user-model-id] must be installed to the
|
|
|
-Start Menu. This can be overkill during development, so adding
|
|
|
-`node_modules\electron\dist\electron.exe` to your Start Menu also does the
|
|
|
-trick. Navigate to the file in Explorer, right-click and 'Pin to Start Menu'.
|
|
|
-You will then need to add the line `app.setAppUserModelId(process.execPath)` to
|
|
|
-your main process to see notifications.
|
|
|
+For notifications on Windows, your Electron app needs to have a Start Menu shortcut with an
|
|
|
+[AppUserModelID][app-user-model-id] and a corresponding [ToastActivatorCLSID][toast-activator-clsid].
|
|
|
+
|
|
|
+Electron attempts to automate the work around the AppUserModelID and ToastActivatorCLSID. When
|
|
|
+Electron is used together with Squirrel.Windows (e.g. if you're using electron-winstaller),
|
|
|
+[shortcuts will automatically be set correctly][squirrel-events].
