ToastNotification

The constructor for the ToastNotification class accepts an options object with the following properties:

  • string template - The XML template for the notification. You can also call new Template() with few properties to customize your own XML template based on the default. See example: template.js
  • string[] strings - An array of strings to be used in your template. XML escaping is applied to all strings.
  • Date expirationTime - Time after which a toast notification should not be displayed.
  • string group - Group identifier for the notification.
  • string tag - Unique identifier of this notification within the notification group.
  • string appId - appUserModelId of the application for which the notification is sent. If not passed, it will be assumed to be a global property in Electron's main thread.
const appId = 'electron-windows-notifications'
const {ToastNotification} = require('electron-windows-notifications')

let notification = new ToastNotification({
    appId: appId,
    template: `<toast><visual><binding template="ToastText01"><text id="1">%s</text></binding></visual></toast>`,
    strings: ['Hi!']
})

notification.on('activated', () => console.log('Activated!'))
notification.show()

TileNotification

Tile notifications update the app's primary or secondary tiles. They require that the app is running inside the UWP model, which is possible on Windows 10 Anniversary Update and later. For more information, check out electron-windows-store. The constructor for the TileNotification class accepts an options object with the following properties:

  • string template - The XML template for the notification. You can also call new Template() with few properties to customize your own XML template based on the default. See example: template.js
  • string[] strings - An array of strings to be used in your template. XML escaping is applied to all strings.
  • string tag - Unique identifier of this notification within the notification group.
  • string tileId - If set, the given tile will be updated. Otherwise, the app's primary tile will be used.
const appId = 'electron-windows-notifications'
const {ToastNotification} = require('electron-windows-notifications')

let notification = new ToastNotification({
    appId: appId,
    template: `<toast><visual><binding template="ToastText01"><text id="1">%s</text></binding></visual></toast>`,
    strings: ['Hi!']
})

notification.on('activated', () => console.log('Activated!'))
notification.show()

Hints

appUserModelId

The appUserModelId identifies application in Windows. In Electron, you can set it at runtime using the app.setAppUserModelId() method. If you don't pass it, this module will assume that it's a property on Electron's main thread. Unless running inside a UWP container, you probably want to pass it.

Mysterious Failures & XML Escaping

Microsoft follows the XML spec to the letter - and XML has escaping rules you might not be familiar with. If you're adding strings and properties to your template, consider just using the strings property in the constructor - it will automatically properly escape all input.

String replacement

Inside the module, util.format is used. It'll format the template in a printf-like format. The template is expected to hold zero or more placeholders. Each placeholder is replaced with the converted value from its corresponding argument. If the placeholder does not have a corresponding argument, the placeholder is not replaced. Supported placeholders are:

  • %s - String.
  • %d - Number (both integer and float).
  • %j - JSON.
  • %% - single percent sign ('%'). This does not consume an argument.
