Package: @syncfusion/ej2-notifications

Toast Component

Purpose: Displays brief, non-intrusive notifications that auto-dismiss after a configurable timeout. Supports rich content through templates, action buttons, animated entry/exit, precise positioning, and programmatic control via ToastUtility.

Package: @syncfusion/ej2-notifications

Quick Example

import { Toast } from '@syncfusion/ej2-notifications';

let toastObj: Toast = new Toast({
  title: 'Success!',
  content: 'Your changes have been saved.',
  position: { X: 'Right', Y: 'Bottom' },
  timeOut: 4000,
  showCloseButton: true
});
toastObj.appendTo('#toast');
toastObj.show();

Quick Utility Toast (No Component Needed)

import { ToastUtility } from '@syncfusion/ej2-notifications';

// Show a success toast instantly
ToastUtility.show('File saved successfully', 'Success', 3000);

// Show an error toast
ToastUtility.show('Connection failed', 'Error', 5000);

Common Patterns

Semantic Type Messages

Use severity property with Normal, Success, Info, Warning, or Error for visual differentiation.

let msg: Message = new Message({
  content: 'Operation completed',
  severity: 'Success',
  variant: 'Outlined'
});
msg.appendTo('#msg');

Dismissible Messages

Set showCloseIcon: true and showCloseButton: true (for Toast) to let users manually dismiss notifications.

let toastObj: Toast = new Toast({
  content: 'Your session will expire soon',
  showCloseButton: true,
  timeOut: 0
});
toastObj.appendTo('#toast');
toastObj.show();

Loading States with Skeleton

Display skeleton placeholders during content loading, then hide them when content is ready.

let skeleton: Skeleton = new Skeleton({
  shape: 'Rectangle',
  width: '100%',
  height: '200px',
  shimmerEffect: 'Pulse'
});
skeleton.appendTo('#skeleton');

Static/Persistent Toasts

Set timeOut: 0 with showCloseButton: true for notifications users must explicitly dismiss.

let toastObj: Toast = new Toast({
  content: 'Please review and confirm',
  timeOut: 0,
  showCloseButton: true
});
toastObj.appendTo('#toast');
toastObj.show();

Action-Required Toasts

Use the buttons property to add Ignore/Confirm/Undo buttons.

let toastObj: Toast = new Toast({
  content: 'Delete this file?',
  buttons: [{
    model: { content: 'Yes' },
    click: () => { /* handle yes */ }
  }, {
    model: { content: 'No' },
    click: () => toastObj.hide()
  }]
});
toastObj.appendTo('#toast');
toastObj.show();

Multiple Toast Positions

Display different toast instances at different screen positions.

let topToast: Toast = new Toast({
  content: 'Top notification',
  position: { X: 'Center', Y: 'Top' }
});
topToast.appendTo('#top-toast');
topToast.show();
