description	Comprehensive guide for implementing Syncfusion EJ2 JavaScript Notification components including Message, Skeleton, and Toast. Use this when displaying contextual messages with severity indicators (Normal, Success, Info, Warning, Error) and display variants (Text, Outlined, Filled); creating animated loading placeholders with shapes (Circle, Square, Rectangle, Text) and shimmer effects (Wave, Pulse, Fade); configuring toast notifications with positioning, animations, templates, and dismissal patterns; or customizing notification appearance and accessibility.

Message Component

Purpose: Displays contextual messages with visual severity indicators (icons and colors) to communicate importance and context to end users. Supports five severity levels, three visual variants, close-icon dismissal, custom templates, and full accessibility compliance.

Package: @syncfusion/ej2-notifications

Quick Example

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

let msg: Message = new Message({
  content: 'Please read the comments carefully',
  severity: 'Info'
});
msg.appendTo('#msg');

Skeleton Component

Purpose: Renders animated placeholder shapes that mimic the layout of loading content. Reduces perceived load time and communicates progress to users with configurable shapes, shimmer animations, and full accessibility support.

Package: @syncfusion/ej2-notifications

Quick Example

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

let skeleton: Skeleton = new Skeleton({
  shape: 'Circle',
  width: '48px'
});
skeleton.appendTo('#skeleton');

• skeleton-shapes.md - Shape types (Circle, Square, Rectangle, Text)
• skeleton-shimmer-effect.md - Shimmer animations (Wave, Pulse, Fade)
• skeleton-styles.md - CSS customization and visibility
• skeleton-accessibility.md - WAI-ARIA attributes and reduced-motion support
• skeleton-api.md - Complete API reference

---

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();
