  `
})
export class AppComponent {
  @ViewChild('msg') msg!: MessageComponent;
  isClosed = false;

Quick Start

import { Component } from '@angular/core';
import { SkeletonModule } from '@syncfusion/ej2-angular-notifications';

@Component({
  imports: [SkeletonModule],
  standalone: true,
  selector: 'app-root',
  template: `
    <div>
      <h2>Loading User Profile...</h2>
      <!-- Avatar skeleton -->
      <ejs-skeleton shape="Circle" width="60px"></ejs-skeleton>

      <!-- Content skeleton -->
      <ejs-skeleton shape="Rectangle" width="100%" height="150px"></ejs-skeleton>
    </div>
  `
})
export class AppComponent {}

---

Common Patterns

Pattern 1: Card Loading Skeleton

Display a skeleton layout matching a card component during data loading:

@Component({
  selector: 'app-card-skeleton',
  template: `
    <div class='card-skeleton'>
      <!-- Avatar -->
      <div class='avatar-section'>
        <ejs-skeleton shape="Circle" width="50px"></ejs-skeleton>
      </div>
      <!-- Content -->
      <div class='content-section'>
        <ejs-skeleton width="60%" height="12px"></ejs-skeleton>
        <ejs-skeleton width="40%" height="12px"></ejs-skeleton>
        <ejs-skeleton width="100%" height="80px"></ejs-skeleton>
      </div>
      <!-- Actions -->
      <div class='action-section'>
        <ejs-skeleton shape="Rectangle" width="30%" height="36px"></ejs-skeleton>
      </div>
    </div>
  `
})
export class CardSkeletonComponent {}

Pattern 2: List Loading with Pulse Effect

Show multiple skeleton rows with a pulsing shimmer effect:

@Component({
  selector: 'app-list-skeleton',
  template: `
    <div class='list-skeleton'>
      <div class='list-item' *ngFor="let item of [1,2,3,4,5]">
        <ejs-skeleton shape="Circle" width="40px" shimmerEffect="Pulse"></ejs-skeleton>
        <div class='item-content'>
          <ejs-skeleton width="50%" height="14px" shimmerEffect="Pulse"></ejs-skeleton>
          <ejs-skeleton width="30%" height="12px" shimmerEffect="Pulse"></ejs-skeleton>
        </div>
      </div>
    </div>
  `
})
export class ListSkeletonComponent {}

Pattern 3: Conditional Skeleton Rendering

Show skeleton while loading, hide when content is ready:

@Component({
  selector: 'app-conditional-skeleton',
  template: `
    <!-- Show skeleton while loading -->
    <div *ngIf="isLoading">
      <ejs-skeleton shape="Rectangle" width="100%" height="200px" 
                    shimmerEffect="Wave"></ejs-skeleton>
    </div>
    <!-- Show content when loaded -->
    <div *ngIf="!isLoading">
      <img [src]="imageUrl" alt="Loaded content">
    </div>
  `
})
export class ConditionalSkeletonComponent {
  isLoading = true;
  imageUrl = '';
  
  ngOnInit() {
    // Simulate loading
    setTimeout(() => {
      this.isLoading = false;
      this.imageUrl = 'assets/image.jpg';
    }, 2000);
  }
}
