Getting started with Angular Skeleton component

27 Sep 20234 minutes to read

This section explains how to create a simple Skeleton and demonstrate the basic usage of the Skeleton component in an Angular environment.

Dependencies

The list of dependencies required to use the Skeleton component in your application is given as follows:

|-- @syncfusion/ej2-angular-notifications
    |-- @syncfusion/ej2-angular-base

Setup Angular environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

npm install -g @angular/cli

Create an Angular application

Start a new Angular application using below Angular CLI command.

ng new my-app

cd my-app

Installing Syncfusion Notifications package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

1. Ivy library distribution package format
2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-notifications package to the application.

npm install @syncfusion/ej2-angular-notifications --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-notifications@ngcc package to the application.

npm install @syncfusion/ej2-angular-notifications@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

@syncfusion/ej2-angular-notifications:"20.3.0.47-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Adding Skeleton module

After installing the package, the component modules are ready to configure in your application from installed syncfusion package. Syncfusion Angular package provides two different types of ngModules.

Refer to Ng-Module to learn about ngModules.

Refer the following snippet to import the SkeletonModule in app.module.ts from the @syncfusion/ej2-angular-notifications.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
// Imported syncfusion SkeletonModule from ej2-angular-notifications package
import { SkeletonModule } from '@syncfusion/ej2-angular-notifications';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        AppRoutingModule,
        // Registering EJ2 Skeleton Module
        SkeletonModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }

Add Skeleton into application

Modify the template in app.component.ts file to render the Skeleton component.

[src/app/app.component.ts]

import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    template: `<ejs-skeleton height='15px'></ejs-skeleton>`
})

export class AppComponent { }

Adding CSS reference

The following CSS files are available in ../node_modules/@syncfusion package folder. This can be referenced in [src/styles.css] using following code.

      @import '../node_modules/@syncfusion/ej2-base/styles/material.css';
      @import '../node_modules/@syncfusion/ej2-angular-notifications/styles/material.css';

Running the application

Run the application in the browser using the following command:

ng serve

The following example shows a basic Skeleton component.

app.component.ts

import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    template: `<ejs-skeleton height='15px'></ejs-skeleton>`
})

export class AppComponent { }

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { SkeletonModule } from '@syncfusion/ej2-angular-notifications';
import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, 
        SkeletonModule
    ],
    declarations: [AppComponent ],
    bootstrap: [AppComponent]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
