Getting started with Angular Badge component

27 Jul 20266 minutes to read

The following section explains the steps required to create a simple Badge component using styles and demonstrate its basic usage.

Note: This guide supports Angular 21 and other recent Angular versions. For detailed compatibility with other Angular versions, please refer to the Angular version support matrix. Starting from Angular 19, standalone components are the default, and this guide reflects that architecture.

Prerequisites

Ensure your development environment meets the System Requirements for Syncfusion Angular UI Components.

Dependencies

The Badge component is a pure CSS component and does not require additional dependencies to render.

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

SetUp the Angular application

A straightforward approach to beginning with Angular is to create a new application using the Angular CLI. Install Angular CLI globally with the following command:

npm install -g @angular/cli

Angular 21 Standalone Architecture: Standalone components are the default in Angular 21. This guide uses the modern standalone architecture. If you need more information about the standalone architecture, refer to the Standalone Guide.

Installing a specific version

To install a particular version of Angular CLI, use:

npm install -g @angular/[email protected]

Create a new application

With Angular CLI installed, execute this command to generate a new application:

ng new syncfusion-angular-app
  • This command will prompt you to configure settings like enabling Angular routing and choosing a stylesheet format.
? Which stylesheet format would you like to use? (Use arrow keys)
> CSS             [ https://developer.mozilla.org/docs/Web/CSS                     ]
  Sass (SCSS)     [ https://sass-lang.com/documentation/syntax#scss                ]
  Sass (Indented) [ https://sass-lang.com/documentation/syntax#the-indented-syntax ]
  Less            [ http://lesscss.org                                             ]
  • By default, a CSS-based application is created. Use SCSS if required:
ng new syncfusion-angular-app --style=scss
  • During project setup, when prompted for the Server-side rendering (SSR) option, choose the appropriate configuration.

Initial_setup

  • Select the required AI tool or ‘none’ if you do not need any AI tool.

Initial_setup

  • Navigate to your newly created application directory:
cd syncfusion-angular-app

Note: In Angular 19 and below, it uses app.component.ts, app.component.html, app.component.css etc. In Angular 20+, the CLI generates a simpler structure with src/app/app.ts, app.html, and app.css (no .component. suffixes).

Installing Syncfusion® Notifications package

Syncfusion®’s Angular component packages are available on npmjs.com. To use Syncfusion® Angular components, install the necessary package.

This guide uses the Angular Badge component for demonstration. Add the Angular Badge component component with:

ng add @syncfusion/ej2-angular-notifications

This command will perform the following configurations:

  • Add the @syncfusion/ej2-angular-notifications package and peer dependencies to your package.json.
  • Import the Badge component component in your application.
  • Register the default Syncfusion® material3 theme in angular.json.

For more details on version compatibility, refer to the Version Compatibility section.

Syncfusion® offers two package structures for Angular components:

  1. Ivy library distribution package format
  2. Angular compatibility compiler (ngcc), which is Angular’s legacy compilation pipeline.
    Syncfusion®’s latest Angular packages are provided as Ivy-compatible and suited for Angular 12 and above. To install the package, execute: 
    ng add @syncfusion/ej2-angular-notifications

    For applications not compiled with Ivy, use the ngcc tagged packages:

    The ngcc packages are still compatible with Angular CLI versions 15 and below. However, they may generate warnings suggesting the use of IVY compiled packages. Starting from Angular 16, support for the ngcc package has been completely removed. If you have further questions regarding ngcc compatibility, please refer to the following FAQ.

    npm add @syncfusion/[email protected]

Adding CSS reference

Themes for the Syncfusion® component can be applied using CSS files provided through npm theme packages. For available themes, refer to the Themes documentation.

Install the Material 3 theme package using the following npm command:

npm install @syncfusion/ej2-material3-theme

Then add the following CSS reference to the src/styles.css file. This is the default global stylesheet registered under styles in angular.json:

@import "@syncfusion/ej2-material3-theme/styles/material3.css";

Add the Badge to the application

Use the following snippet in the src/app/app.ts file to import the Badge component.

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

@Component({
  imports: [],
  standalone: true,
  selector: 'app-root',
  template: `<div id='element'><h1>Badge Component <span class="e-badge">New</span></h1></div>`
})

export class App { }

Run the application

Run the application in the browser using the following command.

ng serve

The following example shows a basic badge component.

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

@Component({
    imports: [],
    standalone: true,
    selector: 'app-root',
    template: `<div id='element'><h1>Badge Component <span class="e-badge e-badge-primary">New</span></h1></div>`
})

export class AppComponent { }
@import '/node_modules/@syncfusion/ej2-base/styles/material3.css';
@import '/node_modules/@syncfusion/ej2-notifications/styles/material3.css';
@import '/node_modules/@syncfusion/ej2-angular-notifications/styles/material3.css';

#container {
    visibility: hidden;
}

#element {
    display: flex;
    width: 400px;
    margin: auto;
    border: 1px solid #dddddd;
    border-radius: 3px;
    justify-content: center;
}

#loader {
    color: #008cff;
    height: 40px;
    left: 45%;
    position: absolute;
    top: 45%;
    width: 30%;
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
