Getting started with EJ2 TypeScript Badge control

7 May 20255 minutes to read

This section explains how to create a simple Badge control and configure its available functionalities in TypeScript using the Essential^® JS 2 quickstart seed repository.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

Dependencies

Install the following required dependent package to render the Badge control.

|-- @syncfusion/ej2-notifications

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion^® JavaScript (Essential^® JS 2) quickstart project from GitHub.

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion^® JavaScript packages

Syncfusion^® JavaScript (Essential^® JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion^® JavaScript (Essential^® JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion^® CSS styles

The badge CSS files are available in the ej2-notifications package folder. This can be referenced in the ~/src/styles/styles.css file of your application using the following code.

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

We can also use CRG to generate combined control styles.

Add badge into application

Open the application in Visual Studio Code and add the Syncfusion^® JavaScript UI controls.

Add an HTML span element with e-badge class inside any wrapper element (h1) into your index.html.

[src/index.html]

index.html
<h1>Badge Control <span class="e-badge">New</span></h1>

Run the application

Run the application in the browser using the following command.

npm start

The following example shows a basic badge control.
