Getting started with EJ2 TypeScript Badge control

13 Jan 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.
