5 Dec 20244 minutes to read

The following section explains how to create a simple Badge component using styles and Badge’s basic usage.

Dependencies

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

|-- @syncfusion/ej2-notifications

Installation and configuration

You can use Create-react-app to setup the applications. To install create-react-app run the following command.

npm install -g create-react-app

To set-up a React application in TypeScript environment, run the following command.

npx create-react-app my-app --template typescript

cd my-app

npm start

To set-up a React application in JavaScript environment, run the following command.

npx create-react-app my-app

cd my-app

npm start

Adding Syncfusion packages

All the available Essential JS 2 packages are published in npmjs.com public registry.

To install Badge component, use the following command

npm install @syncfusion/ej2-notifications --save

Adding CSS Reference

Badge CSS files are available in the ej2-notifications package folder. Import the Badge component’s required CSS references as follows in src/App.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 component styles.

Initialize the Badge Component

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

import * as React from 'react';
import * as ReactDOM from "react-dom";
import './App.css';

function App() {
  return (
    <h1>Badge Component <span className="e-badge e-badge-primary">New</span></h1>
  );
}
export default App;
ReactDOM.render(<App />, document.getElementById("element"));

Run the application

Run the application in the browser using the following command:

npm start

Output will be as follows:

index.jsx
index.tsx
index.html
index.css
import * as React from "react";
import * as ReactDOM from "react-dom";
import "./index.css";
function App() {
    return (<h1>Badge Component <span className="e-badge e-badge-primary">New</span></h1>);
}
export default App;
ReactDOM.render(<App />, document.getElementById("element"));
import * as React from "react";
import * as ReactDOM from "react-dom";

function App() {
  return (
    <h1>Badge Component <span className="e-badge e-badge-primary">New</span></h1>
  );
}
export default App;
ReactDOM.render(<App />, document.getElementById("element"));
