Installation and Configuration

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

‘react-scripts-ts’ is used for creating React app with typescript.

Adding Syncfusion packages

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

To install Switch component, use the following command

npm install @syncfusion/ej2-react-buttons --save

Adding Switch component to the Application

To include Switch component in your application import the SwitchComponent from ej2-react-buttons package in App.tsx.

Add Switch component in application as shown in below code example.

// Import the Switch.
import { SwitchComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import './App.css';

// To render Switch.
export default class App extends React.Component<{}, {}> {
  public render() {
    return (
      <SwitchComponent />
    );
  }
}

// Import the Switch.
import { SwitchComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import './App.css';
// To render Switch.
export default class App extends React.Component {
    render() {
        return (<SwitchComponent />);
    }
}

Adding CSS Reference

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
