ReactJS Blueprint Checkbox Component

BlueprintJS is a React-based UI toolkit for the web. This library is very optimized and popular for building interfaces that are complex data-dense for desktop applications. Checkbox Component provides a way for users to toggle between checked, unchecked, and indeterminate states. We can use the following approach in ReactJS to use the ReactJS Blueprint Checkbox Component.

Checkbox Props:

• alignIndicator: It is used for the alignment of the indicator within the container.
• checked: It is used to indicate whether the control is checked or not.
• children: It is used to denote the JSX label for the control.
• className: It is used to denote a space-delimited list of class names to pass along to a child element.
• defaultChecked: It is used to indicate whether the control is initially checked (uncontrolled mode) or not.
• defaultIndeterminate: It is used to indicate whether this checkbox is initially indeterminate (uncontrolled mode) or not.
• disabled: It is used to indicate whether the control is non-interactive or not.
• indeterminate: It is used to indicate whether this checkbox is indeterminate, or partially checked.
• inline: It is used to indicate whether the control should appear as an inline element or not.
• inputRef: It is used to denote the ref handler that receives HTML <input> element backing this component.
• label: It is used to denote the text label for the control.
• labelElement: It is used to denote the JSX Element label for the control.
• large: It is used to indicate whether this control should use large styles or not.
• onChange: It is used to denote the event handler invoked when the input value is changed.
• tagName: It is used to denote the name of the HTML tag that wraps the checkbox.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command:

cd foldername

Step 3: After creating the ReactJS application, Install the required module using the following command:

npm install @blueprintjs/core

Project Structure: It will look like the following.

Project Structure

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

Javascript

import React from 'react'
import '@blueprintjs/core/lib/css/blueprint.css';
import { Checkbox } from "@blueprintjs/core";

function App() {

    return (
        <div style={{
            display: 'block', width: 500, padding: 30
        }}>
            <h4>ReactJS Blueprint Checkbox Component</h4>
            Favourite Food:
            <Checkbox label="Fast Food" defaultIndeterminate={true} />
            <Checkbox label="Junk Food" />
            <Checkbox label="Sweet Food" />
            <Checkbox label="Spicy Food" />
        </div>
    );
}

export default App;

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
