ReactJS Blueprint InputGroup 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.

InputGroup Component provides a way for users to provide them a text input. It is a basic component to collect data from the user. We can use the following approach in ReactJS to use the ReactJS Blueprint InputGroup Component.

InputGroup Props:

• asyncControl: We can control the value of this input with asynchronous updates when this is set to true.
• className: It is used to denote the space-delimited list of class names to pass along to a child element.
• defaultValue: It is used to denote the initial value of the input, for uncontrolled usage.
• disabled: It is used to indicate whether or not the input is non-interactive.
• fill: It is used to indicate whether or not the component should take up the full width of its container.
• inputRef: It is used to denote the ref handler or a ref object that receives HTML <input> element backing this component.
• intent: It is used to denote the visual intent color to apply to the element.
• large: It is used to indicate whether or not this input should use large styles.
• leftElement: It is used to denote the element to render on the left side of an input.
• leftIcon: It is used to denote the name of an Icon to render on the left side of the input group just before the user cursor.
• onChange: It is used to denote the change event handler.
• placeholder: It is used to denote the placeholder text in the absence of any value.
• rightElement: It is used to denote the element to render on the right side of the input.
• round: It is used to indicate whether or not the input (and any buttons) should appear with rounded caps.
• small: It is used to indicate whether or not this input should use small styles.
• type: It is used to denote the HTML input type attribute.
• value: It is used to denote the form value of the input, for controlled usage.

TextArea Props:

• className: It is used to denote a space-delimited list of class names to pass along to a child element.
• fill: It is used to indicate whether or not the text area should take up the full width of its container.
• growVertically: It is used to indicate whether or not the text area should automatically grow vertically to accommodate content.
• inputRef: It is used to denote the ref handler that receives HTML <textarea> element backing this component.
• intent: It is used to denote the visual intent color to apply to element.
• large: It is used to indicate whether or not the text area should appear with large styling.
• small: It is used to indicate whether or not the text area should appear with small styling.

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.

App.js

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

function App() {
    return (
        <div style={{
            display: 'block', width: 400, padding: 30
        }}>
            <h4>ReactJS Blueprint TextInput Component</h4>
            <InputGroup
                disabled={false}
                leftIcon="user"
                onChange={() => { console.log("Called on change of value") }}
                placeholder="Enter your name"
            />
        </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:
