ReactJS Blueprint InputGroup Component

Last Updated : 10 Jul, 2021

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.

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;
