ReactJS Blueprint FileInput 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. 
FileInput Component provides a way for users to upload files to our application. We can use the following approach in ReactJS to use the ReactJS Blueprint FileInput Component.

FileInput Props:

• buttonText: It is used to denote the button text.
• disabled: It is used to indicate whether the file input is non-interactive or not.
• fill: It is used to indicate whether the file input should take up the full width of its container or not.
• hasSelection: It is used to indicate whether the user has made a selection in the input or not.
• inputProps: It is used to denote the props to pass to the child input.
• large: It is used to indicate whether the file input should appear with large styling or not.
• onInputChange: It is a callback function that is triggered on <input> change events.
• text: It is used to denote the text to display.

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.

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

function App() {
    return (
        <div style={{
            display: 'block', width: 500, padding: 30
        }}>
            <h4>ReactJS Blueprint FileInput Component</h4>
            <FileInput text={'Please upload your file'} buttonText={'Upload'} />
        </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:
