How to use react-dropzone module in ReactJS ?

React-Dropzone module is a simple React hook that is used to create an HTML5-compliant drag-drop zone for n number of files. We can use this module to provide a way for users to drop and drop their multiple files, and then we can handle these files as per the business requirement.

Prerequisites:

• NodeJS or NPM
• React JS

Approach:

The integration of the "react-dropzone" module into a ReactJS application. The "useDropzone" wrapper component is imported to obtain dropzone property getters. These getters are applied to an Input element, creating a drag-and-drop zone. Clicking on the text "Click to select the file or drag-and-drop the file here!!" prompts the user to select a file, enabling subsequent operations based on business requirements.

Steps to Create the 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: Install the required module using the following command:

npm install react-dropzone 

Project Structure:

The update dependencies in package.json file will look like:

"dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-dropzone": "^14.2.3",,
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4",
}

Example: Now write down the following code in the App.js file

import React, { useCallback } from 'react'
import { useDropzone } from 'react-dropzone'

export default function App() {

  const onDrop = useCallback(acceptedFiles => {
    alert(acceptedFiles[0].name)
    console.log("Now you can do anything with"+
                " this file as per your requirement")
  }, [])

  const { getInputProps, getRootProps } = useDropzone({ onDrop })

  return (
    <div style={{ display: 'block', width: 700, padding: 30 }}>
      <h4>React-Dropzone Module Demo</h4>
      <div {...getRootProps()}>
        <input {...getInputProps()} />
        <p>Click to select file or 
           drag-and-drop the file here!!</p>

      </div>
    </div>
  );
}

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
