Images Browse & Drag and Drop with Preview – React Component – Next.js

Introduction

In this tutorial, we will learn how to use the "Images Browse & Drag and Drop with Preview" React component in a Next.js project. This component allows users to browse and select images from their local file system, and then preview them before uploading. We will go through a step-by-step process to integrate this component into our Next.js application.

Step 1: Install the Required Packages

To use the "Images Browse & Drag and Drop with Preview" component, we need to install the following packages:

1. react-dropzone: This package provides the drag and drop functionality for uploading files.
2. react-preview-component: This package provides the preview functionality for displaying the uploaded images.

Run the following command in your terminal to install the packages:

npm install react-dropzone react-preview-component

Step 2: Create a New Next.js Project

If you haven't already, create a new Next.js project by running the following command:

npx create-next-app my-app

Step 3: Create a New Component

Create a new component named ImageUploader.js in the components directory:

// components/ImageUploader.js
import React, { useState } from 'react';
import { useDropzone } from 'react-dropzone';
import PreviewComponent from 'react-preview-component';

function ImageUploader() {
  const [files, setFiles] = useState([]);
  const { getRootProps, getInputProps, isDragActive } = useDropzone({
    accept: 'image/*',
    onDrop: (acceptedFiles) => {
      setFiles(acceptedFiles.map((file) => Object.assign(file, {
        preview: URL.createObjectURL(file),
      })));
    },
  });

  return (
    <div {...getRootProps()} className="dropzone">
      <input {...getInputProps()} />
      {
        isDragActive? <p>Drop the images here...</p> : <p>Drag and drop the images here, or click to select</p>
      }
      <ul>
        {files.map((file, index) => (
          <li key={index}>
            <PreviewComponent src={file.preview} alt={file.name} />
            <p>{file.name}</p>
          </li>
        ))}
      </ul>
    </div>
  );
}

export default ImageUploader;

Step 4: Use the ImageUploader Component

Create a new page named index.js in the pages directory:

// pages/index.js
import ImageUploader from '../components/ImageUploader';

function HomePage() {
  return (
    <div>
      <ImageUploader />
    </div>
  );
}

export default HomePage;

Step 5: Add the Component to the App

Open the app.js file and add the following code:

// pages/_app.js
import ImageUploader from '../components/ImageUploader';

function MyApp({ Component, pageProps }) {
  return (
    <div>
      <Component {...pageProps} />
      <ImageUploader />
    </div>
  );
}

export default MyApp;

Step 6: Run the Application

Run the following command in your terminal to start the application:

npm run dev

Open your web browser and navigate to http://localhost:3000. You should see the "Images Browse & Drag and Drop with Preview" component, which allows you to browse and select images from your local file system, and then preview them before uploading.

That's it! You have successfully integrated the "Images Browse & Drag and Drop with Preview" React component into your Next.js application.
