File Explorer is a common feature in many applications that allows users to navigate through files and folders on their computer. In this tutorial, we will build a simple file explorer component using React JS.

To get started, make sure you have Node.js and npm installed on your computer. If you haven’t already, you can download Node.js from the official website.

1. Setting up the project:

First, we need to create a new React project. Open your terminal and run the following command to create a new React project using Create React App.

npx create-react-app file-explorer

Once the project is created, navigate to the project directory by running:

cd file-explorer

1. Creating the File Explorer component:

Inside the src folder, create a new folder called components. Inside the components folder, create a new file called FileExplorer.js. This file will contain our File Explorer component.

Add the following code to the FileExplorer.js file:

import React from 'react';

const FileExplorer = () => {
  return (
    <div>
      File Explorer Component
    </div>
  );
};

export default FileExplorer;

1. Importing the File Explorer component:

Now, import the FileExplorer component in the App.js file and render it inside the App component.

import React from 'react';
import FileExplorer from './components/FileExplorer';

function App() {
  return (
    <div>
      <h1>File Explorer App</h1>
      <FileExplorer />
    </div>
  );
}

export default App;

1. Styling the File Explorer component:

Next, let’s add some basic styling to the FileExplorer component to make it look like a file explorer. You can do this by adding CSS to the FileExplorer.js file or by creating a separate CSS file.

For example, you can add the following CSS code to FileExplorer.js:

.FileExplorer {
  padding: 10px;
  border: 1px solid #ccc;
  border-radius: 5px;
}

And update the FileExplorer component to apply the CSS class:

import React from 'react';
import './FileExplorer.css';

const FileExplorer = () => {
  return (
    <div className="FileExplorer">
      File Explorer Component
    </div>
  );
};

export default FileExplorer;

1. Adding file and folder components:

To make our file explorer functional, we need to create components for files and folders. Inside the components folder, create two new files called File.js and Folder.js.

Add the following code to File.js and Folder.js:

File.js:

import React from 'react';

const File = ({ name }) => {
  return (
    <div>
      {name}
    </div>
  );
};

export default File;

Folder.js:

import React from 'react';

const Folder = ({ name }) => {
  return (
    <div>
      {name}
    </div>
  );
};

export default Folder;

1. Updating the File Explorer component:

Now, import the File and Folder components into the FileExplorer.js file and render a list of files and folders.

import React from 'react';
import './FileExplorer.css';
import File from './File';
import Folder from './Folder';

const FileExplorer = () => {
  const files = ['file1.txt', 'file2.txt'];
  const folders = ['folder1', 'folder2'];

  return (
    <div className="FileExplorer">
      <h2>Files:</h2>
      {files.map(file => <File key={file} name={file} />)}

      <h2>Folders:</h2>
      {folders.map(folder => <Folder key={folder} name={folder} />)}
    </div>
  );
};

export default FileExplorer;

1. Testing the File Explorer component:

Finally, run the following command in the terminal to start the development server and open the File Explorer app in your browser:

npm start

You should see the File Explorer component with a list of files and folders displayed on the screen.

Congratulations! You have successfully built a simple file explorer component using React JS. You can further customize and enhance the functionality of the file explorer by adding features such as file uploads, file downloads, and folder navigation.
