Setting Up the Project

Before diving into the code, ensure that your React project is set up correctly. This guide assumes you have a React project initialized with dependencies like react-router-dom and axios for handling routing and HTTP requests, respectively.

Installing Necessary Dependencies

npm install react-router-dom axios

1	npm install react-router-dom axios

Implementing Photo Upload

Understanding the Project Structure

The project structure plays a pivotal role in organizing your code for scalability and maintainability. Here’s a brief overview of the essential files involved in the photo upload functionality:

src/
├── client/
│   └── client.js
├── pages/
│   └── albums/
│       ├── albumUpload.js
│       ├── albumShow.js
│       └── albums.js
├── components/
│   └── Loader.js
└── App.js

src/

├── client/

│ └── client.js

├── pages/

│ └── albums/

│ ├── albumUpload.js

│ ├── albumShow.js

│ └── albums.js

├── components/

│ └── Loader.js

└── App.js

client.js: Handles HTTP requests.
albumUpload.js: Manages the photo upload interface and logic.
Loader.js: Displays the processing animation.
App.js: Sets up routing for different pages.

Modifying the Album Upload Component

The albumUpload.js component is responsible for handling the photo upload process. We’ll walk through the key modifications made to enhance its functionality.

Step 1: Import Necessary Hooks and Modules

import React, { useState } from 'react';
import { useLocation, useNavigate } from 'react-router-dom';
import fetchPostFileUploadWithAuth from '../client/client';
import Loader from '../components/Loader';

import React, { useState } from 'react';

import { useLocation, useNavigate } from 'react-router-dom';

import fetchPostFileUploadWithAuth from '../client/client';

import Loader from '../components/Loader';

Step 2: Reading ID from URL Parameters

To dynamically handle uploads for different albums, we need to extract the ID from the URL.

const location = useLocation();
const navigate = useNavigate();
const queryParams = new URLSearchParams(location.search);
const albumId = queryParams.get('ID');

const location = useLocation();

const navigate = useNavigate();

const queryParams = new URLSearchParams(location.search);

const albumId = queryParams.get('ID');

Step 3: Setting Up State for Processing

We’ll use React’s useState hook to manage the processing state, which determines whether to show the upload button or the loading animation.

const [processing, setProcessing] = useState(false);

1	const [processing, setProcessing] = useState(false);

Step 4: Handling the Upload Process

const handleUpload = async (event) => {
    setProcessing(true);
    const formData = new FormData();
    Array.from(event.target.files).forEach(file => {
        formData.append('photos', file);
    });

    try {
        const response = await fetchPostFileUploadWithAuth(`/albums/${albumId}/photo-upload`, formData);
        console.log(response.data);
        navigate(`/albums/show?ID=${albumId}`);
    } catch (error) {
        console.error('Upload failed:', error);
    } finally {
        setProcessing(false);
    }
};

const handleUpload = async (event) => {

setProcessing(true);

const formData = new FormData();

Array.from(event.target.files).forEach(file => {

formData.append('photos', file);

});

try {

const response = await fetchPostFileUploadWithAuth(`/albums/${albumId}/photo-upload`, formData);

console.log(response.data);

navigate(`/albums/show?ID=${albumId}`);

} catch (error) {

console.error('Upload failed:', error);

} finally {

setProcessing(false);

}

};

Adding Comments to the Code

Adding comments to your code aids in readability and maintenance. Here’s the annotated version of the handleUpload function:

const handleUpload = async (event) => {
    // Set processing state to true to show the loader
    setProcessing(true);

    // Create a new FormData object
    const formData = new FormData();

    // Append each selected file to the FormData
    Array.from(event.target.files).forEach(file => {
        formData.append('photos', file);
    });

    try {
        // Make a POST request to upload photos
        const response = await fetchPostFileUploadWithAuth(`/albums/${albumId}/photo-upload`, formData);
        console.log(response.data); // Log the successful response

        // Navigate to the album show page after successful upload
        navigate(`/albums/show?ID=${albumId}`);
    } catch (error) {
        console.error('Upload failed:', error); // Log any errors during upload
    } finally {
        // Reset processing state to false to hide the loader
        setProcessing(false);
    }
};

const handleUpload = async (event) => {

// Set processing state to true to show the loader

setProcessing(true);

// Create a new FormData object

const formData = new FormData();

// Append each selected file to the FormData

Array.from(event.target.files).forEach(file => {

formData.append('photos', file);

});

try {

// Make a POST request to upload photos

const response = await fetchPostFileUploadWithAuth(`/albums/${albumId}/photo-upload`, formData);

console.log(response.data); // Log the successful response

// Navigate to the album show page after successful upload

navigate(`/albums/show?ID=${albumId}`);

} catch (error) {

console.error('Upload failed:', error); // Log any errors during upload

} finally {

// Reset processing state to false to hide the loader

setProcessing(false);

}

};

Integrating the Upload Interface

In your component’s return statement, conditionally render the upload button or the loader based on the processing state.

return (
    <div className="upload-container">
        <input
            type="file"
            multiple
            onChange={handleUpload}
            disabled={processing}
        />
        {!processing ? (
            <button onClick={handleUpload}>Upload Photos</button>
        ) : (
            <Loader />
        )}
    </div>
);

return (

<input

type="file"

multiple

onChange={handleUpload}

disabled={processing}

{!processing ? (

<button onClick={handleUpload}>Upload Photos</button>

) : (

)}

</div>

);

Enhancing User Experience with Processing Animation

Introducing Circular Progress Indicators

We’ll use a Loader component to display a circular progress bar during the upload process.

Creating the Loader Component

// src/components/Loader.js
import React from 'react';
import CircularProgress from '@material-ui/core/CircularProgress';

const Loader = () => (
    <div className="loader">
        <CircularProgress />
        <p>Uploading...</p>
    </div>
);

export default Loader;

// src/components/Loader.js

import React from 'react';

import CircularProgress from '@material-ui/core/CircularProgress';

const Loader = () => (

<p>Uploading...</p>

</div>

);

export default Loader;

Managing State for Processing

As seen earlier, the processing state determines whether the loader or the upload button is displayed. When a user initiates an upload, processing is set to true, triggering the loader.

Testing the Upload Functionality

After implementing the upload feature with processing animation, it’s crucial to test its functionality:

Navigate to the Upload Page: Access the album upload page in your application.
Select Photos: Use the drag-and-drop interface or the file selector to choose photos.
Initiate Upload: Click the “Upload Photos” button.
Observe the Loader: Ensure the circular progress indicator appears during the upload.
Verify Redirection: After a successful upload, confirm that the application redirects to the album show page.
Check Backend Response: Inspect the console to verify that the backend responds appropriately.

Handling Errors

If an upload fails, ensure that the application handles the error gracefully, possibly by displaying an error message to the user.

} catch (error) {
    console.error('Upload failed:', error);
    alert('There was an issue uploading your photos. Please try again.');
}

} catch (error) {

console.error('Upload failed:', error);

alert('There was an issue uploading your photos. Please try again.');

}

Conclusion

Implementing photo uploads with processing animations in a React application enhances both functionality and user experience. By providing visual feedback during uploads, users remain informed, leading to higher satisfaction and engagement. This guide walked you through setting up the project, implementing the upload feature, integrating a circular progress indicator, and testing the functionality to ensure robustness.
