Step 2: Configure Cloudinary

const cloudinary = require('cloudinary').v2;

cloudinary.config({
  cloud_name: 'YOUR_CLOUD_NAME',
  api_key: 'YOUR_API_KEY',
  api_secret: 'YOUR_API_SECRET',
});

module.exports = cloudinary;

Copy after login

Step 3: Set Up Environment Variables

CLOUD_NAME=your-cloud-name
API_KEY=your-api-key
API_SECRET=your-api-secret

Copy after login
npm install dotenv
Copy after login
require('dotenv').config();

cloudinary.config({
  cloud_name: process.env.CLOUD_NAME,
  api_key: process.env.API_KEY,
  api_secret: process.env.API_SECRET,
});

Copy after login

Step 4: Upload Images to Cloudinary

const cloudinary = require('./config');

async function uploadImage(imagePath) {
  try {
    const result = await cloudinary.uploader.upload(imagePath, {
      folder: 'samples', // Optional: specify the folder to store images
    });
    console.log('Image uploaded successfully:', result.url);
    return result.url;
  } catch (error) {
    console.error('Error uploading image:', error);
  }
}

// Example usage
uploadImage('path/to/your/image.jpg');

Copy after login

Step 5: Transform Images with Cloudinary

const transformedImageUrl = cloudinary.url('sample.jpg', {
  width: 400,
  height: 300,
  crop: 'fill',
});

console.log('Transformed Image URL:', transformedImageUrl);

Copy after login

Step 6: Handle File Uploads in Your Application

npm install multer

Copy after login
const multer = require('multer');
const upload = multer({ dest: 'uploads/' }); // Temporary folder for uploaded files

app.post('/upload', upload.single('image'), async (req, res) => {
  try {
    const imagePath = req.file.path;
    const imageUrl = await uploadImage(imagePath);
    res.json({ imageUrl });
  } catch (error) {
    res.status(500).json({ error: 'Failed to upload image' });
  }
});

Copy after login

Step 7: Optimize and Deliver Media Assets

const optimizedImageUrl = cloudinary.url('sample.jpg', {
  fetch_format: 'auto',
  quality: 'auto',
});

console.log('Optimized Image URL:', optimizedImageUrl);

Copy after login

Conclusion

Integrating Cloudinary into your Node.js project is straightforward and opens up a world of media management features. Whether you’re dealing with images or videos, Cloudinary’s powerful API makes it easy to optimize, transform, and deliver assets efficiently.
