Prerequisites
Before diving in, ensure that you have:
- Node.js installed on your system
- A basic Node.js application setup
- A Cloudinary account (you can sign up here if you don’t have one)
Step 1: Install Cloudinary SDK
npm install cloudinary
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;
Step 3: Set Up Environment Variables
CLOUD_NAME=your-cloud-name
API_KEY=your-api-key
API_SECRET=your-api-secret
npm install dotenv
require('dotenv').config();
cloudinary.config({
cloud_name: process.env.CLOUD_NAME,
api_key: process.env.API_KEY,
api_secret: process.env.API_SECRET,
});
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');
Step 5: Transform Images with Cloudinary
const transformedImageUrl = cloudinary.url('sample.jpg', {
width: 400,
height: 300,
crop: 'fill',
});
console.log('Transformed Image URL:', transformedImageUrl);
Step 6: Handle File Uploads in Your Application
npm install multer
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' });
}
});
Step 7: Optimize and Deliver Media Assets
const optimizedImageUrl = cloudinary.url('sample.jpg', {
fetch_format: 'auto',
quality: 'auto',
});
console.log('Optimized Image URL:', optimizedImageUrl);
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.
Happy coding!
