<img>tags - RESTful API design for consistent usage
Technical Implementation
API Endpoints
The service provides a comprehensive set of endpoints for image management:
// Upload endpoint
app.post('/upload', upload.single('image'), (req, res) => {
if (!req.file) {
return res.status(400).json({
success: false,
message: 'No file uploaded'
})
}
const fileInfo = {
filename: req.file.filename,
originalName: req.file.originalname,
size: req.file.size,
url: `${req.protocol}://${req.get('host')}/images/${req.file.filename}`,
directUrl: `${req.protocol}://${req.get('host')}/images/${req.file.filename}`
}
res.json({
success: true,
message: 'SVG image uploaded successfully',
data: fileInfo
})
})
Server Architecture
- Express.js Backend: Lightweight and fast server setup
- Multer Integration: Efficient file upload handling
- File System Storage: Local storage with organized file structure
- CORS Configuration: Cross-origin resource sharing enabled
- Error Handling: Comprehensive error responses and validation
Frontend Integration Examples
The API can be easily integrated into any project:
HTML Usage:
<img
src="https://ccimageapi.netlify.app/images/your-filename.svg"
alt="Icon"
width="32"
height="32"
/>
<!-- Theme-based usage -->
<img
src="https://ccimageapi.netlify.app/images/tech-stack-typescript-light.svg"
alt="TypeScript light icon"
className="hidden [html.light_&]:block"
/>
JavaScript/React Integration:
// Fetch available images
const fetchImages = async () => {
const response = await fetch('https://ccimageapi.netlify.app/images/list')
const data = await response.json()
return data.images
}
// React component
function TechIcon({ technology, theme = 'light' }) {
const imageUrl = `https://ccimageapi.netlify.app/images/tech-stack-${technology}-${theme}.svg`
return (
<img
src={imageUrl}
alt={`${technology} ${theme} icon`}
width={32}
height={32}
/>
)
}
