Build a URL shortener in 20 lines.
Use Express.js for your server. Use free APIs from gadgethumans.com.
How it works:
- Use a Map to store URLs.
- Fetch a UUID for unique IDs.
- Split the UUID to get a short code.
- Save the long URL with this code.
- Create a QR code link for the short URL.
- Redirect users to the original site.
No API keys needed. No complex setup.
