How to make URL Shortner in JS

By Piyush Gupta

Creating a URL shortener with HTML, CSS, and JavaScript involves building a simple front-end interface that interacts with a back-end server. Below is an example of how you can create a basic front-end using HTML, CSS, and JavaScript that communicates with the previously mentioned Node.js server.

Explanation

HTML:
- Basic structure with an input field for the original URL, a button to trigger the shortening process, and a div to display the shortened URL.
CSS:
- Simple styling to center the content and give it a clean look.
JavaScript:
- Fetch API to send a POST request to the server with the original URL.
- Displays the shortened URL as a clickable link.

How It Works

User Interface:
- The user enters a URL in the input field.
- When the user clicks the “Shorten URL” button, the shortenUrl function is triggered.
JavaScript Function (shortenUrl):
- Reads the input value.
- Sends a POST request to the /shorten endpoint of the Node.js server with the original URL.
- Waits for the server to respond with the shortened URL.
- Displays the shortened URL in the result div as a clickable link.
Server:
- The server processes the POST request, saves the original URL with a generated short URL, and responds with the short URL.

Testing

Open your index.html file in a browser.
Ensure your Node.js server is running (node server.js).
Enter a URL in the input field and click “Shorten URL”.
The shortened URL should appear below, and clicking it should redirect to the original URL.

This setup provides a complete example of how to create a URL shortener using HTML, CSS, and JavaScript for the front-end, and Node.js with Express for the back-end.
