Introduction

When working with URLs in your application, you may encounter situations where you need to display a short version of the URL to users. This can be particularly useful when dealing with long URLs that contain special characters, such as math and spaces. In this article, we will explore how to use URLs (not href) to display short versions of URLs in your application.

Understanding the Problem

When you need to display a short version of a URL, you may be tempted to use the href attribute in HTML. However, this approach has its limitations. The href attribute is primarily used to specify the URL of a hyperlink, and it does not provide a way to display a short version of the URL.

The Challenge of Displaying Short URLs

Displaying short URLs can be challenging when dealing with files in a source tree that have math and spaces in their names. For example, consider a file named "example 123.txt". When you need to display a short version of this URL, you may want to remove the spaces and display only the file name with the extension.

Solution: Using URLs to Display Short Versions

To display short versions of URLs, you can use the URL object in JavaScript. The URL object provides a way to manipulate URLs and extract their components.

Creating a Short URL

To create a short URL, you can use the URL object to extract the file name and extension from the original URL. Here is an example:

const originalUrl = "https://example.com/example 123.txt";
const url = new URL(originalUrl);
const shortUrl = url.pathname.replace(/ /g, "").split(".").slice(0, -1).join(".");
console.log(shortUrl); // Output: "example123"

In this example, we use the URL object to extract the file name and extension from the original URL. We then use the replace() method to remove the spaces from the file name and the split() method to separate the file name and extension. Finally, we use the slice() method to remove the extension and the join() method to combine the file name.

Displaying the Short URL

Once you have created a short URL, you can display it in your application using HTML. Here is an example:

<p>Short URL: <span id="short-url"></span></p>
<script>
  const originalUrl = "https://example.com/example 123.txt";
  const url = new URL(originalUrl);
  const shortUrl = url.pathname.replace(/ /g, "").split(".").slice(0, -1).join(".");
  document.getElementById("short-url").innerHTML = shortUrl;
</script>

In this example, we use the innerHTML property to set the text content of the span element to the short URL.

Conclusion

Displaying short versions of URLs can be challenging when dealing with files in a source tree that have math and spaces in their names. However, by using the URL object in JavaScript, you can create a short URL and display it in your application. This approach provides a flexible and efficient way to display short URLs in your application.
