An Ultimate Guide to Get Domain from URL Using Javascript for Seamless Website Navigation
Get Domain From Url Javascript: A simple solution to extract domain name from a URL using JavaScript. Improve your web development skills today!
Are you tired of manually extracting domain names from URLs? Well, fear not my fellow developers, for I have the solution for you! With just a few lines of code in Javascript, you can easily retrieve domain names from any URL. But wait, there's more! This handy trick can also help you optimize your website's performance and improve user experience. So, sit back, relax, and let me show you how to get domain from URL in Javascript!
First things first, let's talk about why you would even need to extract domain names from URLs in the first place. Maybe you want to track where your website traffic is coming from, or you need to parse URLs in order to perform certain actions. Whatever the reason may be, it's a tedious task to manually extract domain names from each URL. That's where this Javascript trick comes in handy.
Now, let's dive into the code. The first step is to create a new URL object with the URL string as its parameter:
```const url = new URL('https://www.example.com/path/to/page.html');```Next, we can simply access the domain property of the URL object to retrieve the domain name:
```const domain = url.hostname;```And just like that, we have retrieved the domain name from the URL! But what if the URL doesn't include the protocol (i.e. http or https)? Don't worry, we can handle that too:
```const urlWithoutProtocol = 'www.example.com/path/to/page.html';const urlWithProtocol = `https://${urlWithoutProtocol}`;const url = new URL(urlWithProtocol);const domain = url.hostname;```By adding the protocol to the URL string before creating the URL object, we can ensure that the hostname property will always return the correct domain name.
But wait, there's one more thing we can do to make this even more efficient. Instead of creating a new URL object every time we need to retrieve a domain name, we can create a reusable function:
```function getDomainFromUrl(urlString) { const urlWithoutProtocol = urlString.replace(/(^\w+:|^)\/\//, ''); const urlWithProtocol = `https://${urlWithoutProtocol}`; const url = new URL(urlWithProtocol); return url.hostname;}```Now, we can simply call this function with any URL string as its parameter:
```const domain = getDomainFromUrl('www.example.com/path/to/page.html');```And voila! We have successfully retrieved the domain name from the URL without writing repetitive code.
But why stop there? With this trick, we can also improve our website's performance by preloading domain-specific assets. By extracting the domain name from the current URL, we can determine which assets to preload based on the user's location. This can greatly reduce load times and improve user experience.
In conclusion, getting domain from URL in Javascript doesn't have to be a daunting task. With just a few lines of code, you can easily extract domain names and improve your website's performance. So go forth, my fellow developers, and conquer those URLs!
Introduction
Well, well, well, what do we have here? Another article about getting domain from URL in Javascript? Boring! But wait, hold on a second. What if I told you that this article is going to be different? That it will make you chuckle and maybe even laugh out loud? Yes, my dear reader, that's exactly what's going to happen. So sit back, relax and get ready for some fun.
The Problem
Alright, let's get serious for a moment. We all know that getting the domain from a URL in Javascript can be a pain in the neck. Sure, there are libraries out there that can do it for you, but where's the fun in that? Plus, you don't want to add unnecessary weight to your code. So, what's the solution? A custom function, of course. But how do you go about creating one?
The Solution
First things first, let's break down the problem into smaller parts. We need to extract the protocol, hostname and port from the URL. Once we have those, we can concatenate them together to form the domain. Simple, right? Well, not really. There are a lot of edge cases to consider, like URLs without a protocol or with a default port. But fear not, my friend. We'll tackle them one by one.
The Protocol
Let's start with the protocol. This is the part of the URL that comes before the double slashes (e.g. https:// or ftp://). To extract it, we can use the built-in location.protocol property. However, this will also include the colon at the end, so we need to remove it using the slice method.
The Hostname
Next up, we have the hostname. This is the part of the URL that comes after the double slashes and before the first slash (e.g. www.example.com). To extract it, we can use the location.hostname property. However, this will also include the port number if there is one, so we need to remove it using the split method.
The Port
Finally, we have the port. This is the part of the URL that comes after the hostname and the colon (e.g. 8080). To extract it, we can use the location.port property. However, this will also include the colon at the beginning, so we need to remove it using the slice method. But what if there is no port number in the URL? In that case, we need to use the default port for the protocol (e.g. 80 for HTTP, 443 for HTTPS).
The Code
Now that we have all the pieces of the puzzle, let's put them together in a function:
```function getDomainFromUrl(url) { var protocol = location.protocol.slice(0, -1); var hostname = location.hostname.split(:)[0]; var port = location.port || (protocol === https ? 443 : 80); return protocol + :// + hostname + : + port;}```Conclusion
Voila! We now have a custom function that can get the domain from a URL in Javascript. Wasn't that fun? Okay, maybe not as fun as watching cat videos on YouTube, but still pretty cool. And the best part? You can impress your friends with your newfound knowledge. Just don't forget to credit me when you do. Happy coding!
