How to get the full URL in Express?

How to Get the Full URL in Express 🌐

Are you struggling with getting the full URL in your Express application? 🤔 Don't worry, you're not alone! Many developers face this common issue, and we're here to help you find an easy solution! 💪

Understanding the Problem 🤷‍♀️

Let's take a look at an example to understand the problem better. Imagine you have the following URL:

http://example.com/one/two

And you have a route defined in your Express application like this:

app.get('/one/two', function(req, res) {
    var url = req.url;
});

In this scenario, the value of url will be /one/two. But what if you want to get the full URL instead, like http://example.com/one/two? 🤔 That's where things get interesting!

Easy Solutions ✅

To get the full URL in Express, you can combine the req.protocol, req.hostname, and req.originalUrl properties. Here's how you can do it:

app.get('/one/two', function(req, res) {
    var fullURL = `${req.protocol}://${req.hostname}${req.originalUrl}`;
});

Let's break it down to understand what each property does:

• req.protocol: This property returns the protocol used in the request (e.g., http or https).

• req.hostname: This property returns the hostname of the requested URL (e.g., example.com).

• req.originalUrl: This property returns the original URL requested by the user (e.g., /one/two).

By combining these properties, you can create a string that represents the full URL of the current request! 🚀
