Understanding the Problem: Retrieving the Base URL in Angular 8+

If you're working with Angular 8 or later, you might sometimes need to extract just the base URL of your application without the subsequent route. For instance, let's say you're on the page http://localhost:4200/recommendation. What if you only want to obtain http://localhost:4200? This can be particularly useful when you need to build dynamic links or simply log the base URL for debugging purposes.

The Common Confusion

You might wonder if you need to use a routing service or parse the URL string manually to achieve this. Fortunately, Angular and the underlying browser APIs provide a more elegant solution. Let's delve into the different ways you can retrieve your application's base URL without unnecessary complexity.

The Solution: Using window.location.origin

The best way to obtain your base URL is to use the window.location object, specifically the origin property. This property returns the protocol, hostname, and port of the current URL, giving you exactly what you're looking for.

Here's How to Do It

To get the base URL in your Angular application, simply use the following code:

Explanation of the Code

window: This is a global object that represents the browser window.

location: This property of the window object contains information about the current URL.

origin: This particular property fetches the base URL.

Example Usage

When you run the above line of code in your Angular application, you will see an output like this in the console:

Advantages of Using window.location.origin

Simplicity: It avoids the need for complex string manipulation.

Readability: The code is straightforward and easy for other developers to understand.

Efficiency: It includes both the protocol (HTTP or HTTPS) and the host, ensuring you don’t miss critical components of the base URL.

Contrast with Other Approaches

While it may be tempting to manually split the full URL string using methods like split(), this approach is error-prone and requires you to account for various scenarios (e.g., different ports, presence of different protocols). Using window.location.origin is a foolproof method that mitigates these risks effectively.

Conclusion

In summary, if you're looking to obtain the base URL of your Angular application in versions 8 and above, the best solution is to utilize the window.location.origin property. It offers a clean, efficient, and reliable way to extract just the information you need without dealing with unnecessary complexity. By integrating this simple line of code into your project, you can streamline your URL handling processes and enhance your application's functionality.
