Angular Location Service – A Comprehensive Guide

Angular is a popular open-source web application framework designed specifically for building dynamic, single-page applications. One of the most important features of Angular is its Location Service, which offers developers an easy way to handle browser navigation, including go/back/forward buttons, as well as deep linking and other browser-related functionality.

In this article, we will explore the Angular Location Service in detail, discussing its uses, benefits, and common usage patterns. We will also provide code examples and answer frequently asked questions to help you get started with using this powerful tool in your own Angular projects.

What is the Angular Location Service?

The Angular Location Service is a built-in service that provides an Angular application with access to the browser’s URL routing and history management functionality. By using this service, you can easily manipulate the browser’s history and control what happens when the user clicks on the back or forward buttons, enters a new URL in the address bar, or reloads the page.

The Location Service is part of the Angular Router, which is responsible for managing the application state and routing requests to the correct components. By default, the Angular Router automatically subscribes to changes in the browser’s location and updates the application state accordingly. However, you can also use the Location Service directly to manipulate the browser’s location and history, bypassing the Angular Router if needed.

How to Use the Angular Location Service?

To use the Angular Location Service, you need to inject it into your component or service like this:

import { Location } from ‘@angular/common’;

constructor(private location: Location) { }

Once you have access to the Location object, you can start manipulating the browser’s location and history by calling its methods. Here are some common use cases:

1. Navigate to a new URL

To navigate to a new URL, you can use the `location.go()` method, which pushes a new entry onto the browser’s history stack and changes the current location. For example:


2. Navigate to the previous URL

To navigate to the previous URL, you can use the `location.back()` method, which simulates a click on the back button. For example:


3. Navigate to the next URL

To navigate to the next URL, you can use the `location.forward()` method, which simulates a click on the forward button. For example:


4. Get the current URL

To get the current URL, you can use the `location.path()` method, which returns the path portion of the URL. For example:

const currentUrl = this.location.path();

5. Listen for changes in the URL

To listen for changes in the URL, you can subscribe to the `locationChange` event emitter, which emits an event every time the URL changes. For example:

this.location.onUrlChange((url: string) => {
console.log(‘The URL has changed to: ‘, url);

Why Use the Angular Location Service?

The Angular Location Service is useful for a variety of reasons, including:

1. Deep linking: By using the Location Service, you can provide direct links to specific pages or content within your application, making it easier for users to share and bookmark your content.

2. History management: By controlling the browser’s history, you can provide a better user experience by enabling the use of back and forward buttons, preventing accidental page refreshes, and other common navigational issues.

3. Fine-grained control: By using the Location Service directly, you have greater control over how the application handles URL changes, which can be useful in complex or non-standard routing scenarios.


Q: Can I use the Location Service with other routing libraries?

A: Yes, the Location Service can be used with other routing libraries, such as React Router or Vue Router, as long as they provide a compatible API.

Q: How do I handle cases where the user enters an invalid URL?

A: You can use the Angular Router’s wildcard route to handle cases where the user enters an invalid URL. This can be done by adding a route with a path of ‘**’ to your routing configuration.

Q: Can I use the Location Service to prevent the user from leaving a page?

A: Yes, you can use the `window.onbeforeunload` event to intercept the user’s attempt to leave the page and display a dialog box asking them to confirm their action. However, this is generally considered bad UX and should be used sparingly.


The Angular Location Service is a powerful tool for managing browser navigation and history in an Angular application. By providing deep linking, history management, and fine-grained control over URL changes, the Location Service enables developers to create better user experiences and more complex routing scenarios. With the examples and FAQs provided in this article, you should now have a good understanding of how to use the Angular Location Service in your own projects.
