How to Get User’s Current Address Using JavaScript

In today’s digital age, location-based services have become integral to many web applications. Whether it’s for delivery tracking, social networking, or personalized content, knowing a user’s current location can greatly enhance the user experience. JavaScript, coupled with Google’s Geocoding service, provides a powerful means to retrieve accurate location information effortlessly. In this tutorial, we’ll delve into how you can harness this capability to fetch a user’s current address using JavaScript.

Understanding Geocoding:

Geocoding is the process of converting addresses (like “1500 Amphitheatre Parkway, Mountain View, CA”) into geographic coordinates (like latitude 35.423021 and longitude -120.083739), which you can use to place markers on a map or position the map. Google’s Geocoding API is a widely used service that provides accurate geocoding results.

Scenario:

    1. Imagine you’re developing an e-commerce website for a local bakery that offers online ordering and delivery services. As part of the checkout process, you want to provide customers with the option to have their order delivered to their current location automatically. To achieve this, you decide to implement a feature that retrieves the user’s current address using geolocation.
    2. You are developing a plugin or page for your stores that displays stores with markers on Google Maps and you want to add a button along with each store that allows you to generate directions between your current address to the store’s address then you need this function.

To solve this problem, Here I am going to add a simple script and you can it in your project.

Step 1: Setting Up Google Maps API Key
To begin, you need to obtain an API key from Google Cloud Platform Console. This key will authenticate your requests to the Geocoding API. Follow Google’s documentation to generate your API key.

Step 2: Implementing JavaScript Code
Once you have your API key, it’s time to write some JavaScript code. First, create an HTML file and include a script tag to load the Google Maps JavaScript API asynchronously. Then, add your JavaScript code to fetch the current address.

<!DOCTYPE html>
<html>
<head>
    <title>Get Current Address</title>
    <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" async defer></script>
</head>
<body>
    <div id="address"></div>
    <script>
        function initMap() {
            if (navigator.geolocation) {
                navigator.geolocation.getCurrentPosition(function (position) {
                    var geocoder = new google.maps.Geocoder();
                    var latlng = {
                        lat: position.coords.latitude,
                        lng: position.coords.longitude
                    };
                    geocoder.geocode({
                        'location': latlng
                    }, function (results, status) {
                        if (status === 'OK') {
                            if (results[0]) {
                                document.getElementById('address').innerHTML = 'Current Address: ' + results[0].formatted_address;
                            } else {
                                alert('No results found');
                            }
                        } else {
                            alert('Geocoder failed due to: ' + status);
                        }
                    });
                });
            } else {
                alert('Geolocation is not supported by this browser.');
            }
        }
    </script>
</body>
</html>

Replace YOUR_API_KEY with your actual API key obtained from Google Cloud Platform Console.

Step 3: Testing Your Code Open the HTML file in a web browser that supports geolocation.  While testing it will prompt the permission and you need to allow and then you should see the current address displayed on the webpage.

Conclusion:
In this tutorial, we’ve explored how to leverage JavaScript and Google’s Geocoding service to retrieve a user’s current address. By following these steps, you can enhance the functionality of your web applications with location-based features, thereby improving the overall user experience. Experiment with different ways to utilize this capability and unlock the full potential of geolocation in your projects.
