Display location on google map from address using javascript google map api

In today’s digital age, displaying locations on a map has become a crucial component of web applications. With the increasing popularity of location-based services, users expect to see their desired locations on maps, which makes it important for developers to integrate mapping functionality into their web applications.

One popular tool for displaying locations on maps is the Google Maps API, which provides developers with a set of tools to embed maps into their web applications. In this blog post, we will discuss how to use the Google Maps API to display a location on a map based on an address.

Step 1: Set Up the Google Maps API

Before you can use the Google Maps API, you need to set up an API key. To do this, follow these steps:

1. Go to the Google Cloud Console and create a new project.
2. Enable the Google Maps JavaScript API.
3. Create an API key.
4. Copy the API key for later use.

Step 2: Load the Google Maps API Library

Next, you need to load the Google Maps API library into your web application. To do this, add the following script tag to the head of your HTML file:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>

Replace YOUR_API_KEY with the API key you obtained in step 1.

Step 3: Get the Geocode of the Address

To display a location on a map, you need to obtain the latitude and longitude of the address. This process is called geocoding. The Google Maps API provides a geocoding service that you can use to obtain the latitude and longitude of an address.

To get the geocode of an address, you need to make an HTTP request to the geocoding service. The following code snippet shows how to make an HTTP request to the geocoding service:

const address = '1600 Amphitheatre Parkway, Mountain View, CA';
const url = `https://maps.googleapis.com/maps/api/geocode/json?address=${encodeURIComponent(address)}&key=${YOUR_API_KEY}`;

fetch(url)
  .then(response => response.json())
  .then(data => {
    const location = data.results[0].geometry.location;
    const lat = location.lat;
    const lng = location.lng;

    // display the map with the location
    initMap(lat, lng);
  });

Replace address with the address you want to geocode and YOUR_API_KEY with the API key you obtained in step 1.

Step 4: Display the Location on the Map

Finally, you can display the location on the map using the latitude and longitude obtained from the geocoding service. To do this, create a new google.maps.Map object and set the center property to the latitude and longitude of the location. Here’s an example of how to do this:

function initMap(lat, lng) {
  const map = new google.maps.Map(document.getElementById('map'), {
    center: { lat, lng },
    zoom: 8
  });
}

Replace map with the ID of the div element where you want to display the map, and zoom with the initial zoom level of the map.

In this blog post, we discussed how to display a location on a map using the Google Maps API. By following these simple steps, you can easily integrate mapping functionality into your web application and provide your users with a better user experience.
