Next.js Google Maps is a powerful combination that enhances web applications by offering interactive maps and location-based services. By integrating Google Maps into a Next.js application, developers can visually present geographical data, helping users navigate and explore locations effortlessly.
Next.js, a popular React framework, simplifies building server-side rendered applications with features like automatic code splitting and optimized performance. When combined with Google Maps, Next.js enables developers to create dynamic, responsive applications that leverage the rich functionality of the Google Maps API.
In this blog post, we’ll walk through the steps to integrate Next.js Google Maps effectively. You’ll learn to obtain and secure API keys, render the map within a React component, and add a default marker to enhance interactivity. Whether building a travel app, a location-based service or simply displaying geographical data, this guide will help you get started.

To use Next.js Google Maps, you first need to obtain an API key to access Google Maps services.
Steps to Get Your API Key:
➡️ Go to the Google Cloud Console:
• Navigate to Google Cloud Console.
➡️ Create a New Project:
• Click on the project drop-down and select “New Project.”
• Name your project and click “Create.”
➡️ Enable the Maps JavaScript API:
• In the navigation menu, go to APIs & Services > Library.
• Search for “Maps JavaScript API” and enable it for your project.
➡️ Get Your API Key:
• Navigate to APIs & Services > Credentials.
• Click on “Create credentials” and select “API key.”
• Copy the generated API key.
➡️ Restrict Your API Key (optional but recommended):
• Click on the created API key and set restrictions based on your needs (HTTP referrers, IP addresses, etc.).
➡️ Storing Your API Key:
• For security reasons, it’s best to store your API key in an environment variable. Create a .env.local file in the root of your Next.js project and add your key:
NEXT_PUBLIC_GOOGLE_MAPS_API_KEY=your_api_key_hereTo render Google Maps in your Next.js application, use the @react-google-maps/api library, which simplifies the process of implementing Next.js Google Maps.
➡️ Installation
First, install the required package:
npm install @react-google-maps/api➡️ Creating the Map Component
Create a new component called Map.js:
// components/Map.js
import React from 'react';
import { GoogleMap, LoadScript } from '@react-google-maps/api';
const mapContainerStyle = {
height: "400px",
width: "100%"
};
const center = {
lat: 37.7749, // Example: San Francisco
lng: -122.4194
};
const Map = () => {
return (
<LoadScript googleMapsApiKey={process.env.NEXT_PUBLIC_GOOGLE_MAPS_API_KEY}>
<GoogleMap
mapContainerStyle={mapContainerStyle}
center={center}
zoom={10}
>
{/* Additional components like markers can be added here */}
</GoogleMap>
</LoadScript>
);
};
export default Map;➡️ Using the Map Component
Now, you can use the Map component in your pages:
// pages/index.js
import React from 'react';
import Map from '../components/Map';
const Home = () => {
return (
<div>
<h1>My Google Map</h1>
<Map />
</div>
);
};
export default Home;Enhance your Next.js Google Maps implementation by adding a marker to indicate a specific location.
Updating the Map Component, modify your Map.js to include a marker:
// components/Map.js
import React from 'react';
import { GoogleMap, LoadScript, Marker } from '@react-google-maps/api';
const mapContainerStyle = {
height: "400px",
width: "100%"
};
const center = {
lat: 37.7749,
lng: -122.4194
};
const markerPosition = {
lat: 37.7749,
lng: -122.4194
};
const Map = () => {
return (
<LoadScript googleMapsApiKey={process.env.NEXT_PUBLIC_GOOGLE_MAPS_API_KEY}>
<GoogleMap
mapContainerStyle={mapContainerStyle}
center={center}
zoom={10}
>
<Marker position={markerPosition} />
</GoogleMap>
</LoadScript>
);
};
export default Map;
This guide has demonstrated how to integrate Next.js Google Maps into your application by obtaining and securing an API key, rendering the map, and adding a default marker. The integration of Google Maps with Next.js unlocks valuable features, enhancing user experience with location-based interactivity.
Feel free to extend your implementation by adding multiple markers, event listeners, or advanced features. By mastering Next.js Google Maps, you can build robust applications that engage users with seamless geographical data visualization.
