So, with that, now lets begin with how professional ReactJS developers integrate Google Maps in React.

How to Integrate Google Maps in React?

Once you have the prerequisite ready, the process of integrating Google Maps in React gets simple. Here is a stepwise process you can follow:

Step 1: Obtain an API Key

Visit the Google Cloud Console, create a new React project or select an existing one. Then navigate to APIs & Services > Library and search for Maps JavaScript API and enable it. After that go to APIs & Services > Credentials and create an API key. This key will be used to authenticate your application when accessing Google Maps services.

Step 2: Create a React App

If you don’t already have a React app, create one using the following command:

npx create-react-app google-maps-react
cd google-maps-react

Step 3: Install the Required Library

Open your terminal and run the following command to install the @react-google-maps/api library. It will provide you with a convenient way to use Google Maps in React.

npm install @react-google-maps/api

Step 4: Set Up the Google Maps Component

Create a component that will display the Google Map. Inside your src folder, create a file called MapComponent.js and add the following code:

import React from 'react';
import { GoogleMap, LoadScript } from '@react-google-maps/api';
const MapComponent = () => {
  const mapStyles = {
    height: "100vh",
    width: "100%"
  };
  const defaultCenter = {
    lat: 40.712776, // Latitude of default location (New York)
    lng: -74.005974 // Longitude of default location
  };

  return (
    <LoadScript googleMapsApiKey="YOUR_GOOGLE_MAPS_API_KEY">
      <GoogleMap
        mapContainerStyle={mapStyles}
        zoom={10}
        center={defaultCenter}
      />
    </LoadScript>
  )
}
export default MapComponent;

Explanation:

• LoadScript component ensures that the Google Maps script is loaded before rendering the map.
• GoogleMap is the component that renders the map, which takes properties like mapContainerStyle, zoom, and center.

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

Step 5: Integrate the Map into the Main Website

Now, import the MapComponent into your main app (App.js) and render it:

import React from 'react';
import './App.css';
import MapComponent from './MapComponent';

function App() {
  return (
    <div className="App">
      <h1>Google Maps in React</h1>
      <MapComponent />
    </div>
  );
}
export default App;

Step 6: Add Custom Markers

To enhance your map by adding markers, update the MapComponent.js file like so:

import React from 'react';
import { GoogleMap, LoadScript, Marker } from '@react-google-maps/api';

const MapComponent = () => {
  const mapStyles = {
    height: "100vh",
    width: "100%"
  };
  const defaultCenter = {
    lat: 40.712776,
    lng: -74.005974
  };

  const locations = [
    {
      name: "Location 1",
      location: { 
        lat: 40.712776, 
        lng: -74.005974 
      }
    },
    {
      name: "Location 2",
      location: { 
        lat: 40.730610, 
        lng: -73.935242 
      }
    }
  ];

  return (
    <LoadScript googleMapsApiKey="YOUR_GOOGLE_MAPS_API_KEY">
      <GoogleMap
        mapContainerStyle={mapStyles}
        zoom={10}
        center={defaultCenter}
      >
        {locations.map((item, index) => (
          <Marker key={index} position={item.location} />
        ))}
      </GoogleMap>
    </LoadScript>
  )
}
export default MapComponent;

Here, the Marker component is used to display a marker at specific coordinates. You can pass custom locations or use a list of coordinates as in the above example.

Step 7: Handling Map Events

You can handle different events like clicking on the map or dragging the markers. For instance, to add a click event, modify the GoogleMap component like this:

const onMapClick = (event) => {
  console.log("Clicked coordinates: ", event.latLng.lat(), event.latLng.lng());
};
return (
  <LoadScript googleMapsApiKey="YOUR_GOOGLE_MAPS_API_KEY">
    <GoogleMap
      mapContainerStyle={mapStyles}
      zoom={10}
      center={defaultCenter}
      onClick={onMapClick}
    >
      {/* Add markers or other components */}
    </GoogleMap>
  </LoadScript>
)

The onClick event will capture the latitude and longitude of the clicked point on the map.

Step 8: Customize Map Styles

You can apply custom styles to the Google Map. First, define a styles array and pass it to the options prop of GoogleMap:

const mapStyles = [
  {
    "elementType": "geometry",
    "stylers": [{ "color": "#ebe3cd" }]
  },
  {
    "elementType": "labels.text.fill",
    "stylers": [{ "color": "#523735" }]
  }

  // Add more styles as needed
];

return (
  <GoogleMap
    mapContainerStyle={mapContainerStyles}
    zoom={10}
    center={defaultCenter}
    options={{ styles: mapStyles }}
  >
    {/* Components */}
  </GoogleMap>
);

Google Maps also supports a variety of styles to change the appearance of roads, water, landscape, etc.

Step 9: Test Your Integration

Run your application to see the Google Map in action. Use the following command:

npm start

You should now see a Google Map rendered with a marker at the specified coordinates.

Step 10: Deploy Your React App

Once your map is integrated and working, you can deploy the React app to platforms like Netlify, Vercel, or GitHub Pages for public access.

With that, we have integrated Google Maps in React. If you are finding it hard to integrate or customize your site further, get in touch with ReactJS development company.
