@react-google-maps/api

What is @react-google-maps/api?

@react-google-maps/api is a library that provides a set of React components for integrating Google Maps into your React applications. It offers a simple and efficient way to use Google Maps features such as markers, info windows, and various map controls.

What are @react-google-maps/api's main functionalities?

Basic Map

This code demonstrates how to render a basic Google Map using the @react-google-maps/api package. The map is centered at a specific latitude and longitude and has a defined container style.

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

const containerStyle = {
  width: '400px',
  height: '400px'
};

const center = {
  lat: -3.745,
  lng: -38.523
};

function MyComponent() {
  return (
    <LoadScript googleMapsApiKey="YOUR_API_KEY">
      <GoogleMap
        mapContainerStyle={containerStyle}
        center={center}
        zoom={10}
      >
        { /* Child components, such as markers, info windows, etc. */ }
        <></>
      </GoogleMap>
    </LoadScript>
  )
}

export default MyComponent;

Markers

This code demonstrates how to add a marker to the Google Map. The marker is positioned at the center of the map.

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

const containerStyle = {
  width: '400px',
  height: '400px'
};

const center = {
  lat: -3.745,
  lng: -38.523
};

function MyComponent() {
  return (
    <LoadScript googleMapsApiKey="YOUR_API_KEY">
      <GoogleMap
        mapContainerStyle={containerStyle}
        center={center}
        zoom={10}
      >
        <Marker position={center} />
      </GoogleMap>
    </LoadScript>
  )
}

export default MyComponent;

Info Windows

This code demonstrates how to add an Info Window to a marker on the Google Map. The Info Window appears when the marker is clicked and can be closed by clicking the close button.

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

const containerStyle = {
  width: '400px',
  height: '400px'
};

const center = {
  lat: -3.745,
  lng: -38.523
};

function MyComponent() {
  const [selected, setSelected] = useState(null);

  return (
    <LoadScript googleMapsApiKey="YOUR_API_KEY">
      <GoogleMap
        mapContainerStyle={containerStyle}
        center={center}
        zoom={10}
      >
        <Marker
          position={center}
          onClick={() => setSelected(center)}
        />
        {selected && (
          <InfoWindow
            position={center}
            onCloseClick={() => setSelected(null)}
          >
            <div>
              <h2>Info Window</h2>
              <p>Details about this location.</p>
            </div>
          </InfoWindow>
        )}
      </GoogleMap>
    </LoadScript>
  )
}

export default MyComponent;

Other packages similar to @react-google-maps/api

google-maps-react

google-maps-react is another popular library for integrating Google Maps into React applications. It provides a set of React components similar to @react-google-maps/api but is considered less performant and less actively maintained.

react-google-maps

react-google-maps is an older library for Google Maps integration in React. It offers similar functionalities but is no longer actively maintained, and users are encouraged to migrate to @react-google-maps/api for better performance and support.

react-map-gl

react-map-gl is a library for integrating Mapbox maps into React applications. While it does not use Google Maps, it offers similar functionalities for map rendering, markers, and controls, making it a good alternative for those who prefer Mapbox.

@react-google-maps/api

@react-google-maps/api

This library requires React v16.6 or later. To use the latest features (including hooks) requires React v16.8+. If you need support for earlier versions of React, you should check out react-google-maps

This is complete re-write of the (sadly unmaintained) react-google-maps library. We thank tomchentw for his great work that made possible.

@react-google-maps/api provides very simple bindings to the google maps api and lets you use it in your app as React components.

Here are the main additions to react-google-maps that were the motivation behind this re-write

Install @react-google-maps/api

with NPM

npm i -S @react-google-maps/api

or Yarn

yarn add @react-google-maps/api

Migration from react-google-maps@9.4.5

if you need an access to map object, instead of ref prop, you need to use onLoad callback on <GoogleMap /> component.

Before:

// before
<GoogleMap
  ref={map => {
    const bounds = new window.google.maps.LatLngBounds();

    map.fitBounds(bounds);
  }}
/>

After:

<GoogleMap
  onLoad={map => {
    const bounds = new window.google.maps.LatLngBounds();
    map.fitBounds(bounds);
  }}
  onUnmount={map => {
    // do your stuff before map is unmounted
  }}
/>

Main features

• Simplified API
• Uses the new Context API
• Supports async React (StrictMode compliant)
• Removes lodash dependency => smaller bundle size 12.4kb gzip, tree-shakeable https://bundlephobia.com/result?p=@react-google-maps/api
• forbids loading of Roboto fonts, if you set property preventGoogleFonts on <LoadScript preventGoogleFonts /> component

Examples

Examples can be found in two places:

1. Official docs (powered by react-styleguidist.
2. A Gatsby app including some examples. See the examples folder
3. Gatsby.js Demo

Advice

Using the examples requires you to generate a google maps api key. For instructions on how to do that please see the following guide

How to test changes locally

When working on a feature/fix, you're probably gonna want to test your changes. This workflow is a work in progress. Please feel free to improve it!

1. In the file packages/react-google-maps-api/package.json change main to "src/index.ts"
2. In the same file, delete the module field
3. You can now use the package react-google-maps-api-gatsby-example to test your changes. Just make sure you change the import from @react-google-maps/api to ../../../react-google-maps-api

Since 1.2.0 you can use onLoad and onMount props for each @react-google-maps/api component, ref does not contain API methods anymore.

Since version 1.2.2 We added useGoogleMap hook, which is working only with React@16.8.1 and later versions.
