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
import React from 'react'
import { GoogleMap, useJsApiLoader } from '@react-google-maps/api';
const containerStyle = {
width: '400px',
height: '400px'
};
const center = {
lat: -3.745,
lng: -38.523
};
function MyComponent() {
const { isLoaded } = useJsApiLoader({
id: 'google-map-script',
googleMapsApiKey: "YOUR_API_KEY"
})
const [map, setMap] = React.useState(null)
const onLoad = React.useCallback(function callback(map) {
// This is just an example of getting and using the map instance!!! don't just blindly copy!
const bounds = new window.google.maps.LatLngBounds(center);
map.fitBounds(bounds);
setMap(map)
}, [])
const onUnmount = React.useCallback(function callback(map) {
setMap(null)
}, [])
return isLoaded ? (
<GoogleMap
mapContainerStyle={containerStyle}
center={center}
zoom={10}
onLoad={onLoad}
onUnmount={onUnmount}
>
{ /* Child components, such as markers, info windows, etc. */ }
<></>
</GoogleMap>
) : <></>
}
export default React.memo(MyComponent)
Migration from [email protected]
if you need an access to map object, instead of ref
prop, you need to use onLoad
callback on <GoogleMap />
component.
Before:
// before - don't do this!
<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
}}
/>
If you want to use window.google
object, you need to extract GoogleMap in separate module, so it is lazy executed then google-maps-api
script is loaded and executed by <LoadScript />
. If you try to use window.google
before it is loaded it will be undefined and you'll get a TypeError.
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:
- Official docs (powered by react-styleguidist.
- A Gatsby app including some examples. See the examples folder
- 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!
- In the file
packages/react-google-maps-api/package.json
changemain
to"src/index.ts"
- In the same file, delete the
module
field - 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 [email protected] and later versions.
