React.js Google Maps API integration
npm install @byrekt/react-google-maps-api!logo
@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
with NPM
``#!/bin/bash`
npm i -S @react-google-maps/api
or Yarn
`#!/bin/bash`
yarn add @react-google-maps/api
`jsx
import React from 'react'
import { GoogleMap, LoadScript } from '@react-google-maps/api';
const containerStyle = {
width: '400px',
height: '400px'
};
const center = {
lat: -3.745,
lng: -38.523
};
function MyComponent() {
const [map, setMap] = React.useState(null)
const onLoad = React.useCallback(function callback(map) {
const bounds = new window.google.maps.LatLngBounds();
map.fitBounds(bounds);
setMap(map)
}, [])
const onUnmount = React.useCallback(function callback(map) {
setMap(null)
}, [])
return (
>
center={center}
zoom={10}
onLoad={onLoad}
onUnmount={onUnmount}
>
{ / Child components, such as markers, info windows, etc. / }
<>
)
}
export default React.memo(MyComponent)
`
if you need an access to map object, instead of ref prop, you need to use onLoad callback on component.
Before:
`jsx
// before - don't do that!
const bounds = new window.google.maps.LatLngBounds();
map.fitBounds(bounds);
}}
/>
`
After:
`jsx`
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 . If you try to use window.google before it is loaded it will be undefined and you'll get a TypeError.
- 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 component
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
> Using the examples requires you to generate a google maps api key. For instructions on how to do that please see the following guide

Maintainers and contributors are very welcome! See this issue to get started.
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 fieldreact-google-maps-api-gatsby-example
3. You can now use the package 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.
