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](https://github.com/tomchentw/react-google-maps) > Versions starting 12.20.0 should support React@19. This is complete re-write of the (sadly unmaintained) `react-google-maps` library. We thank [tomchentw](https://github.com/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 PNPM ```shell pnpm install @react-google-maps/api ``` with NPM ```shell npm i -S @react-google-maps/api ``` ```jsx 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 ? ( {/* Child components, such as markers, info windows, etc. */} <> ) : ( <> ) } export default React.memo(MyComponent) ``` ## 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 `` component. Before: ```jsx // before - don't do this! { 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. ## 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](https://bundlephobia.com/result?p=@react-google-maps/api) - forbids loading of Roboto fonts, if you set property preventGoogleFonts on `` component ## Examples Examples can be found in two places: 1. [Official docs](https://react-google-maps-api-docs.netlify.app/) (powered by [react-styleguidist](https://github.com/styleguidist/react-styleguidist). 2. A Gatsby app including some examples. See the [examples](https://github.com/JustFly1984/react-google-maps-api/tree/master/packages/react-google-maps-api-gatsby-example/src/examples) folder ## 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](https://developers.google.com/maps/documentation/embed/get-api-key) ## Community Help Resource You can join our [Slack channel](https://join.slack.com/t/react-google-maps-api/shared_invite/enQtODc5ODU1NTY5MzQ4LTBiNTYzZmY1YmVjYzJhZThkMGU0YzUwZjJkNGJmYjk4YjQyYjZhMDk2YThlZGEzNDc0M2RhNjBmMWE4ZTJiMjQ) ## Contribute Maintainers and contributors are very welcome! See [this issue](https://github.com/JustFly1984/react-google-maps-api/issues/18) to get started. ## 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.
