# Google Maps React Hooks



[![npm version](https://img.shields.io/npm/v/@ubilabs/google-maps-react-hooks)](https://www.npmjs.com/package/@ubilabs/google-maps-react-hooks) [![GitHub license](https://img.shields.io/badge/license-MIT-green.svg)](./LICENSE)



## Description



This is a JavaScript library to easily implement a Google Maps map into your React application. It comes with a collection of React hooks to access the Google Maps map instance all over your components and to use some of the Google Maps [Services](https://developers.google.com/maps/documentation/javascript#services) or [Libraries](https://developers.google.com/maps/documentation/javascript#libraries).

## Requirements



You need to have React [16.8.0](https://reactjs.org/blog/2019/02/06/react-v16.8.0.html) or later installed to use the Hooks API.



## Installation



```sh

npm install @ubilabs/google-maps-react-hooks -D

```



**NOTE FOR WINDOWS USERS**:

We are using [cross-env](https://github.com/kentcdodds/cross-env) for environment variables to work on all platforms. There is an issue that `npm` uses `cmd` by default. The workaround is to add `script-shell` to `powershell` in your `.npmrc`. Please follow [this setup](https://github.com/kentcdodds/cross-env/issues/192#issuecomment-513341729) to make it work.



## Library



The full Google Maps React Hooks library can be found in the [library directory](./library).



## Basic Google Map Setup



Import the `GoogleMapsProvider` and wrap it around your components.

Make sure all components that should have access to the Google Maps map instance are nested inside the `GoogleMapsProvider`.



If you still can't see a map on your page, make sure that your map container has a `height` CSS property (by default it usually has no height) and that a `center` and `zoom` was set for your map.



```tsx

import React, {useState, useCallback, forwardRef} from 'react';

import {GoogleMapsProvider} from '@ubilabs/google-maps-react-hooks';



function App() {

  const [mapContainer, setMapContainer] = useState(null);

  const mapRef = useCallback(node => {

    node && setMapContainer(node);

  }, []);



  const mapOptions = {

    // Add your map options here

    // `center` and `zoom` are required for every map to be displayed

    center: {lat: 53.5582447, lng: 9.647645},

    zoom: 6

  };



  return (

    

      

        


      

    

  );

}



export default App;

```



The `GoogleMapsProvider` makes the Google Maps map instance available to any nested components with the `useGoogleMap` hook.



```tsx

import React from 'react';

import {useGoogleMap} from '@ubilabs/google-maps-react-hooks';



const MyComponent = () => {

  const map = useGoogleMap();



  // Do something with the Google Maps map instance



  return (...);

};

```



## Hooks



All hooks can be found [here](./library/src/hooks/). Please checkout the [documentation](./library/docs) for each hook and have a look at the [examples directory](./examples) to see how each hook can be implemented.



### Hooks Overview



- [useGoogleMap](./library/docs/useGoogleMap.md)

- [useDirectionsService](./library/docs/useDirectionsService.md)

- [useDistanceMatrixService](./library/docs/useDistanceMatrixService.md)

- [useElevationService](./library/docs/useElevationService.md)

- [useGeocodingService](./library/docs/useGeocodingService.md)

- [useMaxZoomService](./library/docs/useMaxZoomService.md)

- [usePlacesService](./library/docs/usePlacesService.md)

- [useAutocomplete](./library/docs/useAutocomplete.md)

- [useAutocompleteService](./library/docs/useAutocompleteService.md)



### Hooks Example Setup



**useGeocodingService**



```tsx

import React from 'react';

import {useGeocodingService} from '@ubilabs/google-maps-react-hooks';



const MyComponent = () => {

  const geocoder = useGeocodingService();



  // Do something with the geocoder



  return (...);

};

```



**useAutocomplete**



```tsx

import React, {useRef, useState} from 'react';

import {useAutocomplete} from '@ubilabs/google-maps-react-hooks';



const MyComponent = () => {

  const inputRef = useRef(null);

  const [inputValue, setInputValue] = useState('');



  const onPlaceChanged = place => {

    if (place) {

      setInputValue(place.formatted_address || place.name);

    }



    // Keep focus on input element

    inputRef.current && inputRef.current.focus();

  };



  useAutocomplete({

    inputField: inputRef && inputRef.current,

    onPlaceChanged

  });



  const handleInputChange = event => {

    setInputValue(event.target.value);

  };



  return (

    

  );

};

```
