# 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 (

);
};
```
