# react-native-streetview [![npm version](https://img.shields.io/npm/v/react-native-streetview.svg?style=flat)](https://www.npmjs.com/package/react-native-streetview)

Google's StreetView component for React Native  
(iOS and Android supported; **Expo** is supported — see [Expo](#expo) below)

## Features

- 🌐 Cross-platform Google Street View integration (iOS & Android)
- 🎥 Customizable camera position and point of view (tilt, bearing, zoom)
- 👆 Gesture controls for user interaction
- 🔍 Configurable search radius to find nearby panoramas
- 🏞️ Outdoor-only panorama option
- 📊 Event callbacks for errors, location changes, and camera movements (POV)
- ✅ Compatible with React Native 0.79+ and Fabric architecture
- 📱 **Expo**: works with development builds and `expo prebuild` (native Google Maps / Street View setup still applies)

## Preview

## Installation

```sh
yarn add react-native-streetview
# or using npm
npm install --save react-native-streetview
```

### Expo

This library ships native iOS and Android code, so use it with an [Expo development build](https://docs.expo.dev/develop/development-builds/introduction/) or a project using [`expo prebuild`](https://docs.expo.dev/workflow/prebuild/) (not Expo Go). Install the package as above, then configure your Google Maps API keys the same way as in the [iOS](#ios) and [Android](#android) sections (e.g. `app.json` / `app.config.js` plugins or config that set the native keys, depending on your setup).

### API Key Setup
1. Generate an API Key at https://console.developers.google.com/apis/credentials
2. Make sure Google Maps API is enabled in the Google Cloud Console

### iOS

1. Install GoogleMaps SDK for iOS using CocoaPods:
   - Add to your Podfile: `pod 'GoogleMaps'`
   - Run `pod install`
   - For detailed instructions, see: https://developers.google.com/maps/documentation/ios-sdk/config

2. Add your API key to AppDelegate:

```swift
import GoogleMaps

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    GMSServices.provideAPIKey("YOUR-API-KEY")
    // ...existing code...
    return true
}
```

### Android

1. Install Google Play services:
   - Open Android Studio's SDK Manager
   - Select and install "Google Play Services" from the SDK Tools tab
   - For detailed instructions, see: https://developers.google.com/maps/documentation/android-sdk/start

2. Add the API key to your app's Manifest file (`android\app\src\main\AndroidManifest.xml`):

```xml
   <application>
     
     <meta-data
       android:name="com.google.android.geo.API_KEY"
       android:value="YOUR-API-KEY"/>
   </application>
   ```

## Usage

### Basic Implementation

```javascript
import StreetView from 'react-native-streetview';
import { View, StyleSheet } from 'react-native';

const YourComponent = () => (
  <View style={styles.container}>
    <StreetView
      style={styles.streetView}
      allGesturesEnabled={true}
      coordinate={{
        latitude: 37.7749,
        longitude: -122.4194,
        radius: 50  // Search radius in meters
      }}
    />
  </View>
);
```

<summary><b>With Camera Position (POV)</b></summary>

```javascript
<StreetView

    longitude: -122.4194,
    radius: 50
  }}
  pov={{
    tilt: 30,     // Camera tilt angle in degrees (range: 0-90)
    bearing: 90,  // Camera compass direction (range: 0-360, where 0=North, 90=East)
    zoom: 1       // Camera zoom level (range: 0-5)
  }}
/>

<summary><b>Handling Events</b></summary>

```javascript
<StreetView
  style={styles.streetView}
  coordinate={{
    latitude: 37.7749,

  onError={(errorEvent) => {
    // Access detailed error information
    const errorData = errorEvent.nativeEvent;
    console.log('Street View error:', errorData.message);
    // Access additional context for debugging
    if (errorData.outdoorOnly) {
      console.log('Try disabling outdoorOnly or increasing radius');
    }
    // For advanced debugging:
    console.log('Error details:', {
      location: `${errorData.latitude}, ${errorData.longitude}`,
      radius: errorData.radius,
      outdoorOnly: errorData.outdoorOnly
    });
  }}
  onPanoramaChange={(event) => {
    // When user navigates to a new panorama location
    const { position } = event.nativeEvent;
    const { panoId } = event.nativeEvent;
    console.log('Panorama changed to new location:', {
      latitude: position.latitude,
      longitude: position.longitude
    });
    // On iOS, may include additional Street View metadata
    if (panoId) {
      console.log('Panorama ID:', panoId);
    }
  }}

    // When camera orientation changes
    const povData = event.nativeEvent;
    console.log('Camera view changed:');
    console.log('Bearing (direction):', povData.bearing);
    console.log('Tilt (angle):', povData.tilt);
    console.log('Zoom level:', povData.zoom);
    
    // * Only triggered when changes exceed threshold values
    // to avoid excessive updates during smooth camera movements
  }}

| `orientationGestures` | Boolean | `true` | Whether to enable panning gestures to change camera orientation |
| `zoomGestures` | Boolean | `true` | Whether to enable pinch gestures to zoom the camera |
| `navigationGestures` | Boolean | `true` | Whether to enable tap gestures to navigate between panoramas |

| `onPovChange` | Function | `null` | Callback when the Point of View (camera orientation) changes |

## Troubleshooting

### No panoramas found
- Ensure coordinates are in an area covered by Google Street View
- Try increasing the search radius
- Check if your API key has StreetView API enabled

### Black screen issues
- Verify your API key is correctly added to both platforms
- For React Navigation users, add margins to the StreetView component as mentioned in the usage notes
- Ensure the component has a proper size
