# React-Native

## Installation

<Steps>
### Install dependencies

We're dependent on `expo-application` for `buildNumber`, `versionNumber` (and `referrer` on android) and `expo-constants` to get the `user-agent`.

```bash
npm install @openpanel/react-native
npx expo install expo-application expo-constants
```

### Initialize

On native we use a clientSecret to authenticate the app.

```typescript
const op = new Openpanel({
  clientId: '{YOUR_CLIENT_ID}',
  clientSecret: '{YOUR_CLIENT_SECRET}',
});
```

#### Options

<CommonSdkConfig />
</Steps>

## Usage

### Track event

```typescript
op.track('my_event', { foo: 'bar' });
```

### Navigation / Screen views

<Tabs items={['expo-router', 'react-navigation (simple)']}>
  <Tabs.Tab>
    ```typescript
    import { usePathname, useSegments } from 'expo-router';

    function RootLayout() {
      // ...
      const pathname = usePathname()
      // Segments is optional but can be nice to have if you
      // want to group routes together
      // pathname = /posts/123
      // segements = ['posts', '[id]']
      const segments = useSegments()

      useEffect(() => {
        // Simple
        op.screenView(pathname)

        // With extra data
        op.screenView(pathname, {
          // segments is optional but nice to have
          segments: segments.join('/'),
          // other optional data you want to send with the screen view
        })
      }, [pathname,segments])
      // ...
    }
    ```

  </Tabs.Tab>
  <Tabs.Tab>
    ```tsx
      import { createNavigationContainerRef } from '@react-navigation/native'
      import { Openpanel } from '@openpanel/react-native'

      const op = new Openpanel({ /* ... */ })
      const navigationRef = createNavigationContainerRef()

      export function NavigationRoot() {
        const handleNavigationStateChange = () => {
          const current = navigationRef.getCurrentRoute()
          if (current) {
            op.screenView(current.name, {
              params: current.params,
            })
          }
        }

        return (
          <NavigationContainer
            ref={navigationRef}
            onReady={handleNavigationStateChange}
            onStateChange={handleNavigationStateChange}
          >
            <Stack.Navigator />
          </NavigationContainer>
        )
      }
    ```

  </Tabs.Tab>
</Tabs>
