# react-native-google-play-install-referrer

Retrieve referral details on app install from Google Play.

The type of referral information we can get from Google Play by using [Google Play Install Referrer](https://developer.android.com/google/play/installreferrer):

- The referrer URL of the installed package.
- The timestamp, in seconds, of when a referrer click happened (both client- and server-side).
- The timestamp, in seconds, of when an installation began (both client- and server-side).
- The app's version at the time when the app was first installed.
- Whether the user has interacted with your app's instant experience in the past 7 days.

## Installation

```sh
npm install react-native-google-play-install-referrer
```

## Usage

```js
import useInstallReferrer from 'react-native-google-play-install-referrer';

export default function App() {
  const { isSuccess, isError, data, error } = useInstallReferrer();

  React.useEffect(() => {
    if (isSuccess)
      Alert.alert('Install Referrer Success', JSON.stringify(data));
    else if (isError) Alert.alert('Install Referrer Error', error);
  }, [isSuccess, isError, data, error]);
  return <></>;
}
```

```js
import { getReferrer } from 'react-native-google-play-install-referrer';

export default function App() {

  React.useEffect(() => {
    try {
      const referrer = await getReferrer()
    }
    catch (err) {
      console.log(err)
    }
  }, []);
  return <></>;
}
```
