npm package: @humanoids/react-native-recaptcha
Description: React native component to use the invisible recaptcha v3 from Google. Forked from @haskkor/react-native-recaptchav3.
Author: Jeremy Farnault
Latest version: 1.2.3

# @humanoids/react-native-recaptcha

This package is forked from `@haskkor/react-native-recaptchav3`. Refreshing the reCAPTCHA v3 token caused the following error:

```
Error evaluating injectedJavaScript: This is possibly due to an unsupported return type. Try adding true to the end of your injectedJavaScript string.
```

Also, `originWhitelist` needed to be specified. Fixes for these two issues have been applied.

Below you will find the original README with updated code snippets.

## Usage

Automatically get a captcha token:

```
import ReCaptchaV3 from '@humanoids/react-native-recaptcha'

<ReCaptchaV3
  captchaDomain={'https://yourowndomainname.co.nz'}
  siteKey={'yourownsitekey'}
  onReceiveToken={(token: string) => Alert.alert('CAPTCHA', token)}/>
```

One could also use a trigger to request a new token using the reference of the component:

```
import ReCaptchaV3 from '@humanoids/react-native-recaptcha'

<ReCaptchaV3
  ref={(ref: RecaptchaV3) => this._captchaRef = ref}
  captchaDomain={'https://yourowndomainname.co.nz'}
  siteKey={'yourownsitekey'}
  onReceiveToken={(token: string) => Alert.alert('CAPTCHA', token)}/>

<TouchableOpacity onPress={() => this._captchaRef.refreshToken()}>
  <Text>Retry</Text>
</TouchableOpacity>
```
