• Node 18.0.0 or higher

[!IMPORTANT]
To use Google Sign-In Button you need to install React Native version v0.78.0 or higher.

bun add react-native-nitro-google-sso react-native-nitro-modules
# or
npm install react-native-nitro-google-sso
# or
yarn add react-native-nitro-google-sso

Prerequisites

Before using this module, you need to:

1. Set up a Google Cloud Project
2. Configure OAuth 2.0 credentials
3. Get your iOS Client ID and Web Client ID from the Google Cloud Console

Configuration

First, you need to configure the module with your Google credentials. It's recommended to do this in your app's entry point:

import NitroGoogleSSO from 'react-native-nitro-google-sso'

// Configure the module
NitroGoogleSSO.configure({
  iosClientId: 'YOUR_IOS_CLIENT_ID',
  webClientId: 'YOUR_WEB_CLIENT_ID',
  nonce: 'YOUR_NONCE', // Optional security nonce
})

Usage

Sign In

To sign in with Google:

try {
  const user = await NitroGoogleSSO.signIn()
  if (user) {
    console.log('User signed in:', user)
  } else {
    console.log('User cancelled sign in')
  }
} catch (error) {
  console.error('Sign in error:', error)
}

One Tap Sign In

To sign in with Google using the one tap sign in:

try {
  const user = await NitroGoogleSSO.oneTapSignIn()
  if (user) {
    console.log('User signed in:', user)
  } else {
    console.log('User cancelled sign in')
  }
} catch (error) {
  console.error('Sign in error:', error)
}

Get Current User

To get the currently signed-in user's information:

try {
  const user = await NitroGoogleSSO.getCurrentUser()
  if (user) {
    console.log('Current user:', user)
  } else {
    console.log('No user is signed in')
  }
} catch (error) {
  console.error('Error getting current user:', error)
}

Sign Out

To sign out the current user:

try {
  await NitroGoogleSSO.signOut()
  console.log('User signed out successfully')
} catch (error) {
  console.error('Sign out error:', error)
}

Types

NitroGoogleSSOConfig

interface NitroGoogleSSOConfig {
  iosClientId: string
  webClientId: string
  nonce?: string
  hostedDomain?: string
}

NitroGoogleUserInfo

The user information returned by the sign-in process. The exact structure depends on the information requested during the sign-in process.

Platform Support

This module supports both iOS and Android platforms.

Error Handling

Always wrap the module's methods in try-catch blocks as they may throw errors in various scenarios:

• Network connectivity issues
• Invalid configuration
• User cancellation
• Authentication failures

Best Practices

1. Configure the module as early as possible in your app's lifecycle
2. Handle all potential errors appropriately
3. Implement proper state management for the user's authentication status
4. Store sensitive credentials securely
5. Implement proper error recovery mechanisms
