Google login without fire base in react native

Introduction:

Google login without fire base in react native , Google login integration is a common requirement in mobile app development. While Firebase offers a convenient way to implement Google authentication in React Native, not everyone wants to use Firebase for various reasons, such as wanting more control or avoiding vendor lock-in. Google login without fire base in react native , In this guide, we’ll walk you through the process of implementing Google login in React Native without Firebase.

Google login without fire base in react native

Prerequisites:

Before we get started, make sure you have the following prerequisites in place:

  1. Node.js and npm installed on your development machine.
  2. A React Native project already set up.
  3. A Google Developer Console project with OAuth 2.0 credentials (Client ID and Client Secret).

Step 1: Install Dependencies and Google login without fire base in react native

how to Google login without fire base in react native ,To begin, you’ll need to install a few dependencies for handling OAuth 2.0 and user authentication in your React Native project. Open your terminal and navigate to your project folder. Run the following commands:

npm install axios react-native-google-signin react-native-google-signin/google-signin

Step 2: Configure OAuth 2.0 Credentials

how to Google login without fire base in react native , Go to the Google Developer Console (https://console.developers.google.com/) and create a new project or use an existing one. Follow these steps to set up OAuth 2.0 credentials:

  1. In the dashboard, click on “Create Project.”
  2. Once your project is created, navigate to the “Credentials” section on the left sidebar.
  3. Click on the “Create credentials” dropdown and select “OAuth client ID.”
  4. Choose “Web application” as the application type.
  5. In the “Authorized JavaScript origins” field, add your app’s URL (e.g., http://localhost:3000 for development).
  6. In the “Authorized redirect URIs” field, add the URI where you want Google to redirect after authentication (e.g., http://localhost:3000/auth/google/callback).
  7. Click “Create” to generate your OAuth client ID and client secret.

Step 3: Implement Google Login in React Native

Now, Google login without fire base in react native , let’s integrate Google login into your React Native app. Create a new JavaScript file (e.g., GoogleLogin.js) and follow this example code:

import React from ‘react’;
import { View, Button } from ‘react-native’;
import { GoogleSignin, GoogleSigninButton } from ‘react-native-google-signin’;

GoogleSignin.configure({
webClientId: ‘YOUR_WEB_CLIENT_ID’,
});

const GoogleLogin = ({ onLogin }) => {
const handleSignIn = async () => {
try {
await GoogleSignin.hasPlayServices();
const userInfo = await GoogleSignin.signIn();
onLogin(userInfo);
} catch (error) {
console.error(‘Google login error:’, error);
}
};

return (

);
};

export default GoogleLogin;

In this code:

  • Replace ‘YOUR_WEB_CLIENT_ID’ with your OAuth client ID obtained from the Google Developer Console.

Step 4: Integrate GoogleLogin Component

Now, you can integrate the Google Login component into your app’s login screen. Import it and use it like any other component:

import React from ‘react’;
import { View, Text } from ‘react-native’;
import GoogleLogin from ‘./GoogleLogin’;

const LoginScreen = () => {
const handleGoogleLogin = (userInfo) => {
// Handle user authentication and data storage here
console.log(‘Google user info:’, userInfo);
};

return (
Login with Google
);
};

export default LoginScreen;

Conclusion:

Congratulations! You’ve successfully implemented Google login in your React Native app without using Firebase. This approach gives you more control over the authentication process and allows you to customize it according to your project’s requirements. Make sure to handle user authentication and data storage securely in your app after obtaining user information from Google.

FAQs:

  1. Can I use this method for other social logins besides Google?
    • Yes, you can adapt a similar approach for other social logins by integrating their respective SDKs.
  2. Is Firebase authentication not recommended?
    • Firebase authentication is a robust solution, but some developers prefer more control over their authentication process.
  3. What security measures should I implement for user data?
    • Ensure that user data is stored securely and follow best practices for data protection.
  4. Can I use this in both Android and iOS apps?
    • Yes, this method works for both Android and iOS React Native apps.
  5. Are there any limitations to using OAuth 2.0 for authentication?
    • OAuth 2.0 is a widely accepted standard, but it’s essential to handle tokens securely to prevent unauthorized access.
