Integrating Google OAuth into the OpenClaw Full‑Stack Template

Integrating Google OAuth into the OpenClaw Full‑Stack Template

To add Google OAuth to the OpenClaw full‑stack template, create Google credentials, update the OpenClaw auth module with the new client ID and secret, modify the authentication code, and verify the flow with a local test run.

1. Introduction

OpenClaw is a ready‑made full‑stack starter that ships with a modular authentication system. By default it supports email/password login, but many modern applications require social sign‑in options such as Google OAuth. This tutorial walks full‑stack developers and DevOps engineers through the entire process— from generating Google OAuth credentials to testing the integration— using UBOS’s low‑code platform.

2. Prerequisites

• Running OpenClaw instance (hosted via OpenClaw hosting page)
• Node.js ≥ 16 and npm ≥ 8 installed locally
• Access to a Google Cloud project with the OAuth Consent Screen enabled
• Basic familiarity with Express.js and React (the front‑end framework used by OpenClaw)

3. Create Google OAuth credentials

Follow these steps in the Google Cloud Console:

1. Navigate to Google Cloud Credentials and click Create Credentials → OAuth client ID.
2. Choose Web application as the application type.
3. Enter a name (e.g., OpenClaw Google OAuth).
4. Under Authorized JavaScript origins, add your development URL, e.g., http://localhost:3000.
5. Under Authorized redirect URIs, add http://localhost:3000/auth/google/callback.
6. Click Create. Copy the generated Client ID and Client Secret—you’ll need them later.

Tip: Store the credentials in a .env file to keep them out of source control:

# .env
GOOGLE_CLIENT_ID=YOUR_CLIENT_ID_HERE
GOOGLE_CLIENT_SECRET=YOUR_CLIENT_SECRET_HERE

4. Configure OpenClaw auth module

OpenClaw’s authentication logic lives in /src/server/auth. To enable Google OAuth, you’ll add a new strategy using passport-google-oauth20.

4.1 Install required packages

npm install passport-google-oauth20 dotenv

4.2 Update auth/index.js

Add the Google strategy and expose routes for login and callback.

// src/server/auth/index.js
require('dotenv').config();
const passport = require('passport');
const GoogleStrategy = require('passport-google-oauth20').Strategy;
const User = require('../models/User'); // Adjust path if needed

passport.use(new GoogleStrategy({
    clientID: process.env.GOOGLE_CLIENT_ID,
    clientSecret: process.env.GOOGLE_CLIENT_SECRET,
    callbackURL: '/auth/google/callback',
}, async (accessToken, refreshToken, profile, done) => {
    try {
        // Find or create a user based on Google profile ID
        let user = await User.findOne({ googleId: profile.id });
        if (!user) {
            user = await User.create({
                googleId: profile.id,
                email: profile.emails[0].value,
                name: profile.displayName,
                avatar: profile.photos[0].value,
            });
        }
        return done(null, user);
    } catch (err) {
        return done(err, null);
    }
}));

// Serialize / deserialize
passport.serializeUser((user, done) => done(null, user.id));
passport.deserializeUser(async (id, done) => {
    const user = await User.findById(id);
    done(null, user);
});

module.exports = passport;

4.3 Register routes in server.js

// src/server/server.js
const express = require('express');
const session = require('express-session');
const passport = require('./auth'); // Path to the file above

const app = express();

app.use(session({
    secret: process.env.SESSION_SECRET || 'super-secret',
    resave: false,
    saveUninitialized: true,
}));
app.use(passport.initialize());
app.use(passport.session());

// Google OAuth routes
app.get('/auth/google',
    passport.authenticate('google', { scope: ['profile', 'email'] })
);

app.get('/auth/google/callback',
    passport.authenticate('google', { failureRedirect: '/login' }),
    (req, res) => {
        // Successful authentication, redirect home.
        res.redirect('/');
    }
);

// Existing routes …

5. Update authentication code (Front‑end)

The React UI in OpenClaw lives under /src/client. Add a “Sign in with Google” button that redirects to the new endpoint.

5.1 Create a Google button component

// src/client/components/GoogleLoginButton.jsx
import React from 'react';

const GoogleLoginButton = () => (
    <a
        href="/auth/google"
        className="inline-flex items-center px-4 py-2 bg-red-600 text-white rounded hover:bg-red-700 transition"
    >
        <svg className="w-5 h-5 mr-2" viewBox="0 0 48 48">
            <path fill="#EA4335" d="M24 9.5c3.5 0 6.6 1.2 9 3.2l6.7-6.7C36.5 2.5 30.6 0 24 0 14.7 0 6.6 5.2 2.5 12.9l7.9 6.1C12.5 13.5 17.8 9.5 24 9.5z"/>
            <path fill="#4285F4" d="M46.5 24c0-1.6-.1-3.2-.4-4.7H24v9h12.7c-.5 2.7-2 5-4.2 6.5l6.5 5c3.8-3.5 6-8.7 6-15.8z"/>
            <path fill="#FBBC05" d="M10.4 28.9c-.5-1.5-.8-3.2-.8-4.9s.3-3.4.8-4.9L2.5 12.9C.9 15.9 0 19.3 0 24c0 4.7.9 8.1 2.5 11.1l7.9-6.2z"/>
            <path fill="#34A853" d="M24 48c6.6 0 12.5-2.2 16.7-5.9l-6.5-5c-3.6 2.4-8.2 3.8-13.2 3.8-6.2 0-11.5-4-13.5-9.5l-7.9 6.1C6.6 42.8 14.7 48 24 48z"/>
            <path fill="none" d="M0 0h48v48H0z"/>
        </svg>
        Sign in with Google
    </a>
);

export default GoogleLoginButton;

5.2 Insert the button into the login page

// src/client/pages/Login.jsx
import GoogleLoginButton from '../components/GoogleLoginButton';

const Login = () => (
    <div className="max-w-md mx-auto mt-12 p-6 bg-white rounded shadow">
        <h2 className="text-2xl font-bold mb-4">Login</h2>
        {/* Existing email/password form */}
        <form>...</form>
        <div className="my-4 text-center">or</div>
        <GoogleLoginButton />
    </div>
);

export default Login;

After rebuilding the client (npm run build), the Google button appears alongside the traditional login form.

6. Test the integration

Run the development server and verify the OAuth flow:

1. Start the backend: npm run dev:server
2. Start the frontend: npm run dev:client
3. Open http://localhost:3000/login in a browser.
4. Click Sign in with Google. You should be redirected to Google’s consent screen.
5. After granting permission, you’ll be sent back to /auth/google/callback and then to the home page as an authenticated user.

To confirm the session, inspect the browser’s cookies for a connect.sid entry (or the session token you configured). You can also query the /api/me endpoint (if available) to see the returned user object.

7. Troubleshooting

For deeper debugging, enable Passport logging by setting DEBUG=passport:* before starting the server.

8. Conclusion

Integrating Google OAuth into the OpenClaw full‑stack template enhances user experience and reduces friction during sign‑up. By leveraging UBOS’s modular architecture, you can add the Google strategy in under 30 minutes, keep credentials secure with environment variables, and test the flow locally before deploying to production.

Once you’re comfortable with Google, the same pattern applies to other providers (GitHub, Microsoft, etc.)—just swap the Passport strategy and update the redirect URIs.
