Implement Google OAuth Authentication for LogiQuest

[onlydustapp]

📚 Overview

Implement Google OAuth authentication in LogiQuest to allow users to sign in with their Google accounts. This feature should leverage Passport.js and work seamlessly within the existing authentication flow.

🛠️ Tasks

1. Add Google OAuth Strategy

   • Implement a Google OAuth strategy using Passport.js
   • Create a GoogleStrategy provider
   • Configure authentication using environment variables (ensure documentation is updated)

2. Create Authentication Controller Endpoints

   • Add an endpoint to initiate Google authentication
   • Create a callback endpoint to handle Google's response
   • Implement user profile creation for new Google users

3. Update User Entity

   • Add a googleId field
   • Add a provider field (values: local/google)
   • Ensure proper updates to the database schema

4. JWT Generation for Google Auth

   • Generate JWT tokens after successful Google authentication
   • Ensure proper user data is included in the tokens

5. HTTPyac Test Files

   • Include HTTPyac test files to demonstrate the working implementation

### Initiate Google Auth (this will redirect to Google)
GET http://localhost:3000/auth/google

### Manually test the callback URL after authentication
GET http://localhost:3000/auth/google/callback?code=EXAMPLE_CODE

### Verify that the JWT token works by accessing a protected endpoint
GET http://localhost:3000/auth/profile
Authorization: Bearer {{google.response.body.access_token}}

🚨 Technical & Setup Considerations

• Use @nestjs/passport and passport-google-oauth20 packages
• Use environment variables for Google OAuth credentials (Client ID/Secret)
• IMPORTANT: Use npm ci instead of npm install when setting up the project to avoid dependency issues

✅ Acceptance Criteria

• Users can initiate authentication with Google
• Google authentication flow completes successfully
• New users are created on first Google login
• Existing users are properly linked with Google accounts
• JWT tokens are issued after successful authentication
• Error handling for failed authentication attempts
• Environment variables are documented for Google OAuth credentials

Let's ensure we follow the dependency guidelines and use the proper setup commands 😃

Hi there! I'd like to take on this Google OAuth implementation task. I have extensive experience with NestJS and Passport.js OAuth strategies, having successfully implemented similar authentication flows in previous projects. I'm familiar with JWT token handling and database schema migrations, which will be essential for this task. I estimate I can complete the full implementation within 7-9 hours, including thorough testing and documentation updates. Looking forward to enhancing LogiQuest with this important authentication feature!
