Objective

Implement OAuth2 authentication for users, allowing them to log in using their Google, Microsoft, Apple, and GitHub accounts. Integrate this with the existing Next.js project, MongoDB, and Prisma, and organize the files within an "auth" folder.

Steps to Achieve:

1. OAuth2 Setup:

   • Provider Apps: Create developer accounts on Google, Microsoft, Apple, and GitHub to obtain API keys and secrets for OAuth2.
   • Configure OAuth2: Set up OAuth2 configurations for each provider in your project.

2. Create Auth Folder:

   • Directory: Create a new folder named "auth" in the root of your project.
   • Structure: The "auth" folder will contain files related to authentication.

3. Install OAuth2 Libraries:

   • Dependencies: Install OAuth2 libraries for each provider (e.g., passport-google-oauth20, passport-microsoft, passport-apple, passport-github).

4. Configure OAuth2 Strategies:

   • Inside the "auth" folder: Create files (e.g., googleAuth.ts, microsoftAuth.ts, appleAuth.ts, githubAuth.ts) to configure OAuth2 strategies for each provider using Passport.js.

5. Update Backend API Routes:

   • Inside the "auth" folder: Update the API route files (e.g., login.ts and signup.ts) to handle OAuth2 authentication.
   • Controllers: Implement controller functions to handle OAuth2 authentication using the configured strategies.

6. Prisma Integration:

   • Prisma Models: Update your Prisma models to include fields for storing information obtained from OAuth2 providers.
   • Update Database: Modify the API route files to store user data retrieved from OAuth2 providers in the MongoDB database.

7. Frontend Integration:

   • Login Components: Update your login and signup components to include buttons for OAuth2 providers.
   • Frontend Routes: Implement frontend routes and components to handle OAuth2 login and signup processes.

8. Testing:

   • Unit Tests: Write unit tests for the OAuth2 authentication logic.
   • Integration Tests: Perform integration tests to ensure seamless communication between frontend, backend, and OAuth2 providers.

9. Documentation:

   • Update Readme: Document the newly added OAuth2 authentication features, including any necessary configuration changes.

10. Security Considerations:

    • Token Handling: Ensure secure handling and storage of OAuth2 access tokens.
    • HTTPS: Make sure your application is served over HTTPS for secure communication with OAuth2 providers.

Note: Keep sensitive information such as OAuth2 secrets and keys secure and not exposed in the repository.

May I suggest using NextAuth instead of passport ?
