Summary: Phase 1, Plan 1 - Authentication Foundation

This plan implemented the foundational authentication system for the weekly task management application, establishing the core user management and session handling capabilities.

Key Deliverables

1. Prisma User Model: Created a complete User model with id, email, passwordHash, verifiedAt, createdAt, and updatedAt fields, including unique constraint on email.

2. Authentication API Endpoints:

   • POST /api/auth/signup - handles user registration with password hashing
   • POST /api/auth/login - handles user authentication with JWT token generation
   • POST /api/auth/logout - handles user session termination

3. Reusable Authentication Component:

   • Created AuthForm.tsx component with responsive design
   • Implemented form validation and error handling
   • Built with accessibility considerations

Implementation Details

The authentication system uses:

• JWT tokens stored in httpOnly cookies for secure session management
• jose library for JWT handling (avoiding CommonJS issues with Edge runtime)
• bcrypt for password hashing
• Prisma ORM for database interactions

Verification

All endpoints were tested and verified to:

• Properly handle signup, login, and logout flows
• Return appropriate HTTP status codes
• Store passwords securely with hashing
• Manage sessions across browser refreshes
• Render correctly on desktop and tablet devices

This foundation enables the complete authentication flow for users to create accounts, log in, and maintain sessions throughout their browsing experience.
