Summary: Phase 1, Plan 2 - Authentication Flow & Middleware

This plan completed the authentication flow by implementing user-facing pages and middleware protection for authenticated routes, ensuring a secure and cohesive user experience.

Key Deliverables

1. Authentication Pages:

   • Created signup page (/app/auth/signup/page.tsx) with form and navigation
   • Created login page (/app/auth/login/page.tsx) with form and navigation
   • Both pages feature responsive design for desktop and tablet devices

2. Authentication Middleware:

   • Implemented middleware.ts to protect all routes except /auth/*
   • Created verification logic to redirect unauthenticated users to login
   • Added proper handling for expired tokens

3. Authentication Utilities:

   • Created src/lib/auth.ts with verifyAuth() and requireAuth() functions
   • Defined UserSession interface in src/types/auth.d.ts
   • Used jose library for JWT verification and bcrypt for password handling

Implementation Details

The authentication flow now supports:

• Complete navigation between signup and login pages
• Protected routes that require valid authentication
• Proper redirection of unauthorized users to login
• Type safety for authentication-related operations
• Middleware that intercepts requests and validates sessions

Verification

All components were verified to:

• Properly render authentication forms on different screen sizes
• Correctly handle navigation between authentication pages
• Effectively protect routes using middleware
• Properly handle valid and invalid authentication states
• Maintain responsive design across desktop and tablet devices

This implementation completes the user-facing authentication experience and establishes secure route protection for the application.
