Summary

Complete implementation of secure user authentication system using Supabase Auth with comprehensive session management and security features.

πŸš€ Key Features Implemented

  • βœ… User Registration: Email/password registration with Supabase email verification
  • βœ… Secure Login: JWT token generation with httpOnly cookie storage
  • βœ… Session Management: Automatic token refresh, persistent sessions across page refreshes
  • βœ… Profile Management: Email and name updates with real-time validation
  • βœ… Protected Routes: Authentication guards for dashboard and profile pages

πŸ”’ Security Implementation

  • Token Security: JWT tokens stored in secure httpOnly cookies with SameSite policies
  • Environment-Aware Security: Strict settings for production, development-friendly for local testing
  • Password Hashing: Handled securely by Supabase Auth infrastructure
  • Cross-Origin Support: Proper CORS configuration for development and production environments
  • Session Validation: Server-side session checking with automatic cleanup

πŸ›  Critical Technical Fixes

  • Browser Compatibility: Resolved Node.js dependency conflicts in browser environment
  • Session Persistence: Fixed session destruction on page refresh with hybrid localStorage + API approach
  • Authentication Standardization: Unified cookie-based authentication across all endpoints
  • Runtime Bug Fixes: Resolved sessionData undefined errors in session validation

πŸ— Architecture Highlights

  • React Context API: Global authentication state management with useAuth hook
  • Comprehensive Error Handling: Zod schema validation and user-friendly error messages
  • Modular Design: Clean separation between auth types, services, and UI components
  • Production-Ready: Environment-aware configuration for seamless deployment

Test Plan

βœ… Authentication Flow Testing

  • Registration: Create new account with email verification
  • Login: Successful authentication with session creation
  • Session Persistence: Verify sessions survive page refreshes and browser restarts
  • Profile Updates: Email and name changes with proper validation
  • Protected Routes: Dashboard and profile redirect to login when unauthenticated
  • Logout Flow: Session cleanup and redirect to login (when AC6 is implemented)

βœ… Security Validation

  • Cookie Security: Verify httpOnly, SameSite, and Secure flags in production
  • CORS Configuration: Test cross-origin requests work properly
  • Token Refresh: Automatic session renewal without user intervention
  • Session Expiry: Proper cleanup of expired sessions

βœ… Cross-Browser Testing

  • Chrome/Safari: Verify authentication works across major browsers
  • Mobile Responsive: Test authentication flow on mobile devices
  • Network Conditions: Test with slow/intermittent connections

Story Progress

Story 1.2 Acceptance Criteria Status:

  • βœ… AC1: User registration with email/password validation
  • βœ… AC2: Secure login with JWT token generation
  • βœ… AC3: Password hashing with bcrypt (via Supabase)
  • βœ… AC4: Session management with secure token storage
  • βœ… AC5: Basic profile management (email, name)
  • ⏳ AC6: Logout functionality that invalidates tokens (UI integration pending)
  • ⏳ AC7: Password reset capability via email (pending)

Deployment Notes

Production Environment Variables Required:

  • SUPABASE_URL: Your Supabase project URL
  • SUPABASE_ANON_KEY: Supabase anonymous key
  • SUPABASE_SERVICE_ROLE_KEY: Service role key for server-side operations
  • NODE_ENV=production: Enables strict security policies

Vercel Configuration:

  • All environment variables configured in Vercel dashboard
  • Frontend and API deployed on same domain for cookie security
  • Automatic HTTPS enforces secure cookie policies

Resolves production 'Network error' by creating actual API endpoints:

**New Vercel Functions:**
- /api/auth/register - User registration with Supabase Auth
- /api/auth/login - User login with secure cookie sessions
- /api/auth/session - Session validation and refresh
- /api/auth/logout - Session cleanup and logout
- /api/profile/me - Profile management (GET/PUT)

**Key Features:**
- Environment-aware CORS and security settings
- Secure httpOnly cookie session management
- Supabase Auth integration with service role key
- Comprehensive error handling and validation
- Production-ready with proper TypeScript types

**Fixes:**
- 'Network error. Please try again.' on registration in production
- Missing API endpoints that were only available in dev-server.js locally

Fixes overly permissive CORS configuration:

**Security Improvements:**
- Production: No CORS header = same-origin only (most secure)
- Development: Explicit localhost:5173 allow for Vite dev server
- Removes wildcard '*' origin that allowed any domain

**Changes Applied:**
- api/auth/login.ts - Secure CORS policy
- api/auth/register.ts - Secure CORS policy
- api/auth/session.ts - Secure CORS policy
- api/auth/logout.ts - Secure CORS policy
- api/profile/me.ts - Secure CORS policy

**Benefits:**
- Prevents cross-origin attacks in production
- Maintains development workflow compatibility
- Follows security best practices for Vercel deployment

Fixes broken database health endpoint caused by incorrect import paths:

**Issues Fixed:**
- Remove invalid import paths (../../lib/utils/supabase, ../../lib/utils/response)
- Use @supabase/supabase-js directly like other API functions
- Add consistent CORS security policy
- Use standard response format with success/error structure

**Changes:**
- Replace broken utility imports with direct Supabase client creation
- Add environment-aware CORS headers for security
- Consistent error handling and response format
- Proper environment variable validation

**Result:**
- /api/database/health endpoint now works in production
- Consistent with other API function patterns
- Secure CORS policy applied
