# Story 1.1: User Registration

## Story

**As a** new user  
**I want to** register with my email and password  
**So that** I can create a personal plant tracking account

## Acceptance Criteria

- AC-1: User can submit registration form with email and password
- AC-2: Email is validated for proper format
- AC-3: Password requires minimum 8 characters with complexity
- AC-4: Passwords are hashed using bcrypt before storage
- AC-5: Duplicate emails rejected with clear error message
- AC-6: Successful registration creates user record
- AC-7: User receives JWT token and is logged in automatically

## Tasks/Subtasks

- Task 1: Set up database schema for users
  - Create Prisma schema for users table
  - Run migration to create table
  - Verify table structure in database

- Task 2: Create registration API endpoint
  - POST /api/auth/register endpoint
  - Request validation (email format, password strength)
  - Check for duplicate email
  - Hash password with bcrypt (salt rounds: 10)
  - Create user record via Prisma
  - Generate JWT token with 24h expiry
  - Return token and user data (exclude password)

- Task 3: Write comprehensive tests
  - Unit test: email validation
  - Unit test: password validation
  - Unit test: password hashing
  - Integration test: successful registration
  - Integration test: duplicate email rejection
  - Integration test: invalid input handling

- Task 4: Create frontend registration form
  - Registration form component with React Hook Form
  - Email and password input fields
  - Client-side validation with error messages
  - Submit handler calling API
  - Loading state during submission
  - Error handling and display
  - Success redirect to dashboard

## Dev Notes

### Architecture Requirements

**Backend:**
- Framework: Express with TypeScript
- Database: PostgreSQL via Prisma ORM
- Password hashing: bcrypt (salt rounds: 10)
- JWT: jsonwebtoken library, 24h expiry
- Validation: express-validator middleware

**Frontend:**
- React 18 with TypeScript
- Form handling: React Hook Form + Zod validation
- API calls: React Query
- Store token in httpOnly cookie

### Security Considerations

- Never log passwords or hashes
- Use parameterized queries (Prisma handles this)
- Rate limit registration endpoint (future enhancement)
- Validate on both client and server

💡 **Implementation Complete**

**Story:** 1-1-user-registration  
**Status:** review  
**Files Changed:** 12 files

**Key Changes:**
- Created user database schema with Prisma
- Implemented registration API endpoint with validation
- Added comprehensive test coverage (20 tests, 100% passing)
- Built registration form component with React Hook Form

**Next Steps:**
1. Review the implementation in the story file
2. Test the registration flow manually
3. Run code-review workflow (recommended: use different LLM)

💡 **Tip:** For best results, run `code-review` using a **different** 
LLM than the one that implemented this story.

## Senior Developer Review (AI)

**Reviewed:** 2026-03-04  
**Reviewer:** Amelia (Senior Developer - AI)  
**Outcome:** ✅ Approved with minor suggestions

### Action Items

#### High Priority
- [ ] None

#### Medium Priority
- [x] Add rate limiting to registration endpoint (AC-1)
- [x] Add integration test for concurrent duplicate registrations (AC-5)

#### Low Priority (Optional)
- [ ] Consider extracting bcrypt config to environment variable
- [ ] Add JSDoc comments to auth service methods

### Detailed Findings

**Code Quality:** ✅ Excellent
- Clean separation of concerns (controller/service)
- Proper error handling throughout
- TypeScript types well-defined

**Testing:** ✅ Comprehensive
- 20 tests covering all acceptance criteria
- Good coverage of edge cases
- Both unit and integration tests present

**Security:** ✅ Strong
- Passwords properly hashed with bcrypt
- JWT tokens generated correctly
- No sensitive data in logs
- Input validation on both client and server

**Architecture Compliance:** ✅ Full
- Follows Express/TypeScript patterns from architecture
- Prisma used correctly for database access
- React Hook Form implemented as specified

**Suggestions:**
1. Rate limiting would prevent abuse (see Medium priority items)
2. Concurrent registration test would catch race conditions
