# Next.js Migration Progress

## Current Status (Updated 2/23/2025)

### Completed Setup
1. ✅ Next.js project initialized in frontend/
2. ✅ TypeScript configuration
3. ✅ Prisma setup with PostGIS support
4. ✅ Environment configuration
5. ✅ API route structure
6. ✅ Initial database schema sync
7. ✅ Basic UI components

### Database Migration Status
- Detected existing Django schema with 70+ tables
- Successfully initialized Prisma with PostGIS extension
- Created initial migration

### Key Database Tables Identified
1. Core Tables
   - accounts_user
   - parks_park
   - reviews_review
   - location_location
   - media_photo

2. Authentication Tables
   - socialaccount_socialaccount
   - token_blacklist_blacklistedtoken
   - auth_permission

3. Content Management
   - wiki_article
   - wiki_articlerevision
   - core_slughistory

### Implemented Features
1. Authentication Middleware
   - Basic JWT token validation
   - Public/private route handling
   - Token forwarding
   
2. API Types System
   - Base response types
   - Park types
   - User types
   - Review types
   - Error handling types

3. Database Connection
   - Prisma client setup
   - PostGIS extension configuration
   - Development/production handling

4. Parks API Route
   - GET endpoint with pagination
   - Search functionality
   - POST endpoint with auth
   - Error handling

## Next Steps (Prioritized)

### 1. Schema Migration (Current Focus)
- [ ] Map remaining Django models to Prisma schema
- [ ] Handle custom field types (e.g., GeoDjango fields)
- [ ] Set up relationships between models
- [ ] Create data migration scripts

### 2. Authentication System
- [ ] Implement JWT verification
- [ ] Set up refresh tokens
- [ ] Social auth integration
- [ ] User session management

### 3. Core Features Migration
- [ ] Parks system
- [ ] User profiles
- [ ] Review system
- [ ] Media handling

### 4. Testing & Validation
- [ ] Unit tests for API routes
- [ ] Integration tests
- [ ] Data integrity checks
- [ ] Performance testing

## Technical Decisions

### Schema Migration Strategy
- Incremental model migration
- Maintain foreign key relationships
- Handle custom field types via Prisma
- Use PostGIS for spatial data

### Authentication Approach
- JWT for API authentication
- HTTP-only cookies for token storage
- Refresh token rotation
- Social auth provider integration

### API Architecture
- REST-based endpoints
- Strong type safety
- Consistent response formats
- Built-in pagination
- Error handling middleware

### Component Architecture
- Server components by default
- Client components for interactivity
- Shared component library
- Error boundaries

## Migration Challenges

### Current Challenges
1. Complex Django model relationships
2. Custom field type handling
3. Social authentication flow
4. File upload system
5. Real-time feature migration

### Solutions
1. Using Prisma's preview features for PostGIS
2. Custom field type mappings
3. JWT-based auth with refresh tokens
4. S3/cloud storage integration
5. WebSocket/Server-Sent Events

## Monitoring & Validation

### Data Integrity
- Validation scripts for migrated data
- Comparison tools for Django/Prisma models
- Automated testing of relationships
- Error logging and monitoring

### Performance
- API response time tracking
- Database query optimization
- Client-side performance metrics
- Error rate monitoring

## Documentation Updates
1. API route specifications
2. Schema migration process
3. Authentication flows
4. Component documentation
5. Deployment guides

## Rollback Strategy
1. Maintain Django application
2. Database backups before migrations
3. Feature flags for gradual rollout
4. Monitoring thresholds for auto-rollback
