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
