# Next.js Migration Plan

## Overview
This document outlines the strategy for migrating ThrillWiki from a Django monolith to a Next.js frontend with API Routes backend while maintaining all existing functionality and design.

## Current Architecture
- Django monolithic application
- Django templates with HTMX and Alpine.js
- Django views handling both API and page rendering
- Django ORM for database operations
- Custom analytics system
- File upload handling through Django
- Authentication through Django

## Target Architecture
- Next.js 14+ application using App Router
- React components replacing Django templates
- Next.js API Routes replacing Django views
- Prisma ORM replacing Django ORM
- JWT-based authentication system
- Maintain current DB schema
- API-first approach with type safety
- File uploads through Next.js API routes

## Component Mapping
Major sections requiring migration:

1. Parks System:
   - Convert Django views to API routes
   - Convert templates to React components
   - Implement dynamic routing
   - Maintain search functionality

2. User System:
   - Implement JWT authentication
   - Convert user management to API routes
   - Migrate profile management
   - Handle avatar uploads

3. Reviews System:
   - Convert to API routes
   - Implement real-time updates
   - Maintain moderation features

4. Analytics:
   - Convert to API routes
   - Implement client-side tracking
   - Maintain current metrics

## API Route Mapping
```typescript
// Example API route structure
/api
  /auth
    /login
    /register
    /profile
  /parks
    /[id]
    /search
    /nearby
  /reviews
    /[id]
    /create
    /moderate
  /analytics
    /track
    /stats
```

## Migration Phases

### Phase 1: Setup & Infrastructure
1. Initialize Next.js project
2. Set up Prisma with existing schema
3. Configure TypeScript
4. Set up authentication system
5. Configure file upload handling

### Phase 2: Core Features
1. Parks system migration
2. User authentication
3. Basic CRUD operations
4. Search functionality
5. File uploads

### Phase 3: Advanced Features
1. Reviews system
2. Analytics
3. Moderation tools
4. Real-time features
5. Admin interfaces

### Phase 4: Testing & Polish
1. Comprehensive testing
2. Performance optimization
3. SEO implementation
4. Security audit
5. Documentation updates

## Dependencies

### Frontend
- next: ^14.0.0
- react: ^18.2.0
- react-dom: ^18.2.0
- @prisma/client
- @tanstack/react-query
- tailwindcss
- typescript
- zod (for validation)
- jwt-decode
- @headlessui/react

### Backend
- prisma
- jsonwebtoken
- bcryptjs
- multer (file uploads)
- sharp (image processing)

## Data Migration Strategy
1. Create Prisma schema matching Django models
2. Write migration scripts for data transfer
3. Validate data integrity
4. Implement rollback procedures

## Security Considerations
1. JWT token handling
2. CSRF protection
3. Rate limiting
4. File upload security
5. API route protection

## Performance Optimization
1. Implement ISR (Incremental Static Regeneration)
2. Optimize images and assets
3. Implement caching strategy
4. Code splitting
5. Bundle optimization

## Rollback Plan
1. Maintain dual systems during migration
2. Database backup strategy
3. Traffic routing plan
4. Monitoring and alerts
