# ConvertX OpenAPI Implementation Summary

## ✅ Completed Features

### 1. Project Setup
- **CLAUDE.md**: Complete codebase documentation
- **Slash Commands**: `/commit`, `/pr`, `/test`, `/build` helpers
- **Environment Configuration**: `.env.development` with API settings

### 2. CI/CD Enhancements
- **docker-publish-custom.yml**: Supports custom Docker registries
- **docker-compose.yml**: Multi-profile setup (dev, prod, monitoring)
- **Registry Configuration**: Environment variable based registry selection

### 3. API Implementation
- **Base Structure**: `/api/v1` endpoints with modular organization
- **Health Check**: `/api/v1/health` - System status monitoring
- **Authentication**: 
  - `POST /api/v1/auth/register` - User registration
  - `POST /api/v1/auth/login` - JWT token generation
  - `GET /api/v1/auth/me` - Current user info
  - `POST /api/v1/auth/logout` - Session cleanup
- **Converters**:
  - `GET /api/v1/converters` - List all converters
  - `GET /api/v1/converters/:name` - Converter details
  - `GET /api/v1/converters/formats/:format` - Find converters by format
- **Jobs**:
  - `GET /api/v1/jobs` - List user jobs
  - `GET /api/v1/jobs/:id` - Job details
  - `DELETE /api/v1/jobs/:id` - Delete job
- **Files**:
  - `GET /api/v1/files/:jobId` - List job files
  - `GET /api/v1/files/:jobId/:fileName` - Download file
- **Conversions**:
  - `POST /api/v1/conversions` - Start conversion (partial implementation)

### 4. Documentation & Testing
- **API.md**: Complete API documentation
- **test-api.sh**: Automated API testing script
- **CORS**: Full CORS support for browser-based clients

## 🚧 Known Issues & Limitations

### 1. Authentication Context
- JWT verification in middleware needs fixing
- Currently requires `ALLOW_UNAUTHENTICATED=true` for testing
- User context not properly passed to route handlers

### 2. File Upload
- Conversion endpoint expects pre-uploaded files
- Multipart file upload not yet implemented
- Need to integrate with existing upload logic

### 3. Swagger/OpenAPI
- Swagger UI disabled due to Elysia composition error
- OpenAPI spec generation needs debugging
- Alternative: Manual API documentation provided

## 🔮 Next Steps

### Phase 2: Core Functionality
1. Fix JWT authentication middleware
2. Implement multipart file upload
3. Complete conversion endpoint with actual file processing
4. Add progress tracking via SSE or WebSockets

### Phase 3: Enhanced Features
1. API key authentication
2. Rate limiting implementation
3. Webhook notifications
4. Batch conversion support

### Phase 4: Production Ready
1. Re-enable Swagger UI
2. Add comprehensive error handling
3. Implement request/response logging
4. Performance optimization
5. API versioning strategy

## 📝 Usage

### Development
```bash
# Install dependencies
bun install

# Start with API enabled
export $(cat .env.development | xargs) && bun run dev

# Test API
./test-api.sh
```

### Docker
```bash
# Development with hot reload
docker compose --profile dev up

# Production
docker compose up convertx
```

## 🔧 Configuration

Key environment variables:
- `API_ENABLED=true` - Enable API endpoints
- `ALLOW_UNAUTHENTICATED=true` - Allow anonymous access (dev only)
- `JWT_SECRET` - Secret for JWT signing
- `API_RATE_LIMIT` - Requests per window
- `API_RATE_WINDOW` - Rate limit time window

## 🏗️ Architecture Notes

- API code isolated in `src/api/` directory
- Minimal changes to existing codebase
- Reuses existing converter logic
- Compatible with current database schema
- Can be disabled via environment variable

The foundation is solid and ready for the remaining features to be implemented in subsequent phases.
