Integration Points

1. Django Backend

• Serves as the main web server
• Handles user sessions and authentication
• Manages database operations through Django ORM
• Provides REST API endpoints
• Renders HTML templates
• Serves static files

2. Go Services

• Provides high-performance API endpoints
• Manages Redis caching layer
• Handles compute-intensive tasks
• Processes background jobs
• Offers real-time capabilities through WebSocket

3. TypeScript Frontend

• Compiles to JavaScript for browser execution
• Communicates with both Django and Go services
• Manages client-side state
• Handles user interactions
• Provides type-safe development

Development Workflow

1. Setup Development Environment:

   # Install all dependencies
   make install

2. Start Development Servers:

   # Using docker-compose (recommended)
   make run
   
   # Or manually:
   cd backend/django_project
   python manage.py runserver
   
   cd backend/go_services
   go run cmd/api/main.go
   
   cd frontend
   npm run dev

3. Access Development Servers:

   • Django: http://localhost:8000
   • Go services: http://localhost:8080
   • Frontend dev server: http://localhost:3000

Practical Use Cases

1. User Authentication Flow

• Django handles user registration and authentication
• Session management through Django's auth system
• TypeScript frontend manages login forms and validation
• Go services handle session verification for high-performance endpoints

2. Data Processing Pipeline

• User submits data through TypeScript frontend
• Django validates and stores the data
• Go services process the data in background
• Redis caches processed results
• Real-time updates sent to frontend

3. Real-time Features

• Go services manage WebSocket connections
• TypeScript frontend maintains socket connection
• Real-time updates through Go's efficient concurrency
• Django handles persistent storage of real-time data

4. High-Performance Operations

• Static content served by Django
• Compute-intensive operations handled by Go
• Caching layer managed by Go and Redis
• TypeScript handles client-side caching

Best Practices

Django (Python)

• Type hints for better code quality
• Modular settings for different environments
• Django REST Framework for APIs
• Proper authentication and authorization
• Environment variable configuration
