🎯 Architecture Overview

JAEGIS employs a hybrid architecture that leverages the strengths of both Node.js and Python to create a high-performance, scalable command processing system with intelligent GitHub integration.

Design Principles

1. Performance First - Node.js for high-throughput command processing

2. Intelligence Focus - Python for AI/ML capabilities and complex data processing

3. Modular Design - Loosely coupled components with clear interfaces

4. Scalability - Horizontal scaling capabilities for both technologies

5. Maintainability - Clear separation of concerns and well-defined APIs

🔄 Inter-Process Communication

Communication Patterns

1. HTTP REST API - Primary communication method

2. Message Queues - Asynchronous task processing

3. Shared Cache - Redis for shared state

4. File System - Shared configuration and logs

5. WebSockets - Real-time updates

HTTP Bridge Architecture

// Node.js to Python Communication
class PythonBridge {
  constructor(config) {
    this.baseUrl = config.python.api_url
    this.timeout = config.python.timeout
    this.client = axios.create({
      baseURL: this.baseUrl,
      timeout: this.timeout,
      headers: {
        'Content-Type': 'application/json',
        'X-Source': 'nodejs-bridge'
      }
    })
  }

  async fetchGitHubCommands(url) {
    const response = await this.client.post('/github/fetch', {
      url: url,
      cache: true
    })
    return response.data
  }

  async parseMarkdown(content) {
    const response = await this.client.post('/processing/parse', {
      content: content,
      format: 'commands'
    })
    return response.data
  }
}

# Python API Endpoints
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel

app = FastAPI(title="JAEGIS Python Intelligence API")

class GitHubFetchRequest(BaseModel):
    url: str
    cache: bool = True

@app.post("/github/fetch")
async def fetch_github_content(request: GitHubFetchRequest):
    """Fetch and process GitHub content."""
    try:
        client = GitHubClient()
        content = await client.fetch_content(request.url)
        
        if request.cache:
            await client.cache_content(request.url, content)
            
        return {
            "success": True,
            "data": content,
            "cached": request.cache
        }

📊 Performance Optimization

Node.js Optimizations

1. Cluster Mode - Multi-process scaling

2. Connection Pooling - HTTP connection reuse

3. Memory Caching - In-memory command cache

4. Async/Await - Non-blocking operations

5. Stream Processing - Large data handling

// Cluster Configuration
const cluster = require('cluster')
const numCPUs = require('os').cpus().length

if (cluster.isMaster) {
  console.log(`Master ${process.pid} is running`)
  
  // Fork workers
  for (let i = 0; i < numCPUs; i++) {
    cluster.fork()
  }
  
  cluster.on('exit', (worker, code, signal) => {
    console.log(`Worker ${worker.process.pid} died`)
    cluster.fork()
  })
} else {
  // Worker process
  require('./app.js')
  console.log(`Worker ${process.pid} started`)
}

Python Optimizations

1. Async Processing - AsyncIO for I/O operations

2. Connection Pooling - HTTP session reuse

3. Caching Layers - Multi-level caching

4. Batch Processing - Bulk operations

5. Memory Management - Efficient data structures

# Async GitHub Client
import aiohttp
import asyncio
from typing import List, Dict

class AsyncGitHubClient:
    def __init__(self):
        self.session = None
        
    async def __aenter__(self):
        self.session = aiohttp.ClientSession()
        return self
        
    async def __aexit__(self, exc_type, exc_val, exc_tb):
        await self.session.close()
        
    async def fetch_multiple(self, urls: List[str]) -> List[Dict]:
        """Fetch multiple URLs concurrently."""
        tasks = [self.fetch_single(url) for url in urls]
        results = await asyncio.gather(*tasks)
        return results
        
    async def fetch_single(self, url: str) -> Dict:
        """Fetch single URL with error handling."""
        try:
            async with self.session.get(url) as response:
                content = await response.text()
                return {
                    "url": url,
                    "content": content,
                    "status": response.status
                }
        except Exception as e:
            return {
                "url": url,
                "error": str(e),

📈 Monitoring & Observability

Metrics Collection

// Node.js Monitoring
const prometheus = require('prom-client')

const httpRequestDuration = new prometheus.Histogram({
  name: 'http_request_duration_seconds',
  help: 'Duration of HTTP requests in seconds',
  labelNames: ['method', 'route', 'status']
})

const commandProcessingTime = new prometheus.Histogram({
  name: 'command_processing_duration_seconds',
  help: 'Duration of command processing in seconds',
  labelNames: ['command', 'success']
})

# Python Monitoring
from prometheus_client import Counter, Histogram, generate_latest

github_requests = Counter(
    'github_requests_total',
    'Total GitHub API requests',
    ['endpoint', 'status']
)

content_processing_time = Histogram(
    'content_processing_duration_seconds',
    'Time spent processing content',
    ['content_type']
)

Health Checks

// Node.js Health Check
app.get('/health', async (req, res) => {
  const health = {
    status: 'healthy',
    timestamp: new Date().toISOString(),
    services: {
      python_api: await checkPythonAPI(),
      redis: await checkRedis(),
      github: await checkGitHub()
    }
  }
  
  const isHealthy = Object.values(health.services)
    .every(service => service.status === 'healthy')
    
  res.status(isHealthy ? 200 : 503).json(health)
})

🔒 Security Considerations

Authentication & Authorization

1. API Key Management - Secure GitHub token storage

2. Input Validation - Comprehensive input sanitization

3. Rate Limiting - API and command rate limits

4. CORS Configuration - Proper cross-origin settings

5. Encryption - Data encryption at rest and in transit

Security Implementation

// Security Middleware
const helmet = require('helmet')
const rateLimit = require('express-rate-limit')

app.use(helmet())
app.use(rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
}))

// Input validation
const joi = require('joi')

const commandSchema = joi.object({
  command: joi.string().max(1000).required(),
  parameters: joi.object().optional()
})
