Create mock backend to simulate AI responses for UI development: Backend Implementation: - tools/fake-backend/server.js: Express server with CORS - POST /api/analyze: Accepts log, returns mock AI analysis with 1.5s delay - GET /health: Health check endpoint - Pattern matching for different log types (PostgreSQL, Nginx, Node.js, Disk) - Error handling: 400 for empty payload, 500 for server errors - Mock responses for common errors (OOM, 502, connection refused, disk full) Container Setup: - Dockerfile: Node.js 20 Alpine container - docker-compose.yml: Added fake-backend service on port 3000 - Health checks for both frontend and backend services - Environment variable VITE_API_URL for frontend Frontend Integration: - InteractiveDemo.tsx: Replaced static data with real fetch() calls - API_URL configurable via env var (default: http://localhost:3000) - Error handling with user-friendly messages - Shows backend URL in demo section - Maintains loading states and UI feedback Documentation: - docs/tools_fake_backend.md: Complete usage guide - README.md: Updated with tools/fake-backend structure and usage Development Workflow: 1. docker compose up -d (starts both frontend and backend) 2. Frontend calls http://fake-backend:3000/api/analyze 3. Backend returns realistic mock responses 4. No OpenRouter API costs during development Safety First: - No real API calls during development - Isolated mock logic in dedicated tool - Easy switch to real backend by changing URL - CORS enabled only for development Refs: Sprint 4 preparation, API development workflow
