BYOP Sample Application - Copilot Instructions

This is a multi-component web application designed for testing the BYOP (Build Your Own Platform) engine. When working on this project:

Project Context

Frontend: React 18 application with modern UI components
Backend: Node.js/Express API with PostgreSQL integration
Database: PostgreSQL with initialization scripts
Deployment: Docker containerization with multi-stage builds

Coding Guidelines

Frontend (React)

Use functional components with hooks
Implement proper error handling and loading states
Follow React best practices for state management
Use modern CSS with flexbox/grid layouts
Ensure responsive design principles

Backend (Node.js)

Use async/await for database operations
Implement proper error handling middleware
Follow RESTful API design principles
Include input validation and sanitization
Use environment variables for configuration

Docker & Deployment

Create multi-stage builds for production optimization
Include health checks in containers
Use non-root users for security
Optimize image sizes and build times
Follow Docker best practices

Testing Considerations

When suggesting code changes, consider:

Component isolation for BYOP testing
Environment variable flexibility
Health check endpoints
Graceful shutdown handling
Database connection resilience

BYOP-Specific Features

Each component should be independently deployable
Include proper service discovery configuration
Implement Traefik-compatible labeling
Support for different deployment environments
Clear separation of concerns between services
