Create complete travel assistant with FastAPI backend, Next.js frontend, and Docker Compose setup

[Copilot]

This PR implements a complete AI-powered travel assistant application with separate backend and frontend components, fully containerized with Docker Compose.

🏗️ Architecture Overview

The application is structured into three main components:

• Backend: FastAPI application with PostgreSQL database
• Frontend: Next.js application with TypeScript
• Infrastructure: Docker Compose for orchestration

🎯 Backend Implementation (backend/)

Created a FastAPI application with the following features:

• RESTful API with endpoints for travel recommendations and search
• PostgreSQL integration using SQLAlchemy ORM for data persistence
• CORS configuration to enable frontend communication
• Environment-based configuration for flexible deployment
• Health check endpoints for monitoring and container orchestration

Key endpoints implemented:

• GET / - Root endpoint
• GET /health - Health check
• GET /recommendations - Retrieve all travel destinations
• GET /recommendations/{destination} - Get specific destination details
• POST /search - Search destinations with filters (budget, dates, preferences)

🎨 Frontend Implementation (frontend/)

Developed a Next.js application with modern React patterns:

• Next.js 14 with App Router for optimal performance and SEO
• TypeScript with strict type checking for code reliability
• Styled Components for component-scoped CSS and responsive design
• API integration with custom hooks and error handling
• Search interface with budget filtering and date selection
• Recommendation cards displaying destination details and highlights

🐳 Docker Configuration

Created comprehensive containerization setup:

• Production configuration (docker-compose.yml) with optimized builds
• Development configuration (docker-compose.dev.yml) with hot reload
• PostgreSQL service with health checks and data persistence
• Network configuration for secure inter-service communication
• Volume management for database persistence and development workflows

📊 Sample Data & Database Schema

Included PostgreSQL initialization with:

• Destinations table with travel information, costs, and highlights
• Travel plans table for future user itinerary features
• Sample data for popular destinations (Paris, Tokyo, New York, Barcelona)

🚀 Easy Deployment

Added convenience features for development:

• Startup script (start.sh) for one-command deployment
• Environment examples with clear configuration options
• Documentation with setup instructions and troubleshooting guide

✅ Testing & Validation

All components have been tested and validated:

• FastAPI endpoints return correct responses with proper HTTP status codes
• Next.js application builds successfully with TypeScript type checking
• Docker Compose configuration validated and services start correctly
• API integration tested with search functionality and data retrieval

🔧 Usage

# Start in development mode (with hot reload)
./start.sh

# Start in production mode
./start.sh prod

# Access the application
# Frontend: http://localhost:3000
# Backend API: http://localhost:8000
# API Documentation: http://localhost:8000/docs

This implementation provides a solid foundation for an AI travel assistant with modern web technologies, proper separation of concerns, and production-ready containerization.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• fonts.googleapis.com
  • Triggering command: /usr/local/bin/node /home/REDACTED/work/TravelAssistant/TravelAssistant/frontend/node_modules/next/dist/compiled/jest-worker/processChild.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
