  • Spatial queries for proximity-based searches

• Weather Data

  • Historical weather data storage and retrieval
  • Weather forecasts integration
  • Weather condition tracking

• Security & Performance

  • ✅ JWT-based authentication
  • 🔒 Role-based access control
  • 🛡️ Rate limiting and request throttling
  • 🔄 API versioning support
  • 📊 Comprehensive request/response logging
  • 🚀 Optimized for high performance

• Developer Experience

  • 📚 Comprehensive API documentation
  • ✅ Type hints and static type checking
  • 🧪 Test coverage
  • 🔄 CI/CD ready
  • 🐳 Docker support

🚀 Quick Start

Prerequisites

• Python 3.10+
• PostgreSQL 13+ (or SQLite for development)
• Redis (for rate limiting and caching)
• Docker (optional, for containerized deployment)

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/climate-risk-api.git
   cd climate-risk-api

2. Create and activate a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

   pip install -e ".[dev]"

4. Configure environment variables:

   cp .env.example .env
   # Edit .env with your configuration

5. Initialize the database:

   alembic upgrade head

6. Run the development server:

   # Development (auto-reload)
   uvicorn src.app:app --reload
   
   # Production
   # uvicorn src.app:app --host 0.0.0.0 --port 8000 --workers 4

7. Or run with Docker Compose (recommended for production):

   docker-compose up -d --build

📚 API Documentation

Once the application is running, you can access the following documentation:

• Swagger UI: http://localhost:8000/api/v1/docs
• ReDoc: http://localhost:8000/api/v1/redoc
• OpenAPI Schema: http://localhost:8000/api/v1/openapi.json

API Versioning

TheAPI uses semantic versioning (e.g., v1.0.0). You can specify the API version in multiple ways:

1. URL Path: /api/v1/endpoint
2. Header: Accept: application/vnd.api.v1+json
3. Query Parameter: /api/endpoint?version=1
4. Cookie: api-version=1

🔒 Security

The API includes several security features:

Rate Limiting

• Default: 100 requests per minute per IP
• Configurable via environment variables
• Supports Redis for distributed rate limiting

Security Headers

• Content Security Policy (CSP)
• X-Content-Type-Options
• X-Frame-Options
• X-XSS-Protection
• HSTS (HTTP Strict Transport Security)
• Referrer-Policy
• Permissions-Policy

Authentication

• JWT-based authentication
• Role-based access control (RBAC)
• Secure password hashing
• Token refresh mechanism

📊 Monitoring & Logging

Logging

• Structured JSON logging
• Request/response logging
• Sensitive data redaction
• Correlation IDs for request tracing

Monitoring

• Health check endpoint (/health)
• Metrics endpoint (/metrics)
• Performance monitoring
• Error tracking
