Python FastAPI Development Best Practices Comprehensive guide for building production-ready APIs with FastAPI, async Python, and modern backend development patterns. Project Structure Modular Application Architecture Organize code into logical modules (routers, models, schemas, services) Separate business logic from API logic Example structure: Configuration Management Use Pydantic BaseSettings for environment-based configuration Keep sensitive data in environment variables Implement different configs for development, testing, and production Example: Database Integration SQLAlchemy Async Patterns Use asyncio-compatible database drivers (asyncpg for PostgreSQL) Implement async session management Use select() for queries instead of legacy query() methods Example: Database Models and Relationships Define clear SQLAlchemy models with proper relationships Use appropriate column types and constraints Implement proper indexing for performance Example: Database Migrations Use Alembic for database schema migrations Create meaningful migration messages and version control Test migrations in development before applying to production Example migration workflow: Error Handling and Validation Custom Exception Handling Create custom exception classes for different error types Implement global exception handlers Return consistent error response formats Example: Input Validation Use Pydantic validators for complex validation logic Implement custom validators for business rules Provide clear error messages for validation failures Example: Testing Test Structure Write comprehensive unit tests for all business logic Implement integration tests for API endpoints Use pytest with async support for testing Example: Test Database Management Use separate test databases for isolation Implement database fixtures for test data Clean up test data after each test run Summary Checklist [ ] Use type hints and Pydantic models throughout [ ] Implement async/await for all I/O operations [ ] Structure project with clear separation of concerns [ ] Use dependency injection for shared logic [ ] Implement proper authentication and authorization [ ] Handle errors consistently with custom exceptions [ ] Optimize database queries and implement caching [ ] Write comprehensive tests for all functionality [ ] Use proper security headers and HTTPS [ ] Configure production deployment with Docker [ ] Implement monitoring and logging Follow these practices to build robust, scalable, and maintainable FastAPI applications.
