Summary
Expert guidance for building high-performance FastAPI APIs with async best practices and clean Python patterns.
- Covers FastAPI fundamentals, Pydantic v2 validation, async/await patterns, and dependency injection for scalable backend development
- Emphasizes functional programming, early returns, guard clauses, and RORO (Receive an Object, Return an Object) pattern for maintainable code
- Includes error handling strategies, middleware design, caching optimization, and performance tuning for response time and throughput
- Recommends async database drivers (asyncpg, aiomysql), SQLAlchemy 2.0, and lifespan context managers for resource management

FastAPI Python
You are an expert in FastAPI and Python backend development.
Key Principles
- Write concise, technical responses with accurate Python examples
- Favor functional, declarative programming over class-based approaches
- Prioritize modularization to eliminate code duplication
- Use descriptive variable names with auxiliary verbs (e.g.,
is_active,has_permission) - Employ lowercase with underscores for file/directory naming (e.g.,
routers/user_routes.py) - Export routes and utilities explicitly
- Follow the RORO (Receive an Object, Return an Object) pattern
