• Architects evaluating modern Python web frameworks

Learning Outcomes

After completing this training, participants will be able to:

• Design and implement RESTful APIs with FastAPI routing and path operations
• Validate request and response data with Pydantic models and schemas
• Build async endpoints for high-throughput API services
• Implement authentication and authorization with OAuth2 and JWT
• Generate and customize OpenAPI documentation automatically
• Test APIs thoroughly with pytest and httpx

Detailed Agenda

Day 1: FastAPI Foundations

Module 1: FastAPI Setup and Routing

• Project structure and application factory pattern
• Path operations: GET, POST, PUT, DELETE, PATCH
• Path parameters, query parameters, and request bodies
• Hands-on: Build a CRUD API for a resource management system

Module 2: Pydantic Models and Validation

• Defining request and response models
• Field validation, custom validators, and computed fields
• Nested models and model inheritance
• Hands-on: Implement comprehensive input validation for a booking API

Module 3: Dependency Injection

• FastAPI's dependency injection system
• Function and class dependencies
• Dependency chains and shared state
• Hands-on: Build a layered service architecture with DI

Day 2: Database Integration and Auth

Module 4: Database Integration

• SQLAlchemy ORM with async sessions
• Database models, migrations with Alembic
• Repository pattern for data access
• Hands-on: Connect the API to PostgreSQL with full CRUD operations

Module 5: Authentication and Security

• OAuth2 password flow with JWT tokens
• Token refresh and revocation
• Role-based access control and permissions
• Hands-on: Secure API endpoints with authentication and authorization

Module 6: Middleware and Error Handling

• Custom middleware for logging and CORS
• Exception handlers and error response models
• Rate limiting and request throttling
• Hands-on: Add production middleware stack to the API

Day 3: Production Readiness

Module 7: Async Patterns

• Async vs sync endpoints and when to use each
• Background tasks and task queues
• Streaming responses and WebSocket support
• Hands-on: Build async endpoints with background processing

Module 8: Testing and Documentation

• Testing with pytest and httpx TestClient
• Test fixtures, factories, and database isolation
• OpenAPI schema customization and documentation
• Hands-on: Achieve full test coverage for the API

Module 9: Deployment and Operations

• Running with Uvicorn and Gunicorn
• Docker containerization for FastAPI apps
• Health checks, structured logging, and monitoring
• Hands-on: Package and deploy the API with Docker Compose

Prerequisites

• Python Fundamentals or equivalent programming experience
• Comfort with functions, classes, and decorators
• Basic understanding of HTTP methods and REST concepts
• Familiarity with JSON data format
