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
