FastAPI has become the default framework for new Python APIs in 2026, valued for its async-first architecture, automatic OpenAPI 3.1 documentation, and Rust-powered Pydantic v2 validation. This FastAPI Course moves beyond basic CRUD tutorials to cover real production concerns: structured concurrency, database session management, background jobs, WebSockets, observability, containerized deployment, and serving machine-learning models behind typed endpoints – the exact skill set hiring managers now screen for in backend interviews.
Prerequisites
- Working knowledge of Python (functions, classes, modules, decorators)
- Basic understanding of HTTP methods, status codes, and JSON
- Familiarity with REST API concepts such as endpoints and CRUD operations
- Comfort using the command line and basic Git commands
- A code editor such as VS Code or PyCharm installed on your system
- Exposure to SQL or general database concepts is helpful but not mandatory
- No prior FastAPI or async Python experience is required – this track also works as FastAPI for Beginners with a working Python foundation
Course Objectives
- Understand why FastAPI has become a leading choice for building modern, high-performance APIs in Python
- Build and structure production-ready REST APIs using routers, dependency injection, and clean architecture
- Apply Pydantic v2 for request validation, response modeling, and data serialization
- Implement authentication and authorization using OAuth2, JWT, and API keys
- Connect applications to relational and non-relational databases using async ORMs
- Write asynchronous, non-blocking endpoints that scale under real concurrent load
- Test, monitor, containerize, and deploy services to cloud infrastructure
- Complete a portfolio-ready capstone project that mirrors real employer expectations
What You Will Learn
- Design typed, self-documenting REST APIs using FastAPI’s path operations and Pydantic v2 schemas
- Handle path parameters, query parameters, headers, cookies, and complex request bodies
- Build async database layers with SQLAlchemy 2.0’s AsyncSession and Alembic migrations
- Secure endpoints with the OAuth2 password flow, JWT tokens, scopes, and role-based access control
- Structure large applications using APIRouter, dependency injection, and layered service design
- Run background tasks, schedule jobs, and stream real-time data over WebSockets
- Reduce latency with uvloop, ORJSONResponse, connection pooling, and response-model tuning
- Write automated tests with pytest, pytest-asyncio, and HTTPX test clients
- Add structured logging, metrics, and distributed tracing with OpenTelemetry
- Containerize services with Docker and deploy them through CI/CD pipelines to AWS, Azure, or GCP
- Expose machine-learning and LLM inference endpoints safely for AI-driven applications
- Version APIs, manage backward compatibility, and generate OpenAPI 3.1 documentation automatically
