The Power of Dependency Injection
FastAPI's dependency injection system is so elegant. Need a database session? Just add it as a parameter. Need the current user? Same thing. It makes the code so clean and testable.
Tips for API Design
Use nouns for resources (/users, /posts), HTTP verbs for actions (GET, POST, PUT, DELETE), and return consistent responses. FastAPI's response_model helps enforce this consistency.
Environment Variables and Security
Never hardcode secrets! Use environment variables and pydantic-settings to keep your API keys, database URLs, and JWT secrets safe. It's Security 101.
Background Tasks in FastAPI
Don't make users wait for emails to send or files to process. FastAPI's BackgroundTasks lets you return immediately while work continues in the background.
The ORM vs Raw SQL Debate
ORMs like SQLAlchemy add abstraction but can hide performance issues. Know when to use the ORM and when to drop to raw SQL. Both have their place.
OpenAPI Schema Customization
FastAPI's auto-generated OpenAPI schema is great, but sometimes you need to customize. Add examples, descriptions, and tags to make your docs shine.
