Type Hints Changed My Life
I used to think type hints were just extra typing (pun intended). But after using FastAPI, I see how they enable incredible tooling - better autocomplete, automatic validation, and self-documenting code.
JWT Authentication Demystified
JSON Web Tokens seemed scary at first, but they're actually pretty simple. Encode some user data, sign it with a secret, and use it to verify requests. FastAPI + PyJWT makes it straightforward.
Testing FastAPI Applications
FastAPI's TestClient makes testing a breeze. Write tests for your endpoints, mock dependencies, and catch bugs before they hit production. Your future self will thank you.
API Versioning Strategies
APIs evolve. Version them from day one! Whether you use URL prefixes (/v1/users) or headers, plan for change. Breaking changes without versioning breaks trust.
Custom Validators in Pydantic
Need validation beyond type checking? Pydantic's field_validator and model_validator decorators let you add custom logic. Validate emails, check password strength, whatever you need.
Pagination: Don't Return Everything
Returning 10,000 records in one response? Please don't. Implement pagination with limit and offset (or better, cursor-based). Your database and clients will be happier.
