FastAPI has been constantly growing in popularity during the last years. A lot of this growth is driven by its relative simplicity and ease-of-use.

We'll explore how FastAPI's core features like Pydantic integration and dependency injection can improve API development, while also talking about the drawbacks of FastAPI.
