FastHTML Best Practices: Cleaner Code, Smarter Defaults, Simpler Routes

FastHTML best practices emphasize simplicity, smart defaults, and idiomatic patterns for efficient web development.

From Hacker News Original Article Hacker News Discussion

FastHTML is a Python web framework that emphasizes simplicity, smart defaults, and concise, clear code, differing from frameworks like FastAPI or Django. It encourages idiomatic practices such as using dataclass-style table definitions, query parameters, and leveraging return values for cleaner and more maintainable code.

Why it matters: FastHTML reduces boilerplate and complexity, enabling faster development with straightforward, Pythonic conventions.

The big picture: It integrates semantic HTML styled by PicoCSS by default and promotes minimal, functional patterns for building web apps efficiently.

The other side: Some users prefer more explicit, declarative styles or established ORMs and question certain design choices like always using POST for mutations.

Commenters say: Users appreciate FastHTML's simplicity, fast iteration, and minimal tooling, though some find documentation inconsistent and debate trade-offs in design decisions.
