## Abhängigkeiten { #dependencies }

FastAPI hängt von Pydantic und Starlette ab.

### `standard`-Abhängigkeiten { #standard-dependencies }

Wenn Sie FastAPI mit `pip install "fastapi[standard]"` installieren, kommt es mit der `standard`-Gruppe optionaler Abhängigkeiten:

Verwendet von Pydantic:

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. We still import `field` from standard `dataclasses`.

2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`.
