Aquí hay un poquito de esa historia.

## Alternativas { #alternatives }

He estado creando APIs con requisitos complejos durante varios años (Machine Learning, sistemas distribuidos, trabajos asíncronos, bases de datos NoSQL, etc.), liderando varios equipos de desarrolladores.

# Usando Dataclasses { #using-dataclasses }

FastAPI está construido sobre **Pydantic**, y te he estado mostrando cómo usar modelos de Pydantic para declarar requests y responses.

Pero FastAPI también soporta el uso de [`dataclasses`](https://docs.python.org/3/library/dataclasses.html) de la misma manera:

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

## Introducción { #intro }

**FastAPI** no existiría si no fuera por el trabajo previo de otros.

Se han creado muchas herramientas antes que han ayudado a inspirar su creación.

He estado evitando la creación de un nuevo framework durante varios años. Primero intenté resolver todas las funcionalidades cubiertas por **FastAPI** usando muchos frameworks diferentes, plug-ins y herramientas.
