This makes it easy to generate up-to-date **documentation**, client libraries (<abbr title="Software Development Kits">**SDKs**</abbr>) in multiple languages, and **testing** or **automation workflows** that stay in sync with your code.

In this guide, you'll learn how to generate a **TypeScript SDK** for your FastAPI backend.

## Open Source SDK Generators { #open-source-sdk-generators }

### Swagger UI y `examples` específicos de OpenAPI

Ahora, como Swagger UI no soportaba múltiples ejemplos de JSON Schema (a fecha de 2023-08-26), los usuarios no tenían una forma de mostrar múltiples ejemplos en los documentos.

Para resolver eso, FastAPI `0.103.0` **añadió soporte** para declarar el mismo viejo campo **específico de OpenAPI** `examples` con el nuevo parámetro `openapi_examples`. 🤓
