## Recursos do Starlette

**FastAPI** é totalmente compatível com (e baseado no) <a href="https://www.starlette.io/" class="external-link" target="_blank"><strong>Starlette</strong></a>. Então, qualquer código adicional Starlette que você tiver, também funcionará.

`FastAPI` é na verdade uma sub-classe do `Starlette`. Então, se você já conhece ou usa Starlette, a maioria das funcionalidades se comportará da mesma forma.
