# Middleware Avançado

No tutorial principal você leu como adicionar [Middleware Personalizado](../tutorial/middleware.md){.internal-link target=_blank} à sua aplicação.

E então você também leu como lidar com [CORS com o `CORSMiddleware`](../tutorial/cors.md){.internal-link target=_blank}.

Nesta seção, veremos como usar outros middlewares.
