As you and your crush are busy not letting anyone get in front of you and take your burgers whenever they arrive, you cannot pay attention to your crush. 😞

# Behind a Proxy { #behind-a-proxy }

In many situations, you would use a **proxy** like Traefik or Nginx in front of your FastAPI app.

These proxies could handle HTTPS certificates and other things.

Você pode usar a mesma técnica para estender o JSON Schema e adicionar suas próprias informações extras personalizadas.

Por exemplo, você poderia usá-la para adicionar metadados para uma interface de usuário de front-end, etc.

/// info | Informação

O OpenAPI 3.1.0 (usado desde o FastAPI 0.99.0) adicionou suporte a `examples`, que faz parte do padrão **JSON Schema**.

Você também pode usá-lo para gerar código automaticamente para clientes que se comunicam com sua API. Por exemplo, aplicativos front-end, móveis ou IoT.

### Faça o deploy da sua aplicação (opcional) { #deploy-your-app-optional }

With respect to development inside an IDE the workspace from which we would like to resolve and retrieve dependencies is a read-only local repository to Mercury which is put at the front-end of the search order of any repository that Mercury will consult for artifacts.
