For production you would use `fastapi run` instead. 🚀

Internally, **FastAPI CLI** uses <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, a high-performance, production-ready, ASGI server. 😎

## `fastapi dev`

Running `fastapi dev` initiates development mode.

// A simple in-out test: Do we print what we parse?

func setArch(goarch string) (*arch.Arch, *obj.Link) {

Mas por enquanto, vamos verificar essas importantes **ideias conceituais**. Esses conceitos também se aplicam a qualquer outro tipo de API da web. 💡

## Segurança - HTTPS

No [capítulo anterior sobre HTTPS](https.md){.internal-link target=_blank} aprendemos como o HTTPS fornece criptografia para sua API.

Também vimos que o HTTPS normalmente é fornecido por um componente **externo** ao seu servidor de aplicativos, um **Proxy de terminação TLS**.
