## Instala el Programa del Servidor { #install-the-server-program }

Cuando instalas FastAPI, viene con un servidor de producción, Uvicorn, y puedes iniciarlo con el comando `fastapi run`.

Pero también puedes instalar un servidor ASGI manualmente.

Asegúrate de crear un [entorno virtual](../virtual-environments.md), actívalo, y luego puedes instalar la aplicación del servidor.

Por ejemplo, para instalar Uvicorn:

"%GOBIN%\go" clean...

func setPutObjHeaders(w http.ResponseWriter, objInfo ObjectInfo, del bool, h http.Header) {
	// We must not use the http.Header().Set method here because some (broken)
	// clients expect the ETag header key to be literally "ETag" - not "Etag" (case-sensitive).
	// Therefore, we have to set the ETag directly as map entry.
	if objInfo.ETag != "" && !del {
		w.Header()[xhttp.ETag] = []string{`"` + objInfo.ETag + `"`}
	}

		}
	}
	itemKeys := store.List()
	// Remove all the items.
	if len(itemKeys) == 20 {
		for _, key := range itemKeys {
			err := store.Del(key)
			if err != nil {
				t.Fatal("queue store Del failed with ", err)
			}
		}
	} else {
		t.Fatalf("List() Expected: 20, got %d", len(itemKeys))
	}

	keys := store.List()
	if len(keys) != 0 {

<summary>Acerca del comando <code>fastapi dev</code>...</summary>

El comando `fastapi dev` lee tu archivo `main.py` automáticamente, detecta la app **FastAPI** en él y arranca un servidor usando [Uvicorn](https://www.uvicorn.dev).

Por defecto, `fastapi dev` comenzará con auto-recarga habilitada para el desarrollo local.
