Para produção você usaria `fastapi run` no lugar. 🚀

Internamente, **FastAPI CLI** usa <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, um servidor ASGI de alta performance e pronto para produção. 😎

## `fastapi dev`

Quando você roda `fastapi dev`, isso vai executar em modo de desenvolvimento.

# Response - Cambiar el Status Code

Probablemente ya has leído con anterioridad que puedes establecer un [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank} por defecto.

Pero en algunos casos necesitas retornar un status code diferente al predeterminado.

## Casos de uso

Por ejemplo, imagina que quieres retornar un HTTP status code de "OK" `200` por defecto.

		"Total number of messages that failed to send since start",
		targetID)
	auditTargetQueueLengthMD = NewGaugeMD(auditTargetQueueLength,
		"Number of unsent messages in queue for target",
		targetID)
	auditTotalMessagesMD = NewCounterMD(auditTotalMessages,
		"Total number of messages sent since start",
		targetID)
)

// loadAuditMetrics - `MetricsLoaderFn` for audit

  # and print the last word from each
  awk '/Streaming build results to/ {print $NF}' "$TFCI_OUTPUT_DIR/script.log" | uniq
}

# Print out any ResultStore URLs for Bazel invocations' results.
# Each failed target there will have its own representation, making failures
# easier to find and read.
function resultstore_extract {
  local PYTHON_BIN XML_PATH
  PYTHON_BIN=$(which python3 2>/dev/null || which python)
