Si usas o planeas usar Clawdbot/OpenClaw (o el nombre que termine teniendo la próxima semana), échale un vistazo a este video (youtu.be/QFhDB3UEFm8?...), súper recomendado. La seguridad es lo primordial, por encima de todo. Es una herramienta excelente y le tengo muchísimo hype.

And what if we rewrote Express in Rust?

Congratulations!
