/// warning | Achtung

Uvicorn und andere Server unterstützen eine `--reload`-Option, die während der Entwicklung nützlich ist.

Die `--reload`-Option verbraucht viel mehr Ressourcen, ist instabiler, usw.

Sie hilft während der **Entwicklung**, Sie sollten sie jedoch **nicht** in der **Produktion** verwenden.
