为什么我不能使用 Django 服务器进行生产？

Question

I'm learning Django for the first time and I'm also relatively new to Python. On the Django documentation , it says,

"You've started the Django development server, a lightweight Web server written purely in Python. [...] don't use this server in anything resembling a production environment. It's intended only for use while developing."

Why shouldn't I use the Django server for production? Why do I need a separate server? I'm from a Node/Express background, and when I created an Express application, I could just deploy it to Heroku without doing too much. How will this be different for Django?

Answer 1

Because of security and performance reasons. It's only meant to be used while developing.
