(Yii2) What are Modules used for?

Question

Yii

I've read the Modules Guide , but I can't figure out when to use them.

Answer 1

The same gii is a module.
That is, it is a separate part of the site. For example, you don’t need to write a forum, but you can search for an existing one and put it in a separate folder, and not scatter it throughout the project - controllers there, models here...
