How to enable extensions in Yii2 without using composer ?
PS Especially for smart people who like to show off, the question is not "do I need to connect extensions without the help of composer" but " How
to connect extensions without the help of composer". and all.

Answer 1

And yet, the easiest way is to do everything that is required with the help of composer, and then copy it to where it is impossible.
UPD: I noticed "own extensions", meaning that you have your own developments, but you don't want to post them in the public domain? Then you can get confused with closed turnips or a cheaper option - just copy the extension to the appropriate folder in the project and that's it, use it. For example, you have a MyComponent component, then you copy it to the frontend/components/ folder and call it through \frontend\components\MyComponent, do not forget to put the correct namespace in the component files
