CodeIgniter4 Modular Structure Application Starter

With CI4, I think this is not necessary.
Simple can sub folder or https://codeigniter.com/user_guide/gener..._apps.html
...
CI3 + HMVC + ... + = CI4

Hi NC, for me, this is not the same, separate apps does not share anything.

I have found that I need share common libaries, helpers, languages, but also there are specific parts of a project that I like to be isolated, but with all components inside the same structure.

This is only an example of how can be done with subfolders as you say.

Also, I have old apps in CI3 that give me the possibility to migrated them to CI4 with few code changes.

The beter of CI4 is that you can choose the structure that better fits to your needs !!
