Sounds like a silly question but i just don’t get it :
When i download cakephp from Github, my cakephp src directory is full (ORM/, Auth/, etc) but when i use composer (and the bake), the src directory is pretty light (only 6 directories).
My app is still working so i don’t get it
By “using composer”, I assume you mean composer create-project cakephp/app? That is because that uses the cakephp application skeleton (https://github.com/cakephp/app). Composer downloads the actual CakePHP framework code into the vendor/ directory.
