I'm new to the whole Composer/dependencies game.
I want to know whether if I create a project using, for example composer require intervention/image from a cmd window opened in the project root folder, the project is then completely portable. Meaning if I copy the project folder on to another machine with no internet, no composer installed and none of the other dependencies installed, will it still work?
Put another way, when I run composer require intervention/image are all of the necessary files cloned locally?
You get a local copy of the files so if you manually copy the project, the vendor directory will go with it. If using Git, typically a .gitignore is set to ignore this dir and you won't get it on clone.
