I usually prefer to place config files in the web directory. And leave the lib directory only for classes.
But I'm currently using SASS and Angular2 in my projects and SASS can not access web/ files from lib/. So I was forced to place config files in lib/. But I don't like that.
Is it a good idea to place config files in the lib directory? What do you prefer to do?
Thanks and sorry my basic English :)
