Is it possible to point to a folder containing the packages instead? I noticed every package installed is cached locally and since I'm usually reinstalling the same packages it would be great if I could point to a folder and let npm install packages and their dependencies from there. Extra points if it could fallback to the official registry if it fails to find a package in the local folder.
