Answer 1

It's new npm 3.* feature. From npm blog:

With npm@3, your node_modules directory will be a lot flatter. All of your dependencies and most of your subdependencies (and (sub)+dependencies) will be sitting next to each other at the top level. Only when there are conflicts will modules be installed at deeper levels. This should make things a lot easier for Windows users.
