Peer Dependenciesnpm is awesome as a package manager. In particular, it handles sub-dependencies very well: if my package depends on request version 2 and some-other-library, but some-other-library depends on request version 1, the resulting dependency graph looks like: ├── request@2.12.0 └─┬ some-other-library@1.2.3 └── request@1.9.9 This is, generally, great: now some-other-library has its own copy of request v1
