1) We have our own private npm that can optionally include a caching layer. This has been invaluable since the beginning of our company to manage internal dependencies. 2) We use StriderCD, the self-hosted CD/CI, and it too supports caching node_modules. 2 minutes is a 'long' time for us from git push to autodeploy. 3) We use gulp and npm always. Grunt and bower are a mess. EDIT: Also, we npm shinkwrap projects. It avoids numerous issues and makes module caching a natural part of the process.
