As of Npm version 1.1.2 , there's a new command npm shrinkwrap which creates an npm-shrinkwrapped.json file, analogous to Gemfile.lock. It's important to make one, to prevent software rot (see Bundler's rationale). Particularly as Nodejs has such a fast moving community.

While bundle install creates a Gemfile.lock automatically, npm install won't create npm-shrinkwrapped.json (but will use it when it exists). Hence you need to remember to use npm shrinkwrap.
