title: Possible to install all missing modules for a node application?
body: <p>I have a node app that I just started working with and each time I try to run it, it says there is a missing module.  I've just been using <code>npm install ...</code> for each module but after doing about 10 of them I'm wondering if there is a way to have npm pull down all needed modules for a node app without me installing each one manually.  Can it be done?</p>
