Specifying dependencies in Node.js

• Put a package.json file in the root of your project
• List your deps in that file

  { "name" : "my-project"
  , "version" : "1.0.0"
  , "dependencies" : { "express" : "1.0.0" } }
  

• npm install Since you're calling this with no args, and not in global mode, it'll just install all your deps locally.

• require("express")
