Package

Express has package manage system like Gem in Ruby.
All packages are written in package.json on your project root.

Example

{
  "name": "People",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "body-parser": "~1.10.2",
    "cookie-parser": "~1.3.3",
    "debug": "~2.1.1",
    "ejs": "~2.2.3",
    "express": "~4.11.1",
    "morgan": "~1.5.1",
    "serve-favicon": "~2.2.0",
    "mongoose" : "*",
    "passport" : "*",
    "passport-local" : "*",
    "connect-flash": "*",
    "bcrypt": "*",
    "express-session" : "*",
    "multer" : "*",
    "app-root-path" : "*",
    "node-uuid": "*",
    "aws-sdk": "*"
  },
  "devDependencies": {
    "grunt": "*"
  }

dependencies are for main project. devDependencies are for development
