Declare dependencies with NPM /package.json

# /package.json
{
  "name": "application-name",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app"
  },
  "dependencies": {
    "express": "3.0.0rc4",
    "jade": "*"
  },
  "engines": {
    "node": "0.8.x",
    "npm": "1.1.x"
  } 
}

Install your dependencies (-l 處理相依性)

$ sudo npm install -l

Declare process types with Procfile

# create '/Procfile'
web: node app.js

# test start
$ foreman start

Git

$ git init
$ git add .
$ git commit -m "init"
