Refactoring

+ R1: A good test suite increases confidence that code changes won't cause 
+ unexpected side effects without being noticed.

+ R2: Tests reduce the cost of structural changes in later stages of a project 
+ because fewer bugs sneak into a system unnoticed.

- R3: Brittle tests can increase the cost of refactoring if they focus on 

Deploying a node app with Forever is great...until your server restarts unexpectedly. Then your app stops running and you have to re-deploy.

To get around this, we're going to run our node app as an Upstart service. Upstart services are great, because, once started, the system auto-restarts them if they fail, or if the server restarts.

###Step 1: Create a service for your node app

  • ssh in as root ssh root@youripaddress
  • Create a node-app.conf file in /etc/init
    IMPORTANT: whatever filename you pick is what you will use to start|stop|restart your service i.e. service node-app start

##Setup your server (this would ideally be done with automated provisioning)

  • add a deploy user with password-less ssh see this gist
  • install forever npm install -g forever

##Install flightplan

  • npm install -g flightplan
  • in your project folder npm install flightplan --save-dev
  • create a flightplan.js file
