Testing setup

Preparing for heroku

add to server.js

  const port = process.env.PORT || 3000;

  app.listen(port, () => {
    console.log(`running on ${port}`); 
  });

add to package.json with node -v on current maching

  "engines": {
    "node": "6.9.3"
  },

heroku also needs to know how to start the app

  "start": "node server/server.js",

Set up heroku database

$ heroku create

$ heroku addons:create mongolab:sandbox

$ heroku config (gives access to MONGODB_URI)

  mongoose.connect(process.env.MONGODB_URI || <dev connection>)

$ git push

$ git push heroku master

$ heroku logs

$ heroku open

create Config file

add to package.json

  "test": "export NODE_ENV=test || SET \"NODE_ENV=test\" && mocha server/**/*.tests.js",

add to config/config

  var env = process.env.NODE_ENV || 'development';

  if (env === 'development) {
    process.env.PORT = 3000;
    process.env.NODE_ENV = 'mongodb://localhost:27017/TodoApp';
  } else if (env === 'test') {
    process.env.PORT = 3000;
    process.env.NODE_ENV = 'mongodb://localhost:27017/TodoAppTest';
  }
