Only works with Node.js version higher than 0.11.3 (see blog post linked below to see how to setup multiple node versions)
To install: npm install
To start the app a special flag is required: node --harmony-generators ./app.js
The book collection used in the example is available in the sw.json file. The code assumes that the database name is starwars and the collection is books - henceforth to import the JSON file execute the following (alter if necessary):
mongoimport --db starwars --collection books --file sw.json
