###Creating a REST API using Node.js, Express, and MongoDB

####Installing Node.js

Go to http://nodejs.org, and click the Install button. Run the installer that you just downloaded. When the installer completes, a message indicates that Node was installed at /usr/local/bin/node and npm was installed at /usr/local/bin/npm. At this point node.js is ready to use. Let’s implement the webserver application from the nodejs.org home page. We will use it as a starting point for our project: a RESTful API to access data (retrieve, create, update, delete) in a wine cellar database.

Create a folder named nodecellar anywhere on your file system. In the wincellar folder, create a file named server.js.

Generators vs Fibers

Both ES6 generators and node-fibers can be used to block a coroutine while waiting on some I/O without blocking the entire process. Both can do this for arbitrarily deep call stacks. The main difference between the capabilities of the two is how explicit the syntax is.

Generators - Safe, but Explicit

In code that uses ES6 generators:

var run = require('gen-run'); // https://github.com/creationix/gen-run
