How to start a Django project in 2012

(and deploy to Heroku)

First, warm up your system.

###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.

	Create a virtualenvs directory to store all virtual environments
	$ mkdir somewhere/virtualenvs

	Make a new virtual environment with no packages
