this is a mirror of http://blog.ksetyadi.com/2011/10/nodejs-and-mongodb-a-beginners-approach/

This is not a book and I didn’t try to sell a book to you.

The term “A Beginner’s Approach” reflects my self when finding a hard way out to connect Nodejs to MongoDB. There are lots of libraries available to use when connecting Nodejs to MongoDB. If you were trying to make your feet wet, and that’s what I’m doing until today, you probably want to try this approach. I can’t promise anything but at least, you will not get a headache.

First, read about Nodejs. After that, MongoDB. If you’re already familiar with it, skip it and install both on your system. There maybe vary depending on your system. If you use Mac and Homebrew (or MacPorts), you’re lucky. Just do this:

$ brew install node

  {
     _count = count;

You build an endpoint that takes in data and saves it. 

This is a service that takes in data from outside sources, the user can be any type.

(some sites use integers, some use strings, some guids...)

3 samples:
POST /notes
{
  user: 9000
