Basic CRUD seems like the starting point for just about any db driven web app. Found there wasn't much available for node.js. So here is a first go.

INSTALLATION Get node.js, npm and mongdb

npm install mongoose
npm install jade
npm install express

SETTING UP Start mongodb in the terminal. Navigate to your mongodb install directory which should be something like..

/Users/Username/src/mongodb-osx-x86_64-1.8.3/bin 

and run

mongod

There are probably better ways, I don't know them. In another terminal cd into the crud-mongo-express directory and run

node index.js

In a browser go to

http://localhost:3000/posts/
