BackboneJS Boilerplate with RequireJS NodeJS Express and MongoDB
Download nodejs - http://nodejs.org
Install express Open your command prompt or terminal window, change your directory to the folder of your application and type: npm install express
Install socket.io - npm install socket.io
Install mongoDB for windows - http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/
Install mongodb for OSX - http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/
docs.mongodb.org also has a number of other installation and getting started guides
Once everything is installed, you will need to start the mongodb and the node server. To do this I open 2 command prompt/terminal windows and:
In the first window type:
cd path-to-your-folder\mongodb\bin
mongod
In the second window type:
cd path-to-your-folder
node server
