This directory contains runnable sample mongoose programs.

To run:

• first install Node.js
• from the root of the project, execute npm install -d
• in the example directory, run npm install -d
• from the command line, execute: node example.js, replacing "example.js" with the name of a program.

• lean queries
• statics
• methods and statics on subdocs
• custom types
• querybuilder
• promises
• accessing driver collection, db
• connecting to replica sets
• connecting to sharded clusters

• aggregation
• advanced hooks
• using $elemMatch to return a subset of an array
• query casting
