MongoDB initializer for app-context

Usage

This initializer can be auto-installed by using it in your context file.

This initializer will attach the configured connections to APP.mongodb.

module.exports = function() {
  this.runlevel('connected')
    // attach a connection to APP.mongodb - use the value at APP.config.mongodb as the connection string
    .use('mongodb', '$mongodb')

    // attach a connection to APP.mongodb
    .use('mongodb', 'mongodb://localhost/foobar')

    // create 2 connections and attach them as an object to APP.mongodb
    // this will create APP.mongodb.users and APP.mongodb.data
    .use('mongodb', {
      users: '$mongodb.users',
      data: '$mongodb.data'
    })

    // you can also pass options to each connection
    // (from http://mongodb.github.io/node-mongodb-native/2.0/api/MongoClient.html#.connect)
    .use('mongodb', {
      users: {url: '$mongodb.users', db: {
        wtimeout: 2000,
        authSource: 'other-db'
      }},
      data: {url: 'mongodb://localhost/data', server: {
        reconnectTries: 2,
        reconnectInterval: 500
      }}
    })
};

Connection Strings

Connection string formats and options are available in the mongodb driver docs.

Connection Configurations

Each connection can be configured with either a connection string (like mongodb://localhost/foobar) or with an object. The object will be passed through to MongoClient.connect and can consist of any options from the mongodb driver. There is a special url option that this initializer requires.
