usage

add an event logger to the mongoose db connection for each event type you want to log. the event logger will default to using the console to log events, however, you can optionally pass in your own logging service.

the log message is composed using new Date() and the db connection info; e.g. [info] %date connected to mongodb://%host:%port/%database

basic

var createEventLogger = require( 'mongoose-events-event-logger' )
var db

db = mongoose.connection
db.on( 'connected', createEventLogger( 'connected', db ) )

with a custom logger

var eventLogger = require( 'mongoose-events-event-logger' )
var db

// logging service needs to have a .log( arg1[, arg2[, ...] ] ) method
var logger = require( 'your-custom-logger' )

db = mongoose.connection
db.on( 'connected', createEventLogger( 'connected', db, logger ) )
