// More info here: https://github.com/flatiron/winston

// Simple Example
var winston = require('winston')
var mongoTransport = require('winston-mongodb').MongoDB

defaultLogger.level = 'silly' 
defaultLogger.silly("Default logger")

// Complex Example
var logger = new winston.Logger({
    transports: [
      new winston.transports.Console({ level: 'debug', colorize: true }),
      new winston.transports.File({ filename: 'winston.log', json: false }),
      new mongoTransport({ db: 'winston' }) // Default ({ collection: 'log', host: 'localhost', port: 27017})
      //new winston.transports.Redis() // Default: ({ host: 'localhost', port: 6379, auth: 'None' })
    ],
    colors: [{
      info: 'blue',
      warn: 'yellow',
      error: 'red'

logger.info(logger.levels)
logger.info("Hello", { metadata: "metadata" })
