Logging to LogDNA Through Bunyan

This module provides an interface that can be hooked into Bunyan and used as a transport to LogDNA. Since @logdna/logger is also an EventEmitter, please make use of the reemitErrorEvents provided by Bunyan so that the implementor can be aware of errors in the LogDNA client. Not doing so will cause Bunyan to throw if @logdna/logger emits an 'error'.

const {createLogger} = require('bunyan')
const LogDNAStream = require('logdna-bunyan')

const logDNA = new LogDNAStream({
  key: apikey
}) // See @logdna/logger for more constructor options

const logger = createLogger({
  name: "My Application"
, streams: [
    {
      stream: process.stdout
    }
  , {
      stream: logDNA
    , type: 'raw'
    , reemitErrorEvents: true // Bubble up 'error' events from @logdna/logger
    }
  ]
})

logger.info('Starting application on port %d', app.get('port'))

NOTE: You must use the raw stream type, and also reemitErrorEvents must be true. Otherwise, errors emitted by @logdna/logger will throw Bunyan.
