#bunyan-pretty James Wyse's workaround for getting pretty-printed bunyan output in Node. See trentm/node-bunyan#13 for details.

You could use it like this:

var bunyanPretty = require('bunyan-pretty');
bunyan.createLogger({
  name: 'audit',
  stream: process.stdout.isTTY ? bunyanPretty() : process.stdout,
  level: 'info'
})
