const logger = bunyanMongoDbLogger({
  name: 'some-name',
  streams: ['stdout', 'mongodb'],
  url: 'mongodb://localhost/logger-test',
  level: process.env.LOG_LEVEL || config.logger.level

module.exports = logger({

and then use logger in your code:

const logger = require('path-to-you-app/lib/logger');

logger.error(new Error('some error'), 'some custom message');
logger.info('Some info');
