Writable stream that formats bunyan records that are piped into it
var bunyan = require('bunyan')
, bformat = require('bunyan-format')
, formatOut = bformat({ outputMode: 'short' })
;
var log = bunyan.createLogger({ name: 'app', stream: formatOut, level: 'debug' } );
log.info('starting up');
log.debug('things are heating up', { temperature: 80, status: { started: 'yes', overheated: 'no' } });
log.warn('getting a bit hot', { temperature: 120 });
log.error('OOOOHHH it burns!', new Error('temperature: 200'));
log.fatal('I died! Do you know what that means???');- Printing the level in String representation for Json objects
var bunyan = require('bunyan')
, bformat = require('../')
, formatOut = bformat({ outputMode: 'bunyan', levelInString: true })
;The output would use the string levels:
