@firstfleet/ffsyslog v1.0.14

winston-syslog

A Syslog transport for winston. This is a fork of winston-syslog. Have added colors for different log levels and better message formatting for use with papertrail. Feel free to to use this and clean it up if you want.

const winston = require('winston');
require('@firstfleet/ffsyslog').Syslog;

This logger accepts the same options as winston-syslog

const transport = new winston.transports.Syslog(options);

winston.add(transport) || winston.createLogger({transports[transport]})

Magic sauce the formats and colors message. Uses ansi-colors npm package.
