arupex-logger

Generic logger that operates in both a JSON format and a Easy to read Dev format but is also extendable

Description:

This is the logging framework that npm arupex uses

Main feature

process.NODE_ENV === 'production' || 'prod'

Uses a prod formatter which formats logs in JSON so splunk and other aggregators can read your logs easily

• IE:

   {
       "timestamp":"2018-03-19T21:18:54.023+00:00",
       "logger_name":"Prod Logger",
       "level":"info",
       "log_line":"    at traceRoute (/Users/daniel.irwin/git/arupex-logger/Logger.js:21:20)",
       "message":"quick test"
   }

Otherwise a dev formatter is used to keep your console clean, but also give you timestamps, and tracing information

• IE:

  19:37:21 Dev Logger info     at traceRoute  | Logger.js:21:20 quick test
