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
