Log Levels

Mirror that of syslog, but reversing ordering:

• 8 EMERGENCY system unusable
• 7 ALERT immediate action required
• 6 CRITICAL condition critical
• 5 ERROR condition error
• 4 WARNING condition warning
• 3 NOTICE condition normal, but significant
• 2 INFO a purely informational message
• 1 DEBUG debugging information

Use

La libreria permite su invocacion de cuatro formas indistintamente:

• hologger(3, {foo: "bar"}) => la mas completa
• hologger("some custom message") => para mensajes sobre la marcha
• hologger({foo: "bar"}) => igualmente sobre la marcha, pero con info estructurada
• hologger(Error) => logueo de errores

En cualquier caso, se generara un codigo de error que, dependiendo del nivel de logueo tendra la siguiente apariencia.

• emergency; // 8xxxxxxx
• alert; // 7xxxxxxx
• critical; // 6xxxxxxx
• error; // 5xxxxxxx
• warning; // 4xxxxxxx
• notice; // 3xxxxxxx
• info; // 2xxxxxxx
• debug; // 1xxxxxxx

CAVEATS

A fin de facilitar la operativa interna del logger, y de ser capaz de operar de la forma mas abstracta posible en el mayor numero de casos posible, hologger produce la estandarizacion interna del nombre de un numero de contado de propiedades de la informacion que se le presenta a logueo, siendo estas:

• error => err
• request => req

TODO

• Agregar metodo useLibrary para configurar la libreria de codigos a usar (breaking)
