Bunyan / Pino Logger instance ready to use

Bunyan is really great for debugging purposes but Pino is crazily fast.

Thinking about that this package was created to use Bunyan whenever the LOG_LEVEL environmental variable is set to debug or trace;

INSTALL

npm install em-loger --save

Config

Logr will use bunyan if the LOG_LEVEL environmental variable has the values trace or debug and it will also enable the src option of bunyan automatically, which displays the filename along side with the line number on each log message.

Using LOG_LEVEL environmental variable with the values info, warn or trace will load pinojs which is faster and has a very similar api.

USAGE

    const logr = require('em-logr');
    
    logr.trace('My trace message');
    logr.debug('My debug message');
    logr.info('My info message');
    logr.warn('My warn message')
    logr.error('My error message');

Child loggers

    const 
      _1stChildLogr = require('em-logr').child({name:'1stChild'}),
      _2ndChildLogr = require('em-logr').child({name:'2ndChild'});
 
    _1stChildLogr.info("The remote is mine, I am the first born child");
    _2ndChildLogr.info("The remote is mine, Mom likes me better");
    _1stChildLogr.warn("Get out of here or I'll hit you in the face!");
    _2ndChildLogr.info("Do not touch me or I'll tell mom to know about  secret.");
    _1stChildLogr.error("I did' see that coming!");
