Loggerhythm

A winston-wrapper to log in a debug-like manner including namespaces

Usage

Loggerhythm exports a function, which requires a namespace and returns the logger-class. This class has different log-functions for different log-levels. By default, the avaliable loglevels are:

• critical
• error
• warn
• info
• verbose
• debug
• silly

Example

const logger = require('loggerhythm')('readme-namespace');

logger.info('foo');
logger.warn('bar');

The output would look like this (the different log-leves use different colors):

2016-08-30T14:06:33.751Z - info:     [readme-namespace] foo
2016-08-30T14:06:33.752Z - warn:     [readme-namespace] bar

Methods

alongside the different log-methods you have (within setup) the setLevel-method to tell the module, what the minimal loglevel is a message needs to have to be logged. This setting is global, and will effect all loggers. You also have this method, if you only require loggerhythm, without giving it a namespace, although you cannot use these non-namespaced instances to log things.

const logger = require('loggerhythm')('readme-namespace');

logger.setup.setLevel('warn');
logger.info('foo');
logger.warn('bar');

or

const logger = require('loggerhythm')('readme-namespace');
const someOtherLogger = require('loggerhythm');

someOtherLogger.setup.setLevel('warn');
logger.info('foo');
logger.warn('bar');

will output:

2016-08-30T14:14:48.520Z - warn:     [readme-namespace] bar

Todo

Loggerhythm can not yet log to files, only to the console. It is planned that logs can be stored to files independent of the DEBUG-environment-variable. With that, you could get a complete, persistent log, aswell as the DEBUG-filtered console-output.
