Dumb Logger

A simple logger for nodejs. Adds colorization, code location, and timestamps. Configurable by module name using environment variables.

const log = require('logger')()

log.debug('debug')
log.info('info')
log.verbose('verbose')
log.notice('notice')
log.warn('warn')
log.error('error')
log.crit('crit')
log.alert('alert')
log.emerg('emerg')

yields:

Works the same way you'd expect console.log, pass in as many args as you want

log.info([1, 2, "three"], "string", { my: "object" })

Log Levels

EMERG:   0
ALERT:   1
CRIT:    2
ERROR:   3
WARN:    4
NOTICE:  5
VERBOSE: 6
INFO:    6  // intentional, verbose and info are aliases of each other
DEBUG:   7

Configuration

Logger user environment variables to determine the log levels. By default, the log level is set to 'INFO'.

$ export LOG_LEVEL_MYMODULE=WARN
$ export DEFAULT_LOG_LEVEL=INFO

Environment variables are prefixed with LOGLEVEL and then an uppercase and underscored tag. So to set log level of DEBUG for ./any/path/my-module.js.asdfljk (extensions are ignored), you would do:

$ export LOG_LEVEL_MY_MODULE=DEBUG
