console-log-level

A dead simple logger. Will log to STDOUT or STDERR depending on the
chosen log level. It uses console.info, console.warn and
console.error and hence supports the same API.

Log levels supported: trace, debug, info, warn, error and fatal.


Installation

``
npm install console-log-level
`

Example usage

`js
var log = require('console-log-level')({ level: 'info' })

log.trace('a') // will not do anything
log.debug('b') // will not do anything
log.info('c') // will output 'c\n' on STDOUT
log.warn('d') // will output 'd\n' on STDERR
log.error('e') // will output 'e\n' on STDERR
log.fatal('f') // will output 'f\n' on STDERR
`

`js
var log = require('console-log-level')({
