Make it easier to debug with logging levels.

level-debug

I don't think you need this library. Make it easier to debug with logging levels.

Usage

Example:

import { levelDebug, withLevel, Level } from 'level-debug'

const log = levelDebug('module:function')

require('debug').enable('*')
log.debug('...') // module:function:debug ... +0ms
log.info('...') // module:function:info ... +0ms
log.warn('...') // module:function:warn ... +0ms
log.error('...') // module:function:error ... +0ms
log.fatal('...') // module:function:fatal ... +0ms

require('debug').enable(withLevel('module:function', Level.WARN))
log.debug('...') //
log.info('...') //
log.warn('...') // module:function:warn ... +0ms
log.error('...') // module:function:error ... +0ms
log.fatal('...') // module:function:fatal ... +0ms

withLevel expands namespaces with level:

Namespaces	withLevel	Output
*	WARN	*:warn,*:error,*:fatal
ns	WARN	ns:warn,ns:error,ns:fatal
-*	Not used	-*
-ns*	Not used	-ns*
-*ns	Not used	-*ns:debug,-*ns:info,-*ns:warn,-*ns:error,-*ns:fatal
