Debug extend

Extends debug with verbosity levels. Compatible in browser also.

//Require this only one time in your entry file
require('debug-extend')

//Require debug as usual
const debug = require('debug')('app')

debug.verbose('logtrace5') // VERBOSE Level 5
debug('logtrace4')         // DEBUG Level 4
debug.info('logtrace3')    // INFO Level 3
debug.warn('logtrace2')    // WARN Level 2
debug.error('logtrace1')   // ERROR Level 1

Output

$ DEBUG=app node index.js
app VERBOSE logtrace5 +0ms
app logtrace4 +0ms
app INFO logtrace3 +0ms
app WARN logtrace2 +0ms
app ERROR logtrace1 +0ms

Level filtering

You can filter your output debugs with:

const Debug = require('debug')
Debug.level(4)

or by environment variable DEBUG_LEVEL

DEBUG_LEVEL=4 node index.js

or using localStorage when in browser

localStorage.setItem('debug-level',4)

To disable all output just use level 0
