debug-levels-promise v0.0.2

debug-levels

Although debug-levels is not async and thus doesn't need to be promisified, I wanted to be able to callback only when a certain debug level applies and decided to use the Promise notion.

Installation:

npm install debug-levels-promise

Example Usage:

// Using DEBUG=*;DEBUG_LEVEL=debug
const debug = require('debug-levels-promise')('example');

debug('first')
    .then(()=>debug('...second'));

debug
    .log('log!')
    .then(() => debug('...log callback'));

debug.error('error!');

debug.warn('warn!')
    .then(args => debug('...warn callback', args));

debug.debug('debug!'); //debug level threshold

debug
    .info('info!')
    .then(_ => debug('...info callback')); //won't fire

debug.verbose('verbose!');

// debug:example first +0ms
// debug:example log! +1ms
// debug:example error! +0ms
// debug:example warn! +0ms
// debug:example debug! +0ms
// debug:example ...second +1ms
// debug:example ...log callback +0ms
// debug:example ...warn callback { '0': 'warn!' } +0ms
