debug-callback

debug-callback outputs outstanding callbacks, results, errors, and call times and makes state dumps showing all callbacks that have not yet been called.

How?

var q = require('q');
var debug = require('debug-callback')('test-logger');
var cb = debug(function () {
 
}, 'arbitrary cb name for logging');
 
// sometime in the future call that callback
setTimeout(cb, 10000);
