node-depugger

Depugger is a small lib that provides a debugging utility.

Installation

$ npm install depugger

depugger([debug, [name]]), depugger(options)

depugger returns a function that supports all of the util.format features and outputs debug messages based on the initial configuration.

• debug: specifies if logged messages should be outputted, optional, default: false
• name: a category key that will prepend every message, optional, default: ""
• options: options hash that can be used to submit all of the above parameters at once

var depugger = require('depugger');
 
var debug = depugger(true, 'fooDebugger');
 
debug('foo');
debug('bar "%s"', 'bax');
debug('spam %d eggs', 10);
 
//output to console:
//[fooDebugger] foo
//[fooDebugger] bar "bax"
//[fooDebugger] spam 10 eggs

Alternatively all parameters can be specified via an options hash:

var depugger = require('depugger');
 
var debug = depugger({debug: true, name: 'fooDebugger'});
 
debug('foo');
debug('bar "%s"', 'bax');
debug('spam %d eggs', 10);
 
//output to console:
//[fooDebugger] foo
//[fooDebugger] bar "bax"
//[fooDebugger] spam 10 eggs
 

depugger.child(childName)

Creates a child instance. The name of the parent's debugger will be concatenated with the childDebugger's name:

var depugger = require('depugger');
 
var debug = depugger({debug: true, name: 'fooDebugger'});
 
var childDebug = debug.child('child');
 
childDebug('foo');
 
//output to console:
//[fooDebugger.child] foo
