uLogger

Tiny logger utility for Node.JS and the browser

Usage

 
var logger = require('ulogger')('my-unit');
 
logger.log('A message inside my unit');
logger.error('Oops, my unit has an error!');
 

Enable/disable

In your app code, you can enable/disable the logger at any moment:

 
var logger = require('ulogger')
logger.enable();
 
// ...
 
logger.disable();
 

On Node.JS, you can start your app with an environment flag:

DEBUG=1 node my-app.js

Same goes for a web app, but in the window object:

window.DEBUG=1;

Log levels

You can adjust the logging level from error to debug. The log whose values are higher than the level won't be printed.

// 0 = error
// 1 = warn
// 2 = info
// 3 = log
// 4 = debug
 
var level = 2;
logger.logLevel(level);
 
// only error, warn and info logs will be printed from now on
 

Happy debugging!
