Colorlog.js

Light-weight color logging for NodeJS, including a streaming log reader.

Installation

$ npm install colorlog

Example

Colorlog level defaults to DEBUG however here we can specify another level, for example WARNING, and just watch logs levels are >= from WARNING.

var Colorlog = require('colorlog')
  , colorlog = new Colorlog('debug');

colorlog.debug('debug message');
colorlog.info('info message');
colorlog.error('failed to something');

Also possible to use %s much like console.log() to pass arguments:

 colorlog.info('hello from user %s.', user.email);
