A tiny stream log

Install

$ npm install --save squeak

Usage

var Squeak = require('squeak');
var log = new Squeak()
	.type('info')
	.type('success', {color: 'green'})
	.type('warn', {color: 'yellow'})
	.type('error', {color: 'red'}, function () {
		log.end();
		process.exit(1);
	});

log.info('this is a info message');
log.success('this is a success message');
log.warn('this is a warning');
log.error(new Error('this is an error').stack);

/*
     info : this is a info message
  success : this is a success message
     warn : this is a warning
    error : this is an error
    at ChildProcess.exithandler (child_process.js:648:15)
    at ChildProcess.emit (events.js:98:17)
 */

You can also customize the different types to use a custom prefix using the prefix option:

var Squeak = require('squeak');
var log = new Squeak({separator: ' '})
	.type('success', {color: 'green', prefix: '✔'})
	.type('warn', {color: 'yellow', prefix: '⚠'});

log.success('this is a success message');
log.warn('this is a warning');

/*
  ✔ this is a success message
  ⚠ this is a warning
 */
