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
*/
