#Error management in gulp

Sucking at something is the first step to becoming sorta good at something

No one can assure you, that plugins will run smooth in any circumstances (except for tests - they could), so neither should you convince anyone, that your plugin will never break. Only thing, that you could possibly do (if something gone wrong) - is gracefully inform your plugin user, that something went wrong and die.

We are will use this plugin from beginning to demonstrate error management. Suppose you have a task in gulpfile.js that contains this code (we modified it a little bit to be closer to real-usage):

var coffee = require('gulp-coffee');
