GULP

danielfisher.com

What is Gulp?• A node.js Task Runner– Most contributions by

Eric Schoffstall (contra)– Grunt plug-ins often perform n tasks

• Gulp plug-ins are designed to do only thing.

– Grunt requires plug-ins for basics• Gulp has them built-in.

– Grunt uses JSON-like data configuration files • Gulp uses leaner, simpler JavaScript code.
