Update February 2015: this post is now out of date as the starter kit has evolved. I’m working on a new post to explain all the developments; in the meantime please check out the original repo on GitHub. Thanks!
WordPress theme development is remarkably more efficient with Gulp, a Node-based build system and task runner similar to Grunt. Gulp has been widely hyped in recent times—and no wonder, it’s a major time-saver. I found out about Gulp by way of this excellent introduction by Mark Goodyear, later adapting the build script in this post by Matt Banks for my own use.
Since then I have refined my workflow to the point where I figure it might be helpful for me to share my approach with the WordPress community. With this in mind I have prepared this starter kit (with source code on GitHub) to demonstrate how you can use Gulp with Bower and Sass to optimize your WordPress theme development workflow. This starter kit does not contain any actual WordPress theme files—it is meant to act as the scaffolding that surrounds your theme and supports your workflow.
