What is gulp? According to their homepage gulpjs.com, it's a toolkit to automate & enhance your workflow. What exactly does that mean? Well, for medium to large-sized projects you may want to have a folder with all your styles and scripts minified. This can significantly decrease file sizes and is usually best practice when deploying your app. Gulp can do all the hard work for you. It can throw all your final code into a new folder, minify it, and even add extra things to make your code even better!
You can follow along on Treehouse Blog where I take you through setting up a basic gulpfile for your own projects and apps. Once we're done, you should have a clear understanding of how gulp works as well as add even more features to make your gulpfile even more powerful. If at anytime you need to check the source code, be sure to refer back to this repo.
