My gulp script allowed me to write in SASS and have the CSS outputted post processed and minified for production. It optimized the size of all images and re-encoded them only for production (as to not update the original image files). However, the most useful and time saving function my gulp setup offered for this project was browser sync. Setting up browser sync to work with the gulp watch function gave me the ability to compile all changes to styles, js and markup and have the browser auto reload simply by saving any file. I swear this fairly simple setup saved my 2-3 hours on this project easy.
