One year ago I wrote my third article in a series where I researched front end tools, and with all that I learned I began to improve our front end stack at Sling. It’s the big Angular app that I wrote about, on which I’ve worked for 2.5 years now. Back then we used Gulp, Bower and Less. No modules, no ES6, barely any unit tests. We still use Angular 1.x, but a lot has changed in the last 12 months!
