The maintainers of Vue.js have recently published their official style guide.
This site contains a set of guidelines we use to bring our projects to a good end. We decided to document our workflow because consistency is one of the most valuable traits of maintainable software. The contents of this site exist for ourselves—more importantly, our future selves—and for giving future collegues a reference to our way of doing things and their quirks. The guidelines cover workflow, code style, and other little things we consider worth documenting.
