The most common way I see on the wild is by separating in categories: - package.json - src |- main.js |- components |- pages \- widgets |- directives |- helpers |- mixins |- router \- store This works for both small projects (but you might not have directives/mixins/router/store) and larger projects (but you might have to add more subfolders inside components/pages because you will start breaking down components).
