Scoped slots in Vue enable child components to pass data back to parent slot content, creating powerful template patterns where child components provide data for parent-defined rendering logic. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented scoped slots in countless Vue components for data tables, lists, and flexible UI patterns where parent components need access to child data. From my expertise, the most effective approach is using slot props to pass data from child to parent with template v-slot directive for clean consumption. This method provides powerful component composition with data flow from child to parent and highly customizable rendering patterns.
